摘　　要：近几年,钙钛矿太阳电池(perovskite solar cells,PSCs)成为光伏领域研究的热点.自2009年,在短短10年时间内PSCs效率就从3. 8%迅速提升至24. 2%,其效率几乎可以与传统硅电池相媲美,然而较差的稳定性阻碍了PSCs实用化的进程.PSCs的稳定性主要包括钙钛矿材料及其他功能层材料的稳定性,因此,重点探讨了水、氧、光、热等环境因素对钙钛矿材料以及PSCs稳定性的影响规律,以及导致其性能衰退的主要原因.同时,分析并总结了如何利用钙钛矿组分及结构优化、界面修饰、电荷传输层材料改进、封装等方式来提升PCSs稳定性的可行性.In recent years,perovskite solar cells( PSCs) have become a research focus in the field of photovoltaics. The efficiency of PSCs has increased from 3. 8%( in 2009) to 24. 2%( in 2019) in only a few years,which can be compared with commercialized thin film solar cells based on Si;however,the instability of the PSCs hinders its wide application. The stability of PSCs mainly includes the stability of perovskites and other functional layer materials. This review focused on the factors limiting the stability of PSCs,such as humidity,oxygen,light,and heat. At the same time,recent strategies were summarized to overcome stability such as perovskite composition and structure optimization,interface modification,charge transport material improvement,and encapsulation.
