摘　　要：目前钙钛矿太阳能电池(PSCs)的性能已经可以和晶硅太阳能电池相媲美,但是其器件稳定性较差,不利于产业化应用。介绍了造成钙钛矿纳米晶不稳定的因素以及提高对应太阳能电池稳定性的主要策略,调研了近几年有机硅在PSC中的研究现状,详细探讨了硅烷偶联剂、硅树脂以及其他有机硅分子对钙钛矿薄膜的性质(如微观形貌、缺陷态密度、载流子输运以及离子迁移等)与电池器件性能(如光电转化效率和稳定性等)的影响机制,最后,展望了自交联有机硅材料在高效、稳定PSC中的发展趋势,以期为加快推进PSC产业化提供借鉴。At present, the performances of perovskite solar cells(PSCs)are comparable to that of crystalline silicon solar cells, but their relatively poor stabilities are not conducive to industrial application. In this paper, the factors causing the instabilities of perovskite nanocrystals and the main strategies to improve the stability of corresponding solar cells are introduced, while the latest research progresses of organosilicon in PSCs are evaluated. The influence mechanism of silane coupling agent, silicone resin and other organosilicon molecules on the properties of perovskite films(such as morphology,trap state density, carrier transport and ion migration, etc.)and the performances of devices(such as power conversion efficiency and stability, etc.)will be discussed in detail. Finally, the development trend of self-crosslinked organosilicon materials in efficient and stable PSCs are prospected, aiming to provide reference for accelerating the industrialization of PSCs.
