A donor–acceptor-type conjugated alternating copolymer (PBDT–DFBSe) consisting of benzodithiophene (BDT) and a fluorinated 2,1,3-benzoselenadiazole derivative (DFBSe) is synthesized. The optical, electrochemical, and photovoltaic properties of PBDT–DFBSe are compared with those of its non-fluorinated analog, PBDT–BSe, which is composed of BDT and 2,1,3-benzoselenadiazole (BSe). Bulk heterojunction organic photovoltaic cells are fabricated using the polymers.
