Numerical Analysis and HTL Variation of CH3NH3SnI3 Based Perovskite Solar Cell Using SCAPS-1D

Abstract

Perovskite solar cells have shown success in photovoltaics but further improvements are needed Lead-based organic-inorganic hybrid perovskites have potential but toxicity issues prevent commercialization Scientists are working on an eco-friendly lead-free organic perovskite material This study proposes a lead-free perovskite solar cell with CH3NH3SnI3 absorber layer Cu2O as the best HTL output FTO as TCO and ZnO as ETL SCAPS software is used for optimization and performance optimization Different solar cell parameters such as absorber layer thickness doping concentration of the absorber layer defect density of the absorber layer and HTL and ETL thickness were examined in order to determine the ideal solar cell device With VOC 0 98 V Jsc 31 93 mA cm2 and FF 84 34 the maximum power conversion efficiency of 27 66 is achieved These modeling results could be useful in the development of low-cost highly effective perovskite solar cells
