Abstract The proliferation of renewable energy resources and the incorporation of various types of energy bring opportunities as well as new challenges to the planning and operations within integrated energy systems (IESs). To better characterize multiple uncertain variables within IES, reducing wind power curtailment and minimizing costs, this paper proposes an IES collaborative planning model with EHs, in which uncertain variables are depicted by Z-numbers. Firstly, Z-number incorporates both fuzzy and probabilistic uncertainties, allowing the representation of uncertain variables with credibility information in constraints. Secondly, simplifying Z-numbers into an engineering-applicable method reduces the complexity of model resolution. Thirdly, to fully leverage the complementary transformation characteristics among different energy sources, the optimization model includes decisions on the capacity of energy conversion and energy storage components within EHs. Moreover, outside the EHs, conventional generator dispatches, and the hardening of electric-gas grid decisions are also included. Finally, the model is verified on an IES that involves the coupling of a six-node power system and a six-node gas system, and numerical results validate that wind power output values represented by Z-numbers have a standard deviation of only 0.33 from actual values. Furthermore, different credibility information in Z-numbers significantly impacts planning outcomes; an increased DR credibility can be conducive to reducing wind curtailment with 45KW and help cost-savings with 4.05%.

Abstract Perovskite solar cells' (PSCs) potential lead leakage seriously threatens ecosystems and human health, significantly hindering their commercialization. In this paper, we develope a cost‐effective (less than 2$/m2) and long‐term stable SSP film by mixing sulfonated SiO2 with polyvinyl alcohol (PVA). Combined with polydimethylsiloxane (PDMS) forming the encapsulation layer, it can effectively prevent over 99% of lead leakage under simulated adverse weather conditions with different structures of devices (p‐i‐n and n‐i‐p) and modules. Even after 160 days of air storage, the film maintains excellent lead sequestration efficiency. Additionally, it has no negative impact on the performance and stability. This work offers a practical and economical strategy to mitigate the toxicity of perovskite photovoltaic devices, thereby promoting their commercialization.

Abstract With triboelectric nanogenerators (TENGs) introduced in 2012, they have emerged in the fields of flexible wearable electronics, portable energy, Internet of Things (IoTs), and biomedicine by virtue of their lightweight, high‐energy conversion, low cost, and material selectivity. However, as the application areas of TENGs increase, ambient humidity and human movement generate sweat and moisture that can lead to a decrease in output, so exploring how TENGs operate in high humidity environments is critical to their long‐term development. In this paper, different strategies are introduced to enhance TENGs in high humidity environments, such as encapsulation, construction of hydrophobic/superhydrophobic surfaces, and hydrogen bonding enhancement, and discuss the applications of humidity‐resistant TENGs in fields such as self‐powered sensors, energy harvesters, and motions, and so forth. Finally, we explore the future directions and routes for the development of humidity‐resistant TENGs.

Abstract Lithium‐ion batteries (LIBs) are at the forefront of technological innovation in the current global energy‐transition paradigm, driving surging demand for electric vehicles and renewable energy‐storage solutions. Despite their widespread use and superior energy densities, the environmental footprint and resource scarcity associated with LIBs necessitate sustainable recycling strategies. This comprehensive review critically examines the existing landscape of battery recycling methodologies, including pyrometallurgical, hydrometallurgical, and direct recycling techniques, along with emerging approaches such as bioleaching and electrochemical separation. Our analysis not only underscores the environmental and efficiency challenges posed by conventional recycling methods but also highlights the promising potential of electrochemical techniques for enhancing selectivity, reducing energy consumption, and mitigating secondary waste production. By delving into recent advancements and juxtaposing various recycling methodologies, we pinpoint electrochemical recycling as a pivotal technology for efficiently recovering valuable metals, such as Li, Ni, Co, and Mn, from spent LIBs in an environmentally benign manner. Our discussion extends to the scalability, economic viability, and future directions of electrochemical recycling, and advocates for their integration into global battery‐recycling infrastructure to address the dual challenges of resource depletion and environmental sustainability.

Abstract Lead halide perovskites (LHPs), have attracted considerable attention across various applications owing to their exceptional optoelectronic properties. However, the main challenge hindering the broad adoption of lead halide perovskites lies in their stability and toxicity. In this review, we summarize the outstanding properties of platinum (Pt) halide perovskites, with a particular focus on the stability and applications of Cs2PtI6 and its derivatives. Cs2PtI6 has shown promising efficiency for photovoltaic devices, as well as photoelectrochemical water splitting with stable behavior in acid or basic conditions. Cs2PtI6 also shows promise in gas sensing and thermoelectric devices. The emergence of 2D Pt (II) halide perovskites opens up new avenues for environmentally friendly materials for photonic and optoelectronic devices like room temperature phosphoresce and triplet‐triplet annihilation (TTA) based up‐conversion.

Abstract Goals of high efficiency, morphological analysis, and the ability to produce organic solar cell (OSC) sub‐modules using halogen‐free solvents are demanding. In this study, a robust conjugated polymer with thienothiophene π‐spacer with pendant alkyl side chain (NapBDT‐C12) was synthesized and used to fabricate sub‐modules. Excellent efficiencies were demonstrated by a NapBDT‐C12 integrated ternary blend, which was used to produce stable small‐area‐to‐sub‐module devices using O‐xylene. The efficiency of the NapBDT‐C12 added small‐area ternary devices (PM6:NapBDT‐C12:L8‐BO) was 18.71%. Owing to the controlled homogeneity of the blend with favorable nanoscale film morphology, enhanced carrier mobilities, and exciton dissociation/splitting properties, contributed to the efficiencies of small‐area‐to‐sub‐module OSCs. Moreover, a 55 cm2 sub‐module with an efficiency of 14.69% was accomplished by bar coating using O‐xylene under ambient conditions. This study displays the potential of a ternary blend based OSC device to produce high efficiency scalable sub‐modules at ambient conditions.

