摘要：

A new copolymer PBDTP-DTBT based on benzothiadiazole and alkylphenyl substituted benzodithiophene is synthesized and characterized. The correlation of the evolution of the morphology and photovoltaic performance is investigated. The power conversion efficiency of the polymer solar cells based on PBDTP-DTBT/PC71BM (1:1.5, w/w) reaches up to 8.07%, under the irradiation of AM 1.5G, 100 mW/cm2.
