Lead halide perovskites have achieved remarkable power conversion efficiencies (PCE) of up to 26.1%. However, their instability against moisture and heat, along with toxicity concerns, limits their commercial viability. To address these challenges, we explored chalcogenide perovskites, specifically ABSe3 (where A = Ca, Ba, and B = Zr, Hf), as promising alternatives.
