Perovskite solar cells (PSCs) are currently attracting a great deal of attention for their excellent photovoltaic properties, with a maximum photoelectric conversion efficiency (PCE) of 25.5%, comparable to that of silicon-based solar cells. However, PSCs suffer from energy level mismatch, a large number of defects in perovskite films, and easy decomposition under ultraviolet (UV) light, which greatly limit the industrial application of PSCs. Currently, quantum dot (QD) materials are widely used in PSCs due to their properties, such as quantum size effect and multi-exciton effect. In this review, we detail the application of QDs as an interfacial layer to PSCs to optimize the energy level alignment between two adjacent layers, facilitate charge and hole transport, and also effectively assist in the crystallization of perovskite films and passivate defects on the film surface.
钙钛矿太阳能电池（PSCs）目前因其优异的光伏性能而备受关注，其最大光电转换效率（PCE）为25.5%，与硅基太阳能电池相当。然而，PSCs存在能级不匹配、钙钛矿薄膜中大量缺陷以及在紫外（UV）光下易分解等问题，这极大地限制了PSCs的工业应用。目前，量子点（QD）材料因其量子尺寸效应和多激子效应等特性而被广泛应用于PSCs。在本综述中，我们详细阐述了量子点作为界面层在PSCs中的应用，以优化两个相邻层之间的能级排列，促进电荷和空穴传输，同时还能有效协助钙钛矿薄膜的结晶并钝化薄膜表面的缺陷。
