英文摘要	two polythiophene derivatives using fluorine atoms and hexyl or hexyloxy group as electron-withdrawing and donating substituents have been synthesized. the introduction of fluorine atoms to the polythiophene backbones simultaneously lowers the homo and narrows the bandgap, and the stronger electron-donating ability of hexyloxy side chain further reduces the bandgap. as a result, poly[3-hexylthiophene-2,5-diyl-alt-3,4-difluorothiophene] (phtdft) shows homo and bandgap of -5.31/1.83 ev and poly[3,4-dihexyloxythiophene-2,5-diyl-alt-3,4-difluorothiophene] (pdhotdft) shows homo and bandgap of -5.14/1.68 ev, both are lower than -4.76/2.02 ev of p3ht. benefiting from the lower homo, phtdft:pc61bm (1:1) polymer solar cells obtain a power conversion efficiency of 1.11% and an impressed open-circuit voltage of 0.79 v under solar illumination am1.5 (100 mw/cm(2)).
