摘      要：The power conversion efficiencies(PCEs)of single-junction organic solar cells(OSCs)have surpassed 19%,owing to the emerging Y-series nonfullerene acceptors(NFAs).Undoubtedly,the power and flexibility of chemical design has been a strong driver for this rapid efficiency improvement in the OSC *** the course of the past 3 years,a variety of modifications have been made to the structure of the Y6 acceptor,and a large number of Y-series NFAs have been reported to further improve ***,we present our insights into the rationale behind the Y6 acceptor and discuss the design principles toward high-performance Y-series *** is clear that structural modifications through choice of heteroatom,soluble chains,πspacers,central cores,and end groups alter the material characteristics and properties,contributing to distinctive photovoltaic ***,we analyze various design strategies of Y-series-containing materials,including polymerized small-molecule acceptors(PSMA),non-fused-ring acceptors(NFRA),and all-fused-ring acceptors(AFRA).This review is expected to be of value in providing effective molecular design strategies for high-performance NFAs in future innovations.
