摘　　要：基于有机-无机杂化钙钛矿材料具有带隙可调、光吸收带宽、双极电荷传输性能好、电荷扩散长度长、溶液加工成本低等优点,钙钛矿太阳能电池受到研究人员的广泛关注。空穴传输材料作为钙钛矿太阳能电池的重要组成部分,对载流子的提取和运输、钙钛矿的结晶性、电池器件的稳定性和制作成本都有相当大的影响。本文介绍了近年来有机共轭小分子作为空穴传输材料的研究进展,特别是其分子结构对材料各项性能的调控作用,包括能级、空穴迁移率、成膜性以及器件的光电转换效率和长期稳定性等,以期为未来有机共轭小分子空穴传输材料的研发提供参考。Due to the adjustable band gap,broad absorption band,good charge transport property,long charge diffusion length,and low preparation cost,more and more attention has been focused on perovskite solar cells.As one of the most important components in perovskite solar cells,hole transport material has a considerable impact on the extraction and transport of carriers,the crystallinity of perovskite,the stability of cell device and the manufacturing cost.In this review,the research progress on the application of organic conjugation molecules as hole transport materials has been summarized,especially for the relationship between the chemical structure and the properties,including energy level,hole mobility,film morphology,photovoltaic performance,and the stability of the cell device.