Abstract In perovskite solar cells (PSCs), expensive gold or silver metal has traditionally been utilized as the rear electrode for highly efficient performance. In this context, carbon nanotube (CNT) electrodes have been considered promising rear electrodes because of their excellent electrical conductivity, mechanical strength, and chemical stability in PSCs. Despite these favorable characteristics, concerns have been raised about the power conversion efficiency (PCE) and stability of PSCs based on CNTs due to the porosity of CNT electrodes. In this study, we employed both poly(triarylamine) (PTAA) infiltration and rear electrode hidden encapsulation approaches to address issues related to the porosity of thin‐walled carbon nanotube (TWCNT) electrodes to achieve high efficiency and stability. The infiltration of low‐molecular‐weight PTAA into the TWCNT electrode reduced electrode porosity while simultaneously improving the interfacial contact of the TWCNT layer with the perovskite layer. Furthermore, a novel encapsulation design was employed to prevent air and water exposure of the TWCNT electrode, which significantly enhanced device stability. PSCs with TWCNT rear electrodes developed on the basis of these strategies have the best PCE of 19.5% and show long‐term stability, retaining 96% and 74% of the initial PCE after 225 h at maximum power point tracking under AM 1.5G illumination and 916 h at 85°C/85% relative humidity, respectively.

Abstract Stability and oxidation are major bottlenecks in improving the performance of Sn‐based perovskite solar cells. In this study, we present the formation of an n‐type Cs2SnI6 double‐perovskite (Sn‐DP) layer on a (PEAI)0.15(FAI)0.85SnI2 perovskite (Sn‐P) layer using an orthogonal solution‐processable spray‐coating method. This novel approach achieves a minimized Voc loss of 0.38 V and a PCE of 12.9% under 1 sun conditions. The n‐type DP layer effectively passivates tin vacancies, suppresses Sn2+ oxidation, reduces defects, and enhances electron extraction. Furthermore, the Sn‐DP/Sn‐P‐based solar cells exhibit excellent light‐soaking stability for 1000 h in the air under continuous one sun illumination, which is attributed to the stable Sn4+ state of the DP layer. Our experimental and theoretical investigations reveal that the type‐II band alignment between Sn‐DP and Sn‐P enhances the stability of the solar cells. The proposed Sn‐DP/Sn‐P architecture offers a promising pathway for developing Sn‐based solar cells.

Abstract Atomically dispersed metal and nitrogen co‐doped carbon (MNC) is a promising oxygen reduction reaction (ORR) catalyst for electrochemical energy storage and conversion applications but typically suffers from low durability and activity under the acidic conditions of practical polymer electrolyte exchange membrane fuel cells (PEMFCs). Recently, the performance of MNC nanocomposites under acidic ORR conditions has been enhanced by exploiting the synergistic coupling effects of their constituents (single‐atom sites, nanoclusters, and nanoparticles). The unique geometric structures formed by the coupling of diverse sites in these nanocomposites provide optimal electronic structures and efficient reaction pathways, thus resulting in high activity and long‐term durability. This work provides an overview of MNC nanocomposites as ORR electrocatalysts under practical PEMFC conditions, focusing on activity and durability enhancement methods and highlighting the strategies used to prepare electrocatalytically efficient MNC nanocomposites containing no or low amounts of platinum group metals. Progress in the development of advanced MNC nanocomposites as acidic ORR catalysts is discussed, and the pivotal role of synergistic effects resulting from the coupling sites within the nanocomposites is explored together with the characterization methods used to elucidate these effects. Finally, the challenges and prospects of developing MNC nanocomposites as next‐generation electrocatalysts are presented.

Abstract MAPbI3 is the most attractive perovskite, but toxicity and instability issues hinder its commercial applications. Stability can be improved by halide mixing; however, Pb‐free perovskites are designed to alleviate the toxicity and to enable green photovoltaics (PVs). To this end, MAPbI3‐xClx, FASnI3‐xClx and CsSbCl4 films are deposited by spay pyrolysis technique in atmospheric conditions. SEM images demonstrated that through this process, high quality film fabrication is possible. Color of the precursor solutions changes with stirring time. High crystallinity and existence of mixed‐phases are confirmed by XRD analysis. Compositions greatly impact the morphology and optical properties. Value of α is larger than 105 cm−1 for all films. Band gaps of FASnI3‐xClx and CsSbCl4 are 1.46 eV and 1.52 eV, which are more suitable for PVs, optoelectronic applications than MAPbI3‐xClx (Eg = 1.59 eV). The efficiency was obtained as 16.34%, 9.90%, and 13.08% for deposited MAPbI3‐xClx, FASnI3‐xClx, and CsSbCl4 films. The lower efficiency can further be enhanced by optimizing parameters, and in this study it was found as 20.78%, 11.93%, and 18.02%. Theoretical calculations show the films can easily produce O2 by a strong oxidation process. Thus, the favorable characteristics of FASnI3‐xClx and CsSbCl4 make alternative Pb‐free perovskites for PV, electronic, and optoelectronic applications.

Abstract Lead halide perovskites exhibit a very wide color gamut due to their extremely narrow emission spectra, typically characterized by a full‐width at half‐maximum (FWHM) of less than 20 nm. Significant advancements have been made in developing highly efficient and stable green, red, and near‐infrared perovskite light‐emitting diodes (PeLEDs). However, achieving efficient and stable pure blue‐emitting PeLEDs remains a significant challenge. In this work, we successfully synthesized monoanionic octyl‐phosphonate capped CsPbBr3 nanoplatelets (OPA‐NPLs) using a combination of octyl‐phosphonic acid and oleylamine at room temperature, diverging from common approaches that necessitate complex high‐temperature methods, such as hot injection, to accommodate short‐chain ligands. The OPA‐NPLs exhibit pure blue photoluminescence at 462 nm with a FWHM of 14 nm. Compared with CsPbBr3 nanoplatelets synthesized using oleic acid, OPA‐NPLs demonstrate significantly improved thermal stability and higher photoluminescence quantum yield (PLQY) of 90%. Additionally, we introduced Poly[(9,9‐bis(3′‐((N,N‐dimethyl)‐N‐ethylammonium)‐propyl)‐2,7‐fluorene)‐alt‐2,7‐(9,9‐dioctylfluorene)]dibromide (PFN‐Br), a conjugated polyelectrolyte material, as a hole transport layer. This facilitated energy transfer between PFN‐Br and the CsPbBr3 nanoplatelets. The resulting device demonstrated an electroluminescence peak at 462 nm, an extremely narrow FWHM of 14 nm, and a maximum external quantum efficiency (EQE) of 4%. Notably, the device maintained pure blue emission without spectral peak shift even during degradation caused by excess joule heating.

