摘要

Three copolymers, PFTpBt, PFbCNTpBt, and PFC6TpBt, which are based on dioctylfluorene, dithienylbenzothiadiazole, and thiophene derivatives with different functional groups, were synthesized via a Suzuki reaction. The copolymers were characterized by NMR, GPC, TGA, UVvis absorption, and electrochemical cyclic voltammetry. Thermogravimetric analysis showed that the copolymers exhibited good thermal stability. The optical, electrochemical, photovoltaic properties, and hole mobility of the copolymers were investigated and discussed. The polymer solar cell based on PFTpBt had the best performance, with a power conversion efficiency (PCE) of 2.17% under the illumination of AM 1.5, 100 mW/cm2.
