Abstract:The lead toxicity and instability of conventional all‐inorganic lead halide perovskites hinder the production of efficient and stable nontoxic perovskite solar cells (PSCs), which prompts the search for viable nonleaded substitutes for photovoltaic (PV) applications. The present study investigates the optoelectronic characteristics of proposed lead‐free orthorhombic perovskites KSn1−xGexI3 (x = 0, 0.5, 1) via first‐principle density functional theory (DFT), to get an insight into their PV applicability.
