摘      要：This review summarized the recent progress of highly efficient wide bandgap(WBG) donor polymers and their applications in non-fullerene polymer solar cells(NF-PSCs). A brief introduction of the background of WBG donor polymer developments was given. Then the research progress of the reported WBG donor polymers by classification of D-type and DààA type molecular backbones was reviewed. The resulting structure-property correlations of the WBG donor polymers were also discussed to highlight the importance of chemical modifications, which have promoted the great progress of NF-PSC field. Finally,an outlook for future innovations of WBG donor polymers and their NF-PSCs was provided.
