Abstract Energy demand has dramatically increased globally, posing a serious risk of future energy crises. While various sources have been utilized, solar emerged as the most promising renewable option, convertible to electrical via cells. Among developed cells, perovskite cells (PSCs) recently received significant attentions due their simple fabrication, high performance, and cost‐effectiveness. In particular, lead (Pb) halide‐based PSCs achieved highest power conversion efficiency. However, despite excellent Pb are hindered by toxicity in structures. Consequently, researchers explored germanium (Ge) tin (Sn) halide materials for development Pb‐free (LFPSCs). The past few years seen rapid advancements numerical simulation LFPSCs using SCAPS software. These studies crucial developing with enhanced performance.
