摘要

A novel fluorine-containing benzo[1,2-b:4,5-b']dithiophene (BDT) derivative (BDTPF) was designed to construct a donor-acceptor (D-A)-structured polymer (PBDTPF-DTBT) with the electron-withdrawing unit 4,7-di(4-(2-ethylhexyl)-2-thienyl)-2,1,3-benzothiadiazole (DTBT). The resulting polymer exhibits a broad absorption spectrum, relatively low lying HOMO energy level (-5.39 eV) and a good film-forming ability. The field-effect mobility of PBDTPF-DTBT is 0.034 cm(2) V-1 s(-1). Bulk heterojunction organic solar cells (OSCs) based on PBDTPF-DTBT and PC71BM were prepared and showed a good photovoltaic performance with power conversion efficiency (PCE) of 7.02%. This work demonstrates that a BDT unit with fluorinated alkoxyphenyl side chains is a promising candidate as an electron-rich building block for high performance solution-processed OSCs.
