Abstract : Alkylthiothieyl substituted benzothiophene (BDT) and alkoxycarbonyl cyanovinyl modified thienothiophene (TT) were copolymerized to obtain a new low band gap copolymer PBDTTT-S-CN with a efficiency of 7.00%. Abstract : Alkylthiothieyl substituted benzothiophene (BDT) and alkoxycarbonyl cyanovinyl modified thienothiophene (TT) were copolymerized to obtain a new two dimensional low band gap polymer PBDTTT-S-CN, which exhibited a promising efficiency of 7.0% in organic solar cells.
