Rylene diimide-based n-type organic semiconductors possess several advantages over traditional materials, such as structural diversity, facile chemical modification, and tunable optical and electronic properties. Rylene diimides are widely used as electron acceptors in organic solar cells (OSCs), with power conversion efficiencies of >11%. Recent studies have revealed that several rylene diimide acceptors show unique properties, such as efficient charge separation under negligible driving force and triplet excitons. This review summarizes the structural evolution of rylene diimide acceptors associated with an efficiency enhancement from 1% to 10%, aiming to extract effective design strategies and propose future perspectives and opportunities.

相对于传统材料，基于二甲亚砜的n型有机半导体具有多种优势，例如结构多样性，易于化学修饰以及可调节的光学和电子特性。萘二甲酰亚胺被广泛用作有机太阳能电池（OSC）中的电子受体，功率转换效率> 11％。最近的研究表明，几种萘二甲酰亚胺受体具有独特的性能，例如在可忽略的驱动力和三重态激子的作用下进行有效的电荷分离。这篇综述总结了与效率提高从1％到10％相关的Rylene diimide受体的结构演变，旨在提取有效的设计策略并提出未来的观点和机会。
