| 英文摘要 | In this work, a new D-A copolymer based on m-alkoxyphenyl substituted benzodithiophene (BDT-m-OP) as donor unit and benzo[1,2-c:4,5,c']dithiophene-4,8-dione (BDD) as acceptor unit was designed and synthesized, in which selenophene unit as pi-conjugated spacer was incorporated into the polymer backbone to broaden the absorption spectrum, enhance the charge transport properties, and even improve the photovoltaic properties. Compared with PBPD-Th with thiophene as pi-conjugated spacer, PBPD-Se exhibits an evidently extended absorption spectrum and an enhanced hole mobility with a slightly raised HOMO energy level. The PBPD-Se:PC71BM-based PSCs exhibits a. significantly improved PCE of 9.8% with an enhanced J(sc) of 14.9 mA cm(-2) and a slightly lower V-oc of 0.90 V in comparison with a PCE of 8.4% with a V-oc of 0.95 V and a J(sc) of 12.4 mA cm(-2) for PBPD-Th:PC71BM-based devices. These results indicate that the rational selection of pi-conjugated spacer in the D-A copolymer backbone is very essential to achieve high efficiency PSCs. |
