Organic solar cells (OSCs) have acquired dramatic progresses during the past several years due to low-cost, light weight, mechanical flexibility, and printable fabrication. Simultaneously, the nonfullerene acceptors (NFAs) exert significant influence on widening the absorption and enhancing the stability and power conversion effi-ciency (PCE) of OSCs. Consequently, NFAs have attracted increasing attention on account of some inherent superiorities. The PCE of OSCs has been elevated to over 20%. Small-molecule and polymer NFAs play a crucial role in OSCs. A summary based on NFAs in OSCs has been concluded. Firstly, the development and working principles of NFAs-based OSCs are briefly summarized; secondly, the characteristics of small molecule and polymer NFAs are introduced. Finally, the evolution and prospects of NFAs are also discussed.
