Synthesis and Characterization of New TPD-based Polymeric Semiconductors |
| 초록 |
We developed and synthesized two novel polymeric semiconductor materials containing 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). In other words, we successfully developed two novel photoactive -conjugated copolymers, TPD-T and TPD-BT, containing TPD units via a Stille coupling polymerization approach. The TPD-T device showed a power conversion efficiency of 2.51%, higher than the 1.63% value of the TPD-BT device, and this difference was attributed to their different nanoscale bulk morphologies and hole mobilities. |
