- Abstract
- An alternating copolymer of thiophene and thienothiophene with a cyanoacrylate group conjugated side chain was designed and synthesized. The structure and property of the main chain donor-side chain acceptor orthogonal copolymer was fully characterized. Through this unique structure of a copolymer, the electronic property and light absorption range were effectively tuned. The structure characteristics of an orthogonally conjugated polymer were also studied by molecular simulation. The polymer was used as donor in polymer solar cells. The device based on CNIT/PC71BM demonstrates a power conversion efficiency of 1.21% with a high J(sc) of 6.51 mA cm(-2) under the illumination of AM 15.G, 100 mW cm(-2). (C) 2015 Elsevier B.V.
