Recent progress in wide bandgap conjugated polymer donors for high-performance nonfullerene organic photovoltaics

Abstract

During the last five years, the tremendous progress in the community of polymer solar cells (PSCs) has attracted extensive attention on the emerging technology for exploiting renewable energy. Owing to the excellent optoelectronic features as well as outstanding manufacturability in film deposition, wide bandgap (WBG) polymer donors rose as a dominating component in bulk heterojunction layer, so that correlative review focusing on molecular design, aggregation behavior and photovoltaic property was in emergent demand. In this Feature Article, we summarize our recent efforts in developing WBG polymer donors, understanding charge separation and non-radiative recombination energy loss for high-performance non-fullerene (NF) PSCs. We also discuss opportunities and challenges towards the realization of commercialization based on WBG polymer donors in NF PSCs.
