摘要

Nowadays,wide-bandgap (WBG) copolymers attract great attention in the field of organic photovoltaics [1].They are ideal electron-donating partners for low-bandgap small molecule acceptors [2-12].With good energy levels matching,the blend of WBG copolymer donor and small molecule acceptor can harvest most of the sunlight and deliver high power conversion efficiencies (PCEs) in solar cells.
