外文摘要：In the last few years,organic solar cells(OSCs)have made significant progress in photovoltaic performance,mainly due to the innova-tive development of active layer materials,especially Y-series and related derivatives as acceptors which have become the key factor that boosts the power conversion efficiency.Recently,to achieve high-performance OSCs,an emerging molecular design strategy of applying flexible alkyl units as linkers to construct non-fully conjugated acceptors has been developed and addressed great attention.This review highlights the non-fully conjugated photovoltaic materials with Y-series backbone that enable high-performance OSCs.Impressive OSCs have been achieved by some representative non-fully conjugated material systems.The related molecular design strategies are discussed in detail.Finally,a brief summary and future prospect are provided in advancing the non-fully conjugated photovoltaic materials with Y-series backbone towards the brighter future.
