Commercialization of Perovskite solar cells as a clean energy source can augment the reduction of carbon footprint. CsPbI3, a well-known perovskite material, has been synthesized in ambient air and high-humidity conditions and utilized as the active layer in a perovskite solar cell. The rest of the solar cell layers have been sputter-deposited. This solar cell with a p-i-n configuration ITO/NiOx/CsPbI3/ZnO/Au exhibited a champion efficiency of 3.7%. Nonetheless, lead incorporation in the conventional Pb-cation-based perovskites poses an environmental threat. The physical proximity of living organisms to lead point sources exhibits a wide spectrum of negative consequences. In this study, we have also explored the photovoltaic performance of the Cs3Sb2I9 as an absorber using SCAPS-1D software. A planar, regular architecture with device configuration of FTO/TiO2/ Cs3Sb2I9/NiOx/Au has been proposed and numerically simulated. The best-optimized device yielded a maximum power conversion efficiency of 17.49%, open-circuit voltage Voc of 1.4 V, short-circuit current Jsc of 15.33 mA/cm2 , and fill factor FF of 80.95%.
