The organic–inorganic hybrid perovskite solar cells (PSCs) have demonstrated their unprecedented high efficiency and potential for commercialization. The volatile organic components in the hybrid perovskite crystal structure are still a big challenge for long‐term stabilities. Recently, inorganic CsPbI 3 perovskite has attracted much attention because of its superior chemical stability over the prevailing hybrid organic–inorganic perovskite and the most suitable band gap among all‐inorganic perovskites. Nevertheless, CsPbI 3 suffers from phase instability and low photovoltaic (PV) performance due to its undesirable tolerant factor. Much research effort has been devoted into stabilization of CsPbI 3 . In this perspective, we review the recent progress on chemical engineering processes for the stabilization of inorganic CsPbI 3 perovskite for high‐efficiency PVs. We also discuss the importance of understanding mechanism behind stabilization of CsPbI 3 perovskite film and the development of inorganic CsPbI 3 ‐based highly efficient and stable PSCs.
