Lead toxicity is a barrier to the widespread commercial manufacture of lead halide perovskites and their use in solar photovoltaic (PV) devices. Eco-friendly lead-free perovskite cells (PSCs) have been developed using certain unique non- or low-toxic materials. In this context, Sn-based identified as promising substitutes for Pb-based due similar characteristics. However, suffer from chemical instability, which affects performance PSCs. This study employs theoretical simulations identify...
Perovskite solar cells (PSCs) have become a possible alternative to traditional photovoltaic devices for their high performance, low cost, and ease of fabrication. Here in this study, the SCAPS-1D simulator numerically simulates optimizes CsPbBr
