• We report a novel diindenothieno[2,3- b ]thiophene ladder-type hexacyclic arene for constructing a donoracceptor 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. A new diindenothieno[2,3- d ]thiophene-based donoracceptor copolymer PDITTDTBT was developed to achieve a high PCE of 5.8% with an extra high V oc .
