Perovskite solar cells have recently achieved photo-electric conversion efficiency over 19% showing a promising future for a cost-competitive potovoltaic technology. However, the study of perovskite solar cells' stability didn't catch up with the step of efficiency's process, which is the key issue for commercial application of perovskite solar cells. This review discussed the basic issues of the perovskite solar cells' stability under different circumstances, such as oxygen and moisture, UV light, solution process (solvents, solutes, additives), and temperature etc. and summarized how to control the perovskite solar cells' stability under the conditions above. The purpose is to provide a better understanding about perovskite solar cells'stability and the methods to increase the stability of perovskite solar cells under different circumstances.

Key words: perovskite solar cells, high efficiency, chemical stability, circumstances, control
