摘要

With growing environmental and economic concerns over fossil fuels, solar power has become an increasingly important renewable option. This study evaluates lead-free MASnIBr2 perovskite solar cells using COMSOL Multiphysics simulations, focusing on absorber thickness, bulk defect concentration, and interfacial passivation effects. Incorporation of a porous insulating contact (PIC) structure suppresses non-radiative recombination, increasing the power conversion efficiency (PCE) to 22.65%. After optimization, the perovskite–silicon tandem configuration attains current balance between subcells and delivers a PCE of 33.74%. These results indicate that MASnIBr₂ is a viable absorber for high-efficiency lead-free tandem photovoltaic devices.
