During the past decade, bulk heterojunction (BHJ) polymer solar cells (PSCs) have been the focus of both scientific research and industrial application, because of their potential applications in large area, lightweight, flexible photovoltaic devices through low-cost solution-processable techniques. We designed and synthesized a of D-π-A copolymer based on quinacridone (QC) donor unit and benzooxadiazole (BO) acceptor unit bridged thienothiophene. Thienothiophene (TT) bridge is propitious to enhance both hole mobility and photovoltaic performance of the D-π-A copolymers. In this study, we synthesized a new thieno[3,2-b]thiophene bridged D-π-A copolymer, PQCDttBO, using suzuki coupling reaction. The synthesized polymer is showed physical, optical, electrochemical and photovoltaic properties. |
