摘要：

We developed and synthesized two novel polymeric semiconductor materials containing thienopyrrolodione (TPD) units, with one of the polymers also containing thiophene (T) units and the other containing bi-thiophene (BT) units, and denoted as TPD-T and TPD-BT, respectively. TPD-T and TPD-BT were studied for bulk heterojunction organic solar cells as blends with [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM). The TPD-T-based device exhibited considerably better photovoltaic performances, with a power conversion efficiency of 2.51%, in contrast to the 1.63% value for the TPD-BT-based device. According to atomic force microscope images of the TPD-BT:PC71BM and TPD-T:PC71BM blend films, the latter showed more nanoscale phase aggregation, explaining its better photovoltaic properties.
