Diindenothieno[2,3-b]thiophene arene for efficient organic photovoltaics with an extra high open-circuit voltage of 1.14 ev

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:PC71BM exhibited a high Voc of 0.92 V with an impressive PCE of 5.8%, while a PDITTDTBT:DMPCBA-based device showed an extra high Voc of 1.14 V.