Abstract The sulfur utilization efficiency of lithium–sulfur batteries is often limited by the uncontrolled electrodeposition of the insulating Li2S and the resulting electrode passivation. Herein, purposeful electrode and electrolyte design is used to realize site‐selective three‐dimensional (3D) Li2S electrodeposition and thus mitigate the above problem. Site‐selective Li2S nucleation is induced at the tips of CoP nanoneedles grown on a carbon cloth electrode, and the 3D growth of Li2S at these tips without the passivation of the inner part is achieved using a LiBr‐containing high‐donor‐number electrolyte. The controlled Li2S morphology is rationalized by considering the tip effect, the energy of Li2S binding on the electrode surface, and the solubility of Li2S in the electrolyte. Owing to the suppressed electrode passivation, CoP nanoneedle–decorated carbon cloth electrode and LiBr‐containing electrolyte deliver a capacity of >1400 mAh gs−1 at a current density of 0.33 A gs−1. Thus, this work paves the way for the active control of Li2S morphology for high‐performance lithium–sulfur batteries.

Abstract Double transition metal (DTM) MXenes are a recently discovered class of two‐dimensional composite nanomaterials with excellent potential in energy storage applications. Since their emergence in 2015, DTM MXenes have expanded their composition boundary beyond traditional single‐metal carbide and nitride MXenes. DTM MXenes offer tunable structures and properties through variations in the constituent transition metals and positioning within the layered lattice. These MXenes can exist in two primary forms: ordered DTMs and solid solutions. The compositional versatility of DTM MXenes offers opportunities to enhance their performance in electrochemical energy storage applications. However, the quality, stability, and surface chemistry of DTM MXenes are influenced by several factors, including the etching process, etchant type, and synthesis route. Currently, limited literature is available on experimentally synthesized DTM MXenes, with most studies focusing on carbide‐based MXenes. Most of the articles have dedicated their efforts only to generalized synthesis strategies. Although extensive theoretical studies have explored the suitability of etchants, synthesis parameters, and methods for producing high‐quality MXene with selective terminal functional groups, their stability issues have not been thoroughly examined. This review addresses various types of DTM MXenes, their synthesis techniques, and the impact of these methods on their physicochemical properties and electrochemical performance. Additionally, it provides a critical analysis of the causes of instability in MXenes, particularly DTMs, from synthesis to application. The challenges associated with these materials are discussed, along with opportunities and prospects for enhancing synthesis, structural tuning, surface modification, and applications in electrochemical energy storage.

One such technique involves introducing rare earth metals or creating heterostructures with compounds based on rare earth metals. The incorporation of rare earth metals significantly enhances the activity by many folds, while their compounds offer structural stability and the ability to manipulate the electronic properties of the original system. These factors have led to a recent boom in investigations on rare earth metal‐based electrocatalysts.

It is expected that this particular effort will benefit a broad audience and stimulate more research in this area of interest.

Abstract Rechargeable aqueous zinc (Zn) ion batteries (AZIBs) are gaining popularity in large‐scale energy storage due to their low cost, high safety, and environmental friendliness; however, dendrite growth and side reactions in Zn metal anodes limit their practical applications. Additionally, the difficulty of developing successful passivation of Zn anodes, combined with large‐area coating of protective layers, remains a major limitation to the commercialization of AZIBs. Here, we introduce two‐dimensional (2D) nanomaterials including MoS2, h‐BN, and Ti3C2Tx MXene as protective layers for Zn anodes, created on a Zn surface using a scalable, large‐area spray‐coating process. Examinations of electrochemical performance‐related material characterizations revealed that a specific type of 2D material with an optimal thickness prevents vertical growth of Zn dendrites, as well as side reactions including hydrogen evolution and corrosion, resulting in stable device operation with minimal overpotential and extended life, even under harsh measurement conditions. The highly stable MoS2@Zn anode allowed the MoS2@Zn//MnO2 full cell to achieve significantly more stable capacity retention, compared with the bare Zn//MnO2 cell. Our versatile and scalable solution‐based coating technique for easily forming large‐area 2D protective layers on Zn anodes offers new insights concerning improvements to AZIB reliability and performance.

Abstract Developing efficient electrocatalysts with low‐cost for the urea oxidation reaction (UOR) is a significant challenge in energy‐saving H2 production owing to its lower thermodynamic potential. Heteroatom incorporation strategy has been proven to boost electrocatalytic activity by altering electronic structures and revealing more active sites on catalysts. Herein, nickel hydroxide nanosheets with various vanadium incorporation (Vx‐Ni(OH)2) were developed through a facile hydrothermal approach. By optimizing the incorporated vanadium contents, V6‐Ni(OH)2 catalyst exhibited easily accessible active sites and enhanced charge transfer with structural advantages, then assembled as the working electrode for urea‐assisted H2 production. Consequently, V6‐Ni(OH)2 catalyst demonstrated superior UOR activity compared with other incorporated samples with an overpotential of 1.33 V and a Tafel slope of 28.3 mV dec−1. Theoretical calculations revealed that the improved UOR activity was attributed to the potential determining step of V‐Ni(OH)2, which exhibited lower energy in comparison with the pristine Ni(OH)2 and increased electronic states density near the Fermi level. Both experimental and theoretical calculations confirmed vanadium incorporation on Ni(OH)2 could modify the electronic structure of Ni(III) species, improving electrical conductivity, and optimizing the adsorption energy for key reaction intermediates. Furthermore, the crucial contribution of vanadium incorporation with optimized electronic structures to the high UOR activity of Ni(OH)2 is demonstrated.

Abstract In order to cope with the increasingly serious problem of energy shortage, supercapacitors have been developed as a clean and renewable energy source, and the supercapacitors with excellent energy density and long cycle life are imperative. Here, by employing a facile liquid–liquid (L‐L) interfacial method at room temperature (RT), a set of two‐dimensional (2D) metal complex nanosheets N1‐N3 have been synthesized by the facile coordination between Co2+ ion and 2,3,6,7,10,11‐hexaiminotriphenylene (HITP). Given the layered superstructure with well‐ordered nanopores, the N1‐N3 electrodes displayed excellent capacities of 4751.9, 5770.9 and 6075.2 F g−1 at 1 A g−1, and a good cyclic stability with 92.1% capacity retention after 1000 cycles for the N3 electrode. The asymmetric supercapacitor device with N3 as the positive electrode delivers a maximum energy density of 238.2 Wh kg−1 at a power density of 1610.1 W kg−1 and an excellent cycling stability with a capacitance retention of 109.1% after 5000 cycles. This is the best electroactive bottom‐up metal complex nanosheet reported so far for use in supercapacitor, which greatly expands the applicability of this 2D nanomaterial in energy device applications.

