Abstract :
In recent years, perovskite solar cells (PSCs) have been considered one of the most promising photovoltaic technologies due to their affordability and excellent performance. However, perovskites are sensitive to parameters such as humidity, oxygen, temperature, and electrical bias. Changes in the composition and structure of materials from the precursor to the resulting perovskite lead to various defects. During long-term operation, these defects often act as the initiation of degradation to deteriorate PSC performance. A series of methods have been developed to prevent contact between the corrosive environment and perovskite. For this purpose, various techniques have been designed to control these parameters, which include removing corrosion sites during construction, eliminating corrosion sites during machine operation, and preventing contact between the corrosive environment and perovskite. In this review, the lifetime of PSC is discussed from the point of view of corrosion science. Finally, the use of a series of anti-corrosion strategies (passivation, surface coating, machining) in corrosion science significantly increases the stability of perovskite cells.
