Abstract

The high stability and low toxicity of bismuth-based perovskite materials can overcome current issues of lead-based perovskite solar cells (PSCs). In this study, a stable 2-amino-4-picoline (2-4py)-based bismuth perovskite material [(C6H9N2)BiI4] was developed, which has a low band gap and high stability. A one-step solution spin-coating method was used to prepare (C6H9N2)BiI4 film as the light-absorbing layer. The electron transport layers were composed of compact TiO2 (c-TiO2) and mesoporous TiO2 (mes-TiO2). Measurements by UV–vis and time-resolved photoluminescence showed that the band gap of (C6H9N2)BiI4 film was 2.0 eV and the fluorescence lifetime was 21.58 ns. The materials were assembled into a device, and comparative experimental results showed that the highest power conversion efficiency of fluorine-doped SnO2 (FTO)/c-TiO2 + mes-TiO2/(C6H9N2)BiI4/Spiro-OMeTAD/Au was 0.0328%. Although the efficiency of the current device was low, the (C6H9N2)BiI4 material exhibited excellent stability in hot and wet conditions. This indicates that (C6H9N2)BiI4 has potential for use in highly stable solar cells. [ABSTRACT FROM AUTHOR]

135. Design and analysis of underwater power generation characteristics of deflected double-stator switched reluctance generator.

Abstract

The Deflectable double-stator Switched Reluctance Generator (DSRG) has the advantages of simple structure, small volume and multi-dimensional operation. The DSRG and propeller are combined into the application of underwater power generation. With the help of the deflect ability of the generator, the efficiency is improved. Due to the uncertainty of ocean current direction and the structure of switched reluctance generator, the torque ripple is one of the important factors damaging the underwater generator. In order to effectively suppress the influence of torque ripple caused by generator operation, a method of adding pole shoes on the pole side of outer stator is proposed, so as to reduce the torque ripple. The propulsion structure running at different deflection angles is simulated. The torque and speed obtained before and after pole shoe optimization are input into the propeller model. The pressure and speed characteristics of the corresponding blade structure are simulated to verify the effect of optimization and the effectiveness of the power generation system.
