英文摘要	A new conjugated polymer (PBFZ-OP) based on meta-alkoxy-phenyl-substituted benzodithiophene (BDT-m- OP) and difluorobenzotriazole (FBTZ) was designed and synthesized for application as a donor material in non-fullerene polymer solar cells (PSCs). The polymer exhibits a strong absorption in the range of 300-620 nm with a wide bandgap of 1.99 eV, which is complementary to that of the small molecule acceptor ITIC. Meanwhile, it also possesses a deeper HOMO energy level of -5.33 eV and a higher hole mobility of 7.28 x 10(-4) cm(2) V-1 s(-1). The PSCs based on PBFZ-OP: ITIC showed a higher power conversion efficiency (PCE) of 10.5% with a V-oc of 0.91 V, J(sc) of 18.7 mA cm(-2), and FF of 61.8% in comparison with the PCE of 5.5% with a V-oc of 0.73 V, J(sc) of 13.1 mA cm(-2), and FF of 57.8% for J52-based PSCs. The results indicate that PBFZ-OP is a promising wide bandgap polymer donor for the photovoltaic application in non-fullerene PSCs.
