| 英文摘要 | Two new D-A alternating copolymers, PBDFFBT and PBDTFBT, featuring a fluorinated benzothiazole (BT) electron-acceptor unit and the electron-donor segments of benzo[1,2-b:4,5-b'] difuran (BDF) or benzo[1,2-b:4,5-b']dithiophene (BDT), were prepared by a standard Stille cross-coupling reaction. The resulting copolymers were characterized by TGA, GPC, UV-vis absorption spectroscopy and cyclic voltammetry measurements. PBDFFBT and PBDTFBT show good film forming properties. Bulk heterojunction polymer photovoltaic devices based on an active layer of the electron donor copolymers (PBDFFBT and PBDTFBT), blended with an electron acceptor [6,6]-phenyl-C-71 butyric acid methyl ester (PC71BM) in three weight ratios of 1 : 1, 1 : 2 and 1 : 3 were investigated. The devices with the configuration of ITO/PEDOT:PSS/polymer:PC71BM/Ca/Al demonstrated promising power conversion efficiencies of 3.3% for PBDFFBT:PC71BM (1 : 3, w/w) and 4.0% for PBDTFBT:PC71BM (1 : 2, w/w) under the illumination of AM 1.5, 100 mW cm(-2). |
