Polymer electron acceptor materials have attracted significant attention due to their advantages such as adjustable energy levels and bandgaps,high absorption coefficients and excellent electrical and photovoltaic properties.Designing and synthesizing high-performance polymer electron acceptors have become one of the mainstream research topics of organic solar cells (OSCs).Due to the rapid development of polymer electron acceptors,the power conversion efficiencies (PCEs) of all-polymer solar cells (All-PSCs) have been greatly improved.The development of new polymer electron acceptors plays an important role in improving PCE.In this paper,the research progress of polymer electron acceptors based on imide structural units in recent years was reviewed,and the future development direction was prospected.
