Organic–inorganic halide perovskite solar cells (PSCs) have recently attracted much attention with the recent certified power conversion efficiency (PCE) record exceeding 24%. To date, many approaches have been developed for producing high‐performance PSCs, in which the application of multifunctional molecules plays an important role. The multifunctional molecules can modify the morphology of perovskite films and/or passivate the surface defects through interactions with the perovskites' boundaries and/or the charge carrier extraction interfaces. As a result, both the PCEs and the stability of PSCs are improved. The recent progress in the development of multifunctional molecules‐incorporated PSCs is reviewed. The importance of further understanding of the role of the multifunctional molecules in the perovskite film formation process and defect passivation mechanism is discussed. Further research in terms of multifunctional molecules can help to develop high‐performance devices with long‐term stability for future practical applications of PSCs.

钙钛矿太阳能电池多功能分子研究进展

有机-无机卤化物钙钛矿太阳能电池（PSC）最近备受关注，最近的认证功率转换效率（PCE）记录超过24％。迄今为止，已开发出许多生产高性能PSC的方法，其中多功能分子的应用起着重要作用。多功能分子可以通过与钙钛矿的边界和/或电荷载流子提取界面的相互作用来改变钙钛矿膜的形态和/或钝化表面缺陷。结果，PCE和PSC的稳定性均得到改善。综述了结合多功能分子的PSCs的最新进展。讨论了进一步了解多功能分子在钙钛矿膜形成过程中的作用和缺陷钝化机理的重要性。关于多功能分子的进一步研究可以帮助开发具有长期稳定性的高性能器件，以用于PSC的未来实际应用。
