有机太阳能电池（OSCs）凭借低成本、轻量化、柔性可加工等优势，在光伏领域具有广阔应用前景，但传统阴极界面层（CILs）存在厚度高导致的电荷传输阻力增加、复合损耗加剧及能量转换效率（PCE）下降等问题。因此，开发具有优异厚度不敏感的CILs至关重要，而n-型自掺杂CILs已成为提高电荷提取、降低界面损耗和实现对厚度不敏感的OSCs的一种有效的方法。
近日，南昌航空大学周丹教授、南昌大学谌烈教授和豫章师范学院徐镇田博士等人在国际知名期刊《ACS Energy Letters》发表综述，系统综述了n-型自掺杂阴极界面层的研究进展。

本 文 要 点
1)首先，总结了有机太阳能电池的应用和工作原理，阐明了n-型自掺杂CILs的工作机制以及近年来所取得的研究进展。
2)其次，系统地对n-型自掺杂的小分子与聚合物CILs进行了分类，并凝练了关键优化策略（分子设计、掺杂浓度控制、界面工程），以减轻厚度引起的效率损失。
3)最后，本综述概述了OSCs的挑战（可扩展制造、稳定性、与非富勒烯受体的集成），并概述了克服厚度限制的n-型自掺杂CILs，强调了其大规模生产光伏潜力。
本综述为开发厚度不敏感、高效、稳定有机太阳能电池提供了理论依据和设计指导。
