摘要	In this article, two dithienosilole (DTS) and bithiazole (BTz) backboned donor-acceptor (D-A) copolymers with (poly{5-(5-(4,4-bis(2-ethylhexyl)-4H-silolo[3,2-b:4,5-b']dithiophen-2-yl)thiophen-2-yl)-4,4'-dinonyl-5'-(thiophen-2-yl)-2,2'-bithiazole} (PDTS-DTBTz)) and without (poly{5-(4,4-bis(2-ethylhexyl)-4H-silolo[3,2-b:4,5-b']dithiophen-2-yl)-4,4'-dinonyl-2,2'-bithiazole} (PDTS-BTz)) thiophene -bridge were synthesized to study the influence of thiophene -bridge on their photovoltaic performances. Both polymers show similar band gap, but polymer with thiophene -bridge (PDTS-DTBTz) has a higher molecular weight, narrower polydispersity index (PDI), more planar geometry, higher crystallinity, higher hole mobility, and better miscibility with fullerene (polymer solar cells (PSCs) acceptor). Although PDTS-BTz polymer based PSCs devices show higher open circuit voltage (V-oc), PDTS-DTBTz polymer does show higher power conversion efficiency (PCE) with improved short circuit current density (J(sc)) and fill factor (FF). The present results indicate that thiophene -bridge does contribute to the PSCs performances of dithienosilole and bithiazole backboned copolymer. (c) 2015 Wiley Periodicals, Inc.