Abstract Three‐dimensional (3D) current collectors (CCs) have emerged as an effective strategy to inhibit dendrites and ensure the safety of lithium (Li) metal anodes. However, existing 3D CCs are generally too heavy (typically tens of mg cm−2) or too thick (tens to hundreds of micrometers), making large‐scale production and further application challenging. Additionally, the use of single‐component 3D CCs, whether electrically active or inert, only exhibits limited effects on stabilizing Li anodes. Here, we present a scalable screen‐printing technique for the synthesis of ultralight (~0.4 mg cm−2) and ultrathin (~0.54 μm) SiO2 grids on Cu foil to regulate both the vertical electric field and Li‐ion concentration by forming an electrically active/inert dual‐function architecture. This technology breaks the limitations of traditional 3D CCs in material/fabrication costs, weight, thickness and especially, scalability for large‐scale fabrication. By using this dual‐function architecture, our Cu@SiO2‐grid CCs (~8.31 mg cm−2), which are even lighter than the original Cu‐foil CCs (~8.85 mg cm−2), realize an ultra‐smooth anode surface without Li dendrites, and thus leads to an ultra‐long cyclic life of over 1500 h at 1 mA cm−2. The assembled Li metal batteries demonstrate excellent capacity retention of ~80% over 400 cycles at 1 C and ~ 76% over 250 cycles at 5 C, which highlight the promising 3D CCs for practical applications.

Abstract MoS2 as a typical layered transition metal dichalcogenide (LTMD) has attracted considerable attention to work as sodium host materials for sodium‐ion batteries (SIBs). However, it suffers from low semiconducting behavior and high Na+ diffusion barriers. Herein, intercalation of N‐doped amorphous carbon (NAC) into each interlayer of the tiny MoS2 nanosheets embedded on rGO conductive network is achieved, resulting in formation of rGO@MoS2/NAC hierarchy with interoverlapped MoS2/NAC superlattices for high‐performance SIBs. Attributed to intercalation of NAC, the resulting MoS2/NAC superlattices with wide MoS2 interlayer of 1.02 nm facilitates rapid Na+ insertion/extraction and accelerates reaction kinetics. Theoretical calculations uncover that the MoS2/NAC superlattices are beneficial for enhanced electron transport, decreased Na+ diffusion barrier and improved Na+ adsorption energy. The rGO@MoS2/NAC anode presents significantly improved high‐rate capabilities of 228, 207, and 166 mAh g−1 at 20, 30, and 50 A g−1, respectively, compared with two control samples of pristine MoS2 and MoS2/NAC counterparts. Excellent long‐term cyclability over 10 000 cycles with extremely low capacity decay is demonstrated at high current densities of 20 and 50 A g−1. Sodium‐ion full cells based on the rGO@MoS2/NAC anode are also demonstrated, yielding decent cycling stability of 200 cycles at 5C. Our work provides a novel interlayer strategy to regulate electron/Na+ transport for fast‐charging SIBs.

Abstract Lithium‐ion composite solid electrolyte membranes embedded with Li1.3Al0.3Ti1.7P3O12 and poly(vinylidene fluoride) are prepared using a facile casting method. Furthermore, we added LiI as an active agent for decomposing the anode product. The synergy resulted in a high conductivity of 7.4 mS·cm−1 and lithium‐ion mobility of 0.59 and a reduction of the overpotential to 0.86 V for lithium–oxygen batteries (LOBs). The membrane has enhanced Young's modulus of 6.6 GPa that effectively blocked the lithium dendrite growth during the battery operation and puncturing to the membrane led to a significant LOB cycle life of 542 cycles. Meanwhile, Li|Li symmetrical battery overpotential maintained at 42 mV after 470 h of operation.

Abstract The human body continuously generates ambient mechanical energy through diverse movements, such as walking and cycling, which can be harvested via various renewable energy harvesting mechanisms. Triboelectric Nanogenerator (TENG) stands out as one of the most promising emerging renewable energy harvesting technologies for wearable applications due to its ability to harness various forms of mechanical energies, including vibrations, pressure, and rotations, and convert them into electricity. However, their application is limited due to challenges in achieving performance, flexibility, low power consumption, and durability. Here, we present a robust and high‐performance self‐powered system integrated into cotton fabric by incorporating a textile‐based triboelectric nanogenerator (T‐TENG) based on 2D materials, addressing both energy harvesting and storage. The proposed system extracts significant ambient mechanical energy from human body movements and stores it in a textile supercapacitor (T‐Supercap). The integration of 2D materials (graphene and MoS2) in fabrication enhances the performance of T‐TENG significantly, as demonstrated by a record‐high open‐circuit voltage of 1068 V and a power density of 14.64 W/m2 under a force of 22 N. The developed T‐TENG in this study effectively powers 200+ LEDs and a miniature watch while also charging the T‐Supercap with 4‐5 N force for efficient miniature electronics operation. Integrated as a step counter within a sock, the T‐TENG serves as a self‐powered step counter sensor. This work establishes a promising platform for wearable electronic textiles, contributing significantly to the advancement of sustainable and autonomous self‐powered wearable technologies.

Abstract Global trends toward green energy have empowered the extensive application of high‐performance energy storage systems. With the worldwide spread of electric vehicles (EVs), lithium‐ion batteries (LIBs) capable of fast‐charging have become increasingly important. Nonetheless, state‐of‐the‐art LIBs have failed to satisfy the demands of prospective customers, including rapid charging, extended cycle life, and high energy density. Addressing these challenges through innovations in material science and other advanced battery technologies is essential for meeting the growing demands of prospective customers. Besides the choice of active materials, electrolyte formulation has a significant impact on the fast‐charging performance and cycle life of LIBs over a wide range of temperatures. The liquid electrolyte is typically composed of lithium salts to provide an ion source, solvents to carry Li+ ions, and functional additives to build a stable solid electrolyte interphase (SEI). To enable the fast movement of Li+ ions, the liquid electrolytes should have low viscosity and high ionic conductivity. Meanwhile, SEI layers must be thin, uniform and ionically conductive. Furthermore, the low binding energy of the solvent facilitates desolvation of the solvation sheath, enabling fast Li+ ion transport to the anode during fast charging. This review provides the latest insights into rapid Li+ ion transport during fast charging, focusing on ensuring a deeper understanding of liquid electrolyte chemistry. The involvement of existing electrolyte mechanisms in materials discovery will develop electrolyte engineering techniques to improve the fast‐charging performance of batteries over a wide temperature range and will also facilitate the development of EV‐adoptable advanced electrodes.

