The high performance of perovskite solar cells (PSCs) has been upgraded from 9.7% to 20.1 percent per year on average. However, no research has been done on the problem of durability, which limits the use of PSCs outside. The problem of perovskite deterioration and the durability of the perovskite device should be handled as soon as possible in order to ensure excellent repeatability and a long lifespan. High conversion efficiency PSCs. The fascinating research on stability would not be possible without it. Laboratory accomplishments cannot be translated to industrial or outdoor applications. In Basic knowledge of the degradation process of PSCs in order to enhance reliability. Various circumstances should be carefully investigated. The findings of a recent research are summarized in this review discusses the chemical stability of PSCs in respect to their surroundings (oxygen and moisture, for example).UV radiation, solution procedure, temperature, and so on) and the potential remedies.
