摘要：

Two novel naphtho[1,2-c:5,6-c]bis(1,2,5-thiadiazole) and alkoxylphenyl substituted benzodithiophene based copolymers were developed as the donor materials for polymer solar cells. The resulting copolymers exhibit broad absorption bands in the range of 500-800 nm in thin films and deep highest occupied molecular orbital energy levels of -5.39 eV and -5.36 eV, respectively. The best device performance was achieved by P1, with an open-circuit voltage of 0.85 V, a short-circuit current density of 8.65 mA.cm(-2), a fill factor of 37.8%, and a power conversion efficiency of 2.78%.