Abstract In the rapidly advancing field of information technology, passive sensors with the exemption of external power input can serve as intelligent instruments for end‐node data acquisition. 3D perovskites have been recognized as a superior optoelectronic material but suffering from notorious instability due to their “soft lattice” nature. Replacing by their 2D counterparts in these photo‐sensing applications can boost the reliability level. However, traditional fabrication for 2D perovskite relay on wet chemistry methods, exhibiting complication, and inefficiency in making high‐quality films for device integration. This study unveils a new solid–solid conversion routing toward a direct transformation from 3D orientated films into 2D highly crystalline configuration, based on a spontaneous lattice regulation mechanism through an amine steam treatment. The resultant 2D film exhibits greater orientational micromorphology and a distinct monochromatic narrowband light sensing behavior after integration into a self‐powered photodetector. This method on perovskite conversion bears the promise of advanced future‐manufacturing for high‐performance photonic sensing.

Abstract Defect passivation based on Lewis acid–base chemistry has been regarded as an effective strategy to improve the photovoltaic performance and stability of perovskite solar cells (PSCs). Here, we report on tertiary phosphine oxides (R3PO) as materials for defect passivation, where photovoltaic performance was investigated depending on the substituents R. Electron‐donating ability of the substituents in R3PO was found to play an important role in passivation. Cyclohexyl substituent was better in achieving photovoltaic performance than linear hexyl substituent. The heterocyclic morpholine substituent bearing oxygen and nitrogen in cyclohexyl form further improved photovoltaic performance due to its enhanced electron‐donating ability. Compared with an untreated PSC, the trimorpholinophosphine oxide (TMPPO)‐treated PSC improved the power conversion efficiency from 21.95% to 23.72%. Additionally, the dark‐storage stability test with an unencapsulated device showed that the TMPPO‐treated device maintained 92.7% of its initial PCE after 1250 h, while 86.8% was maintained for the untreated device. Three hundred hour‐light‐soaking of the encapsulated devices revealed that the operational stability of the TMPPO‐treated PSC was superior to the untreated device.

Abstract Metal–organic frameworks (MOFs) are a class of promising nanomaterials for atmospheric water harvesting (AWH), especially in arid remote areas. However, several challenges are still faced for practical applications because of the dissatisfied water adsorption/desorption properties in terms of the capability, kinetics, and stability. Herein, we report the facile synthesis of a nano‐sized octahedral nitrogen‐modified MOF‐801 that exhibits superior solar‐powered AWH performance using a custom‐made device, with a state‐of‐the‐art water harvesting ability up to 4.64LH2OkgMOFs−1 from air upon 12‐h test under a relative humidity (RH) of 30% and simulated sunlight irradiation. The nitrogen‐modified MOF‐801 with rapid sorption–desorption kinetics, uptakes 0.29gH2OgMOFs‐1 of water at 30% RH within 30 min and releases 90% of the captured water within 10 min under 1‐sun illumination. The success relies on N‐doping‐induced mixed‐linkers in the form of 2,3‐diaminobutanedioic acid and fumaric acid in the unique pore structures of the MOFs for rapid and high‐capacity water capture. The N‐doped MOF‐801 with water uptake capacity, fast adsorption kinetics, and cycle stability sheds light on the practical use of MOFs for effective solar‐powered water harvesting from droughty air.

Abstract Indoor photovoltaics are limited by their inherently low‐photogenerated carrier density, leading to heightened carrier recombination and adverse leakage currents compared with conventional solar cells operating under 1 sun condition. To address these problems, this work incorporates a porous insulating interlayer (Al2O3) in perovskite devices, which effectively mitigates recombination and parasitic leakage current. A systematic investigation of the relationship between shunt resistance, photocarrier generation, and recombination at different light intensities demonstrates the effectiveness of the alumina interlayer in perovskite solar cells under low‐light conditions. Moreover, the practicability of the alumina interlayer was demonstrated through its successful implementation in a large‐area perovskite solar module (PSM). With bandgap engineering, the optimized PSM achieves a remarkable power conversion efficiency of 33.5% and a record‐breaking power density of 107.3 μW cm−2 under 1000 lux illumination. These results underscore the potential of alumina interlayers in improving energy harvesting performance, particularly in low‐light indoor environments.

Abstract As global urbanization intensifies, there is an increasing need for highly sensitive and accurate environmental monitoring devices that can meet the demands of specific gas sensing applications with low power consumption. This study focuses on enhancing the sensitivity of MXene‐based chemiresistive sensors for detecting CO2(g) and NO2(g) under zero‐bias operation. This study shows that lignin hybridization effectively improves the sensitivity of a Ti3C2Tx MXene‐based chemiresistive sensor; under zero‐bias operation, lignin hybridization increases the sensitivity to 15 ppm NO2(g) and CO2(g) by 157.38% and 297.95%, respectively. When deposited on a flexible substrate, the MXene/lignin flexible sensor shows a similar response and sensitivity to 15 ppm NO2(g) and CO2(g) under 38° curvature compared to the planar sensor. Consequently, the MXene/lignin hybrid sensor is attractive for room temperature and zero‐bias NO2(g) and CO2(g) detection. The MXene/lignin flexible sensor serves as a model system for advanced solid‐state sensory platforms suitable for curved structures.

Abstract The development of advanced anode materials for lithium‐ion batteries that can provide high specific capacity and stable cycle performance is of paramount importance. This study presents a novel approach for synthesizing molecular‐level homogeneous carbon integration to porous SiO2 nanoparticles (SiO2@C NPs) tailored to enhance their electrochemical activities for lithium‐ion battery anode. By varying the ratio of the precursors for sol–gel reaction of (phenyltrimethoxysilane (PTMS) and tetraethoxysilane (TEOS)), the carbon content and porosity within SiO2@C NPs is precisely controlled. With a 4:6 PTMS and TEOS ratio, the SiO2@C NPs exhibit a highly mesoporous structure with thin carbon and the partially reduced SiOx phases, which balances ion and charge transfer for electrochemical activation of SiO2@C NPs resulting remarkable capacity and cycle performance. This study offers a novel strategy for preparing affordable high capacity SiO2‐based advanced anode materials with enhanced electrochemical performances.

