| 中文摘要 | the electron donor of a d-pi-a dye is known for its capability to tune both the electronic trait and packing mode of dye molecules chemisorbed on titania nanocrystals of dye-sensitized solar cells (dscs), bringing on the opportunity to impact cell performance by modulating the physicochemical characteristics at the titania/dye/electrolyte interface. in this paper, we scrutinize the influences of arylamine electron donors on the optoelectronic features of thin-film dscs employing a tris(1,10-phenanthroline) cobalt(ii/iii) redox electrolyte, by use of four cyclopentadithiophene dyes (c218, c244, c245 and c246) with the respective dihexyloxy-, diphenothiazinyl- or di-tert-butylphenyl-substituted triphenylamine and n-hexyl-carbazole electron donors. amongst these electron donors, dihexyloxy-substituted triphenylamine is found to present the strongest electron-donating capacity, endowing the corresponding c218 dye with evidently red-shifted light absorption in comparison with the other three congeners. transient absorption measurements show that all dscs exhibit expeditious dye regeneration, guaranteeing efficient long-distance charge separation at the titania/dye/redox couple interface. furthermore, it is worthwhile noting that the c218 dye prompts the highest open-circuit photovoltage amongst these chromophores, which is primarily attributed to the positive effect of slow cobalt(iii) interception of titania electrons, highlighting the superiority of applying dihexyloxy-substituted triphenylamine as the electron donor for a cyclopentadithiophene dye. |
