Abstract: In recent years, organic-inorganic hybrid perovskite solar cell (PSC) has become a highlight in the field of photovoltaic materials. As a new type of solar cell, the perovskite solar cell has been widely concerned by scientists all around the world. Recently, the power conversion efficiency (PCE) of PSC has been promoted to more than 21 % in laboratory. As is known to all, the poor stability of high efficiency devices is a stumbling block to the industrialization, and the research on how to improve the stability of perovskite solar cells has increased in recent years. This paper summarized the stability of the latest progress from perovskite as the absorbing light material was introduced into the solar cell research, focusing on two aspects about stability of material and device interface composition of perovskite solar cell. The interface stability of the whole cell was described with the stability of the physical and chemical properties of the CH3NH3PbI3 as the object. At last, the development course of perovskite solar cell was reviewed, and the stability of perovskite solar cell was summarized and the development direction of this field was also proposed from the point of view of practical application.
