Summary: | Perovskite solar cells (PSCs) have attracted tremendous interest because of their rushing improvement in power conversion efficiency (PCE) from the initial 3.8% to the most recently certified 25.2%. Despite the high efficiency of photovoltaic prospects, organic-inorganic hybrid perovskite materials with the requisite organic components are very sensitive and heterolytic under heat and humidity conditions. One of the promising methods to prepare inorganic perovskite solar cells (I–PSCs) by completely replacing the A-site organic cations in ABX3 structure has developed rapidly due to their excellent thermal and environmental stability. However, the phase instability of inorganic perovskite, especially for α‐CsPbI3, has been the bottleneck hindering their development in ambient conditions. Doping with new components is regarded as an effective method to assist the formation of high‐quality and stable inorganic perovskite films. The Gold-Schmidt tolerance factor t optimization or the intramolecular interaction between perovskite precursors with the new components has a substantial influence on the crystallization kinetics and the structural stability, while simultaneously offering the enhanced carrier transport characteristics and surface tension. Here, we systematically summarize the most recent research progress of inorganic perovskite and discuss strategies to overcome the phase instability from the perspective of doping for the first time. We also outlined the doped system of perovskite derivatives and summarized the application of the doped inorganic perovskite for photovoltaic application. Finally, we focus on prospecting the challenges and future research directions to achieve super-stable inorganic perovskites and their photovoltaics.
