Publication date: Available online 21 March 2019Source: Chinese Chemical LettersAuthor(s): Xiaopeng Xu, Guangjun Zhang, Ying Li, Qiang PengABSTRACTThis 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 D-A 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.Graphical abstractThe recent progress of wide bandgap (WBG) donor polymers for non-fullerene polymer solar cells (NF-PSCs) were reviewed in detail, which was classified by D-type and D-A type molecular backbones to discuss the related structure-property correlations and put forward an outlook for future innovations.
