摘      要：A series of low band gap terpolymers based on 4,8-bis（5-（2-ethylhexyl）thiophen-2-yl）benzo[l,2-b：4,5- b＇]dithiophene （BDTr） and diketopyrrolopyrrole （DPP） with varied solubilizing groups （i.e., tert- butoxycarbonyl, t-Boc and 2-octyldodecyl） are developed as electron donors for bulk heterojunction （BHJ） polymer solar cells （PSCs）. The results reveal that the one with 50% t-Boc concentration （P3） performs better than the other terpolymers used in this study in conventional PSC devices with a power conversion efficiency of 2.92%.
