The purpose of this project is to develop an innovative approach to explore and synthesize high-quality all-inorganic tin-based halide perovskite quantum dots for solar cells. In 2021, the defect formation mechanism was evaluated by density functional theory, and the synthesis parameters, especially the effect of capping agent on the properties of perovskite quantum dots was investigated. Introducing a small amount of zwitterionic phosphatidylcholine in the reaction was found to be important for regulating the growth kinetics of CsSnX3 perovskite quantum dots, which otherwise merely leads to the formation of large-sized powders.

本项目的目的是开发一种创新的方法来探索和合成高质量的全无机锡基钙钛矿太阳能电池量子点。2021年，利用密度泛函理论研究了钙钛矿型量子点的缺陷形成机理，研究了合成参数，特别是封顶剂对钙钛矿型量子点性能的影响。在反应中引入少量的两性磷脂酰胆碱对于调节CsSnX3钙钛矿量子点的生长动力学是重要的，否则只会导致大尺寸粉末的形成。