Abstract Formamidinium lead iodide (FAPbI3) and SnO2 are a promising pair of halide perovskite and electron transport layer (ETL). However, FAPbI3 and SnO2 have inherent problems such as high crystallization temperature of FAPbI3 and surface defects of SnO2 like oxygen vacancies. They cause low crystallinity, non‐uniform grain growth, and more interface defects, leading to carrier recombination and leakage current. The passivation of the interface between FAPbI3 and SnO2 is an effective process to address these materials issues. Herein, a dual role of lead sulfide (PbS) quantum dots (QDs) in the interface passivation is explored. PbS QDs which are introduced to the interface between FAPbI3 and ETL, link to Sn‐dangling bonds of SnO2 ETLs and anchor the iodine atoms of FAPbI3. This changes considerably lower nonradiative recombination, achieve a better energetic alignment between ETL and PbI3, and facilitate electron extraction, leading to a power conversion efficiency of 21.66%.

Abstract Wearable photothermal materials can capture light energy in nature and convert it into heat energy, which is critical for flexible outdoor sports. However, the conventional flexible photothermal membranes with low specific surface area restrict the maximum photothermal capability, and loose structure of electrospun membrane limits durability of wearable materials. Here, an ultrathin nanostructure candle soot/multi‐walled carbon nanotubes/poly (L‐lactic acid) (CS/MWCNTs/PLLA) photothermal membrane is first prepared via solvent‐induced recrystallization. The white blood cell membrane‐like nanowrinkles with high specific surface area are achieved for the first time and exhibit optimal light absorption. The solvent‐induced recrystallization also enables the membrane to realize large strength and durability. Meanwhile, the membranes also show two‐sided heterochromatic features and transparency in thick and thin situations, respectively, suggesting outstanding fashionability. The nano‐wrinkled photothermal membranes by novel solvent‐induced recrystallization show high flexibility, fashionability, strength, and photothermal characteristics, which have huge potential for outdoor warmth and winter sportswear.

Based on the characteristics of the current state of the use of renewable energy sources (RES) in the world and in Russia, the role of solar energy in solving one of the urgent problems of the development of modern society - energy transition to the use of low-carbon energy sources is considered. The volumes of electricity produced and the reduction of CO2 emissions at photovoltaic stations operating in the regions of Russia at the beginning of 2022 were evaluated and analyzed. The Republic of Kalmykia and Altai were singled out, which have the largest shares of solar electricity in the energy balances, 35.7 and 23.2%, respectively. The problems of assessing the natural resource risks of using solar resources in the Russian Federation in connection with the climatic zoning of the territory are considered. The authors propose a method for assessing the degree of risk of using solar resources based on calculating the characteristics of the variability of solar radiation on the earth’s surface, assessing and mapping the level of natural resource risks. The levels of resource risks in the development of solar energy for the Orenburg and Astrakhan regions, leaders in the development of solar energy in Russia, were assessed.

Abstract Over the years, lead‐based piezoelectric ceramics found extensive use in vital fields such as sensors and actuators. Despite their exceptional electromechanical properties, lead‐containing materials pose severe environmental risks and foster a new era of lead‐free piezoelectric materials after decades of research. However, recent comparative assessments of potassium sodium niobate (KNN) versus lead zirconate titanate (PZT) piezoelectric materials proposed that the environmental damage already presented before use due to raw material extraction and processing, invoking concerns on the true greenness of the lead‐free alternatives. Nevertheless, many other factors deserve further consideration, for example, reference geometry and life cycle stage. Herein, the comprehensive life cycle assessment is undertaken on PZT and KNN‐based ceramics with a unit volume of 0.001 m3 from cradle to gate. Results show that PZT exhibits higher negative impacts than KNN‐based counterparts, attributed to lead extraction, processing, and associated environmental emissions. Across primary quantitative impact indicators from toxicity, environmental, and resource aspects, KNN‐based ceramics impose fewer risks on the environment and human health, with the overall impact being only 28% of PZT ceramics. Still, more efficient methods are required for KNN‐based ceramics to reduce the high energy consumption and emission during extraction and purification of raw material Nb2O5. This work not only offers critical insights for material development but also serves as a multifaceted reference for advanced fabrication technologies.

Abstract Sedentary, inadequate sleep and exercise can affect human health. Artificial intelligence (AI) and Internet of Things (IoT) create the Artificial Intelligence of Things (AIoT), providing the possibility to solve these problems.

Similarly, a smart pillow, equipped with 15 sensory channels, detects head movements during sleep, identifying 8 sleep patterns with 96.25% accuracy. Ultimately, constructing an AIoT‐based health management system to analyze these data, displaying health status through human‐machine interfaces, offers the potential to help individuals maintain good health.

Abstract The sluggish reaction kinetics has greatly hampered the development of reversible Li‐CO2 batteries. Especially during charge, high charge voltage and possible side reactions during Li2CO3 decomposition require both high activity and strong durability of catalysts. Herein, a strategy of introducing rich sulfur vacancies is proposed, which tailors the configuration of Li2CO3 and the orbital structure of CoS to realize the dual enhancement. The calculation results show that charge redistribution by sulfur vacancies on the catalyst stretches the adsorbed Li2CO3 and consequently facilitates its decomposition. Moreover, the induced vacancies lower the S 2p band center, promoting the electrochemical stability of sulfides. Therefore, Li‐CO2 batteries with sulfur vacancy‐rich CoS exhibit a low overpotential of 1.07 V after 400 h cycling, while batteries with pristine CoS have a short lifespan that the overpotential exceeds 1.75 V after cycling for 200 h. This study not only proposes a strategy to improve both catalytic activity and stability but also paves new avenues for designing advanced catalysts for Li‐CO2 batteries and beyond.

Abstract The productivity of global crop production is under threat caused by various biotic and abiotic adverse conditions, such as plant diseases and pests, which are responsible for 20%–40% of global crop losses estimated at a value of USD 220 billion, and can be further exacerbated by climate change. Agricultural industries are calling for game‐changer technologies to enable productive and sustainable farming. Carbon dots (C‐dots) are carbon‐based nanoparticles, smaller than 50 nm, exhibiting unique opto‐electro‐properties. They have been shown to have positive impact on managing diverse biotic and abiotic stresses faced by the crops. Owing to their versatile carbon chemistry, the surface functionalities of C‐dots can be readily tuned to regulate plant physiological processes. This review is focussed on establishing the correlations between the physiochemical properties of C‐dots and their impacts on plants growth and health. The summary of the literature demonstrates that C‐dots hold great promise in improving plant tolerance to heat, drought, toxic chemicals, and invading pathogens.

