摘　　要：空穴传输材料的性能直接影响钙钛矿太阳电池中空穴在电池中的传输和电子-空穴的复合,从而决定电池性能。螺环结构特殊的正交分子构象使分子易于在钙钛矿薄膜上形成良好的接触、具有均匀的电荷传输特性、较高的玻璃化转变温度等优点,该材料已广泛作为高效空穴传输材料骨架单元应用于钙钛矿太阳电池。本论文概述了小分子螺环空穴传输材料的研究进展,主要从分子末端官能团优化和螺环核调控两个方面总结了分子结构变化对材料光物理、电化学、热稳定性、空穴传输特性及在钙钛矿太阳电池中的性能等的影响,同时本论文也对该领域的发展和高性能螺环空穴传输材料的发展和研究趋势进行了预测。The performance of hole transport materials significantly influences the hole transport and electron-hole recombination in perovskite solar cells,which in turn affects the cells'efficiency.The spiro-type structure has a unique orthogonal molecular conformation.This makes the molecules form good contact on the perovskite film easily.It also leads to uniform charge transport characteristics and a higher glass transition temperature.This material has been widely used as a highly efficient hole transport material skeleton unit in perovskite solar cells.This paper summarizes the advancements in spiro-type hole transport materials,focusing primarily on the optimization of terminal functional groups and spiro-type core regulation in spiro-type small molecule materials.It discusses how changes in molecular structure impact the material’s photophysics,electrochemistry,thermal stability,hole transport characteristics,and overall performance in perovskite solar cells.Additionally,this paper forecasts future developments in this area,examining the trends and research directions of high-performance spiral-type hole transport materials.
