Abstract

A novel composite photoanode for dye-sensitized solar cells (DSSCs) was fabricated by electrospinning the TiO₂ nanofibers onto the TiO₂ nanoparticles as a light scattering layer. The magnesium oxide (MgO) was doped in the TiO₂ nanoparticles in order to suppress the recombination of electron and hole. When the composite photoanodes were sensitized by using the organic triphenylamine dyes (SD2, SD3) or a ruthenium dye (N719) with the co-adsorbent chenodeoxycholic acid (CDCA), the high power conversion efficiency (η) of 6.35%～8.85% was obtained under simulated AM 1.5 irradiation (100 mW/cm²). Meanwhile, the power conversion efficiency of the quasi-solid DSSCs reached about 90% that of liquid electrolyte DSSCs.

Key words: electrospun, microporous membrane, dye-sensitized solar cells, power conversion efficiency