Abstract Advancing fast‐charging technology is an important strategy for the development of alkali metal ion batteries (AMIBs). The exploitation of a new generation of anode material system with high‐rate performance, high capacity, and low risk of lithium/sodium/potassium plating is critical to realize fast‐charging capability of AMIBs while maintaining high energy density and safety. Among them, phosphorus‐based anodes including phosphorus anodes and metal phosphide anodes have attracted wide attention, due to their high theoretical capacities, safe reaction voltages, and natural abundance. In this review, we summarize the research progress of different phosphorus‐based anodes for fast‐charging AMIBs, including material properties, mechanisms for storing alkali metal ions, key challenges and solution strategies for achieving fast‐charging capability. Moreover, the future development directions of phosphorus‐based anodes in fast‐charging AMIBs are highlighted.

Abstract Deformable lithium‐ion batteries (LIBs) can serve as the main power sources for flexible and wearable electronics owing to their high energy capacity, reliability, and durability. The pivotal role of cathodes in LIB performance necessitates the development of mechanically free‐standing and stretchable cathodes. This study demonstrates a promising strategy to generate deformable cathodes with electrical conductivity by forming 3D interconnected elastomeric networks. Beginning with a physically crosslinked polymer network using poly(vinylidene fluoride‐co‐hexafluoropropylene) and 1‐ethyl‐3‐methylimidazolium bis(trifluoromethylsulfonyl)imide ([EMI][TFSI]), subsequent exchange with a 1 M LiPF6 electrolyte imparts elastic characteristics to the cathodes. The resulting LiFePO4 composite electrodes maintained their resistance under 500 consecutive bending cycles at an extremely small bending radius of 1.8 mm and showed high discharge capacity of 158 mAh g−1 with stable potential plateaus in charging and discharging curves. Moreover, flexible cells utilizing the composite electrodes exhibited superior operational stability under rolling, bending, and folding deformations.

Abstract We incorporated triphenylsulfonium triflate (TPST), a sulfonium‐based additive consisting of polar triflate and bulky hydrophobic phenyl rings, to the PbI2 precursor solution for preparation of less‐defect perovskite film via two‐step fabrication. TPST induced localized alterations in the array of the PbI2 structure due to its large size, thereby forming a more discontinuous and coarser surface with a greater number of pinholes and subsequently facilitating more efficient organic–inorganic reactions. As a result, we achieved the production of thick perovskite films with enlarged granules and decreased PbI2 residuals in the two‐step fabrication process. Furthermore, TPST facilitated the passivation of bulk film defects by increasing the binding energy with the defects. Consequently, the ITO/SnO2 np‐based device and the FTO/CBD SnO2‐based device obtained the best PCEs of 23.88% and 24.30%, respectively. Furthermore, the moisture stability of the perovskite was improved by the hydrophobic character of the TPST additive.

Abstract Value‐added conversion of lignocellulose is a sustainable approach. Photo‐refining biomass is in line with current environmental protection strategies. However, photo‐reforming biomass suffers from poor catalyst stability and low conversion efficiency. Here, we designed fructose as a lignocellulosic model. The heterogeneous structure of Prussian blue coating was constructed with a special covalent bond structure of CoCNZn. This structure has a catalytic conversion mechanism that can accelerate electron transfer. Fructose was simultaneously converted to value‐added platform compounds (5‐HMF and formic acid) and gaseous fuels (CO, CH4) with a conversion rate of up to 92.5%, which is more than 1.7 times than that of catalysts without adding Prussian blue. Hydrogen transfer and carbon transfer on the carbon atoms of fructose facilitates the production and accelerates the spillover of CO from formic acid. This work provides new ideas for the development of Prussian blue catalysts and the conversion of pentose.

Abstract The introduction of alkoxy side chains into the backbone of conjugated polymers is an effective way to change their properties. While the impact on the structure and optoelectronic properties of polymer thin films was well‐studied in organic solar cells and transistors, limited research has been conducted on their effects on doping and thermoelectric properties. In this study, the effects of methoxy functionalization of conjugated backbones on the doping and thermoelectric properties are investigated through a comparative study of diketopyrrolopyrrole‐based conjugated polymers with and without methoxy groups (P29DPP‐BTOM and P29DPP‐BT, respectively). Methoxy‐functionalization significantly enhances doping efficiency, converting undopable pairs to dopable ones. This dramatic change is attributed to the structural changes in the polymer film caused by the methoxy groups, which increases the lamellar spacing and facilitates the incorporation of dopants within the polymer crystals. Moreover, methoxy‐functionalization is advantageous in improving the Seebeck coefficient and power factor of the doped polymers, because it induces a bimodal orientational distribution in the polymer, which contributes to the increased splitting of Fermi and charge transport levels. This study demonstrates the impact of methoxy‐functionalization of a conjugated polymer on doping behavior and thermoelectric properties, providing a guideline for designing high‐performance conjugated polymers for thermoelectric applications.

Abstract In the pursuit of carbon neutrality policies, the development of eco‐friendly and intelligent furniture commands a significant role. However, the integration of non‐biodegradable electronic components in smart furniture fabrication has led to substantial electronic waste. Here, we report a straightforward approach, the rapid production of Laser‐Induced Graphene (LIG) on medium‐density fiberboard (MDF), a prevalent recycled wood in furniture production. This LIG electrode is crafted with negligible material ablation in ambient air with the aid of femtosecond laser pulses, without requiring any additional materials, showcasing the highest electrical conductivity (2.781 Ω sq−1) among previously reported lignocellulosic materials‐based LIG. The application of this LIG electrode for lighting, heating, and touch sensors displays sufficient performance for smart furniture implementation. For eco‐conscious furniture, LIG‐based human‐machine interfaces are demonstrated on recycled woods for the facile control of smart devices, which will readily enable IoT‐oriented smart sustainable furniture.

