Abstract
We report a novel diindenothieno[2,3-b]thiophene ladder-type hexacyclic arene for constructing a donor-acceptor copolymer PDITTDTBT. A device based on PDITTDTBT:PC(71)BM exhibited a high V(oc) of 0.92 V with an impressive PCE of 5.8%, while a PDITTDTBT:DMPCBA-based device showed an extra high V(oc) of 1.14 V.
摘要
我们报告了一种新型的二茚并[2,3-b]噻吩梯形六环芳烃，用于构建给体-受体共聚物 PDITTDTBT。基于 PDITTDTBT:PC(71)BM 的器件表现出 0.92 V 的高开路电压（V(oc)）和令人印象深刻的 5.8%的光电转换效率（PCE），而基于 PDITTDTBT:DMPCBA 的器件则表现出 1.14 V 的超高开路电压。
