Develop of TPD-based Polymers for OPV Applications as Donor Materials |
| 초록 |
Two conjugated thienopyrrolodione-thiophene-vinyl-thiophene (TPD-TVT)-based polymers, with one of them having an additional cyano (CN) group attached to the TVT unit, were designed and synthesized and shown to be efficient donor materials for OPV applications. Both TPD-TVT and TPD-TVTCN showed good thermal stability and appropriate solubility in chlorinated solvents, but they exhibited quite different opto-electrochemical characteristics. Also, compared to TPD-TVTCN, the TPD-TVT donor polymer displayed less aggregation, and formed a better-mixed blend with PC71BM. Solar cells we made also showed better device performances, which we attributed to more nanoscale phase aggregation. |