Abstract The practical implementation of aqueous Zn‐ion batteries (ZIBs) for large‐scale energy storage is impeded by the challenges of water‐induced parasitic reactions and uncontrolled dendrite growth. Herein, we propose a strategy to regulate both anions and cations of electrolyte solvation structures to address above challenges, by introducing an electrolyte additive of 3‐hydroxy‐4‐(trimethylammonio)butyrate (HTMAB) into ZnSO4 electrolyte. Consequently, the deposition of Zn is significantly improved leading to a highly reversible Zn anode with paralleled texture. The Zn/Zn cells with ZnSO4/HTMAB exhibit outstanding cycling performance, showcasing a lifespan exceeding 7500 h and an exceptionally high accumulative capacity of 16.47 Ah cm−2. Zn/NaV3O8·1.5H2O full cell displays a specific capacity of ~130 mAh g−1 at 5 A g−1 maintaining a capacity retention of 93% after 2000 cycles. This work highlights the regulation on both cations and anions of electrolyte solvation structures in optimizing interfacial stability during Zn plating/stripping for high performance ZIBs.

Abstract Herein, we synthesized Cr3+/Ln3+ (Er3+, Tm3+)‐codoped rare earth‐based Cs2NaScCl6 double perovskite, and the near‐infrared emission of Ln3+ can be excited by visible light through the energy transfer (ET) from Cr3+ to Ln3+. Moreover, there are two independent emission bands, which stems from 4T2 → 4A2 transition of Cr3+ (970 nm) and f‐f transition of Ln3+ (1542 nm for Er3+ and 1220 nm for Tm3+), respectively. Particularly, both compounds have ultra‐high photoluminescence quantum yield (PLQY) of 60% for 10%Cr3+/6%Er3+‐codoped Cs2NaScCl6 (Er3+ emission: ∼26%) and 68% for 10%Cr3+/4.5%Tm3+‐codoped Cs2NaScCl6 (Tm3+ emission: ∼56%), which can be attributed to the ultra‐high ET efficiency from Cr3+ to Ln3+ and the similar ionic activity of Sc3+ and Ln3+ allowing more dopants enter the host lattice. Considering the excellent stability of the samples, we demonstrated Cr3+/Tm3+‐codoped Cs2NaScCl6 in the applications of near‐infrared imaging and night vision. Finally, we reported 10%Cr3+/4.5%Tm3+/9%Er3+‐tridoped Cs2NaScCl6 and further applied it for optical thermometry.

Abstract Anion exchange is an effective strategy to regulate the composition and optoelectronic properties of perovskite quantum dots (PQDs). Though promising, it is more desirable to synthesize PQDs to avoid the decrease of photoluminescence quantum yield (PLQY). Herein, we developed a ligand mediated anion exchange approach, in which the phase transition from CsPbBr3 QDs to CsPbI3 QDs was observed with the introduction of N‐Acetyl‐l‐cysteine (NAC) and 1,3‐dimethylimidazolium iodide (DMII) aqueous solution in CsPbBr3 QDs solution. NAC is expected to create more halogen vacancies in CsPbBr3 QDs, which provides sufficient adsorption sites for I− ions, resulting in accelerating the anion exchange rate in the process of DMII incorporation. Benefiting from the synergistic ligand mediated anion exchange, high PLQY of 97% and remarkable stability of CsPbI3 QDs are obtained. Furthermore, a white light‐emitting diode (WLED) with a lumen efficiency (LE) of 116.82 lm/W is constructed, showing remarkable stability under continuous operation.

Abstract Perovskite solar cells offer a promising future for next‐generation photovoltaics owing to numerous advantages such as high efficiency and ease of processing. However, two significant challenges, air stability, and manufacturing costs, hamper their commercialization. This study proposes a solution to these issues by introducing a floating catalyst‐based carbon nanotube (CNT) electrode into all‐inorganic perovskite solar cells for the first time. The use of CNT eliminates the need for metal electrodes, which are primarily responsible for high fabrication costs and device instability. The nanohybrid film formed by combining hydrophobic CNT with polymeric hole‐transporting materials acted as an efficient charge collector and provided moisture protection. Remarkably, the metal‐electrode‐free CNT‐based all‐inorganic perovskite solar cells demonstrated outstanding stability, maintaining their efficiency for over 4000 h without encapsulation in air. These cells achieved a retention efficiency of 13.8%, which is notable for all‐inorganic perovskites, and they also exhibit high transparency in both the visible and infrared regions. The obtained efficiency was the highest for semi‐transparent all‐inorganic perovskite solar cells. Building on this, a four‐terminal tandem device using a low‐band perovskite solar cell achieved a power conversion efficiency of 21.1%. These CNT electrodes set new benchmarks for the potential of perovskite solar cells with groundbreaking device stability and tandem applicability, demonstrating a step toward industrial applications.

Abstract The simple‐structural and volatile solid additive 1,4‐dibromobenzene (DBrB) can outperform organic solar cells (OSCs) fabricated with 1,4‐diiodobenzene and 1,4‐dichlorobenzene in terms of power conversion efficiency (PCE). A remarkable PCE of 17.0% has been achieved in a binary OSC based on DBrB‐optimized photoactive materials processed from non‐halogenated solvents, which is mainly attributed to the formation of a three‐dimensional interpenetrating network and the orderly arrangement of the photoactive materials by improving the intermolecular interaction. This optimized morphology enables efficient charge transfer/transport as well as suppressed charge recombination, resulting in the simultaneous increase in all photovoltaic parameters. More importantly, we demonstrate that non‐halogenated solvent‐processed DBrB enabled PM6:Y6‐HU OSCs with an impressive PCE of 18.6%, which is the highest efficiency yet reported for binary OSCs. This study suggests that the novel DBrB volatile solid additive is an effective approach to optimizing the morphology and thereby improves the photovoltaic performance of OSCs.

Abstract Photothermal devices and thermoelectric cells hold great promise for energy generation but integration of the two remains a considerable challenge in real‐life power supply for sensors. Here, a novel photo‐thermo‐electric hydrogel (PTEH‐Interlocking) was constructed by the synthesis of a photothermal layer on a thermoelectric hydrogel with the redox pair Fe(CN)63−/Fe(CN)64−. The smart design of using the oxidation of pyrogallic acid by Fe(CN)63− to construct the photothermal layer for photo‐to‐heat conversion protected the redox couple of the thermogalvanic ion pair from ultraviolet damage, as well as triggered the formation of an interlocking structure at the interface of the photothermal layer and the thermoelectric hydrogel. The as‐prepared PTEH‐Interlocking has shown a high Seebeck coefficient and rapid heat transfer, boosting the photo‐thermo‐electric conversion. As a demonstration of a practical application, the PTEH‐Interlocking cells are successfully used as the energy supply for a mechanical sensor.
