摘要：
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 (q) of 6.35%similar to 8.85% was obtained under simulated AM 1.5 irradiation (100 mW/cm(2)). Meanwhile, the power conversion efficiency of the quasi-solid DSSCs reached about 90% that of liquid electrolyte DSSCs.
