Random Donor-Acceptor configuration structure of semiconducting polymer for flexible, efficient and green-solvent processable solar cells |
| 초록 |
Optical and morphology, mechanical properties have a correlation with the configuration of polymer structure. In this study, Thiophene is introduced into the backbone in a regular (PffBT-T4) or random (PffBT-RT4) to determine whether semiconductor polymers are suitable for solar cells.. As a result of the microstructure analysis, PffBT-RT4 shows π- π stacking distance shorter than PffBT-T4. Besides, PffBt-RT4 have a higher power conversion efficiency (PCE; 8.84%) than PffBT-T4 (7.25%) because short distances benefit charge transport. In addition, the PffBT-RT4 shows performance in green solvent without additives (7.23%). In addition, PffBT-RT4 are much more stable during bending cycles than PffBT-T4. Therefore, this study demonstrates that the random arrangement is a promising strategy for efficient and green solvent processable solar cells. |
