摘要: | High-molecular-weight conjugated polymer HD-PDFC-DTBT with N-(2-hexyldecyl)-3,6-difluorocarbazole as the donor unit, 5,6-bis(octyloxy)benzothiadiazole as the acceptor unit, and thiophene as the spacer is synthesized by Suzuki polycondensation. HD-PDFC-DTBT shows a large bandgap of 1.96 eV and a high hole mobility of 0.16 cm(2) V-1 s(-1). HD-PDFC-DTBT:PC71BM-based inverted polymer solar cells (PSCs) give a power conversion efficiency (PCE) of 7.39% with a V-oc of 0.93 V, a J(sc) of 14.11 mA cm(-2), and an FF of 0.56. |
