| 英文摘要 | To investigate the effect of the fluoride phenyl side-chains into quinoxaline (PQx) unit on the photovoltaic performances of polymers, we demonstrated the synthesis and characterization of two novel wide-bandgap (WBG) copolymers, PIDT-DTPQx and PIDT-DTFPQx, in which indacenodithiophene (IDT), 2,3-diphenylquinoxaline (PQx) (and/or 2,3-bis(4-fluorophenyl) quinoxaline (FPQx)) and thiophene (T) were used as the donor (D) unit, acceptor (A) unit and pi-bridge, respectively. Compared to the non-fluorine substituted PIDT-DTPQx, fluorine substituted PIDT-DTFPQx presents a deep HOMO energy level and a high hole mobility. Obviously, improved the V-oc, J(sc), and FF simultaneously, giving rise to overall efficiencies in the PIDT-DTFPQx/PC71BM-based PSCs. A highest PCE of 5.78% was obtained with a V-oc of 0.86 V, J(sc) of 10.84 mA cm(-2) and FF of 61.7% in the PIDT-DTFPQx/PC71BM-based PSCs, while PIDT-DTPQx based devices also demonstrated a PCE of 5.11%, under the illumination of AM 1.5G (100 mW cm(-2)). Note that these PCE values were achieved for PSCs without any extra treatments. Furthermore, these optimal devices have a film thickness of about 175 nm for the polymer/PC71BM-based active layers. The results provide that introduction of the fluorine atom into quinoxaline unit by side-chain engineering is one of the effective strategies to construct the promising polymer donor materials for future application of large-area polymer solar cells.
