The photovoltaic industry has witnessed a remarkable breakthrough with the advent of lead halide perovskite solar cells (LHPSCs), which have achieved outstanding power conversion efficiencies (PCEs); 25% in single-junction and 29% in monolithic tandem configurations. Despite this progress, challenges such as poor long-term stability, phase degradation under light, heat, and moisture, and the toxicity of lead (Pb) remain significant obstacles to commercial scalability and environmental safety.
