In recent years, due to the instability of perovskite, the road of commercialization is very difficult. First of all, this paper summarizes the two important factors affecting the stability, namely intrinsic and chemical instability, which can be specifically water, oxygen, temperature, light and so on. Secondly, the main methods to improve the stability of perovskite materials are summarized, including internal optimization and external optimization, such as crystallization regulation, doping control, additive addition and so on. Finally, the summary and Prospect of practical application in this field are given.
