Abstract

Addressing the imperative need to eliminate hazardous lead from the widely used metal halide perovskite photovoltaics (PPVs), the search for efficient and stable lead‐free perovskite alternatives remains pivotal. Herein, a performance analysis of lead‐free, all‐inorganic cesium tin triiodide (CsSnI3)‐based PPVs with a graphene oxide hole transporting layer using solar cell capacitance simulator is presented. Various parameters to optimize the PPV performance, including CsSnI3 layer thickness, defect density, interface defect, parasitic resistances, and working temperature are explored. The optimization process yielded remarkable results, with open‐circuit voltage of 0.87 V, short‐circuit current density of 32.55 mA cm−2, fill factor of 77.59%, and power conversion efficiency of 22.15%. The proposed device structure and parameters not only contribute to the advancement of these experimental works but also offer a novel strategy for the structural optimization of lead‐free PPVs, thereby paving new avenues for future research in this area.

Abstract

Hole transport material (HTM) plays an essential function in perovskite solar cells (PSCs). The utilization of polymer materials has been studied but with little effectiveness, typically resulting in a lower conversion efficiency than Spiro-OMeTAD. Spiro-OMeTAD requires comparable dopants and additives, which is a source of perovskite instability. Poor stability and higher design costs of spiro-OMeTAD require an alternatives HTM. In this study, a numerical simulation analysis on the PSCs performance with graphene oxide (GO) as HTM is conducted using a SCAPS-1D. The simulation was performed to evaluate the effect of various parameters on the output of devices, such as perovskite thickness, HTM thickness, and interface defect. The optimized result shows short-circuit current density (JSC) of 24.44 mA.cm-2, open- circuit voltage (VOC) of 1.04 V, fill factor (FF) of 73.12%, and power conversion efficiency (PCE) of 18.53%. This result indicates that it is feasible to use GO as HTM as a potential alternative for the costly Spiro-OMeTAD. [ABSTRACT FROM AUTHOR]
