Powering the Future: Opportunities and Obstacles in Lead‐Halide Inorganic Perovskite Solar Cells

Abstract Efficiency, stability, and cost are crucial considerations in the development of photovoltaic technology for commercialization. Perovskite solar cells (PSCs) are a promising third‐generation photovoltaic technology due to their high efficiency and low‐cost potential. However, the stability of organohalide perovskites remains a significant challenge. Inorganic perovskites, based on CsPbX ₃ (X = Br − /I − ), have garnered attention for their excellent thermal stability and optoelectronic properties comparable to those of organohalide perovskites. Nevertheless, the development of inorganic perovskites faces several hurdles, including the need for high‐temperature annealing to achieve the photoactive…
