Kurzfassung:
TiO 2 hollow spheres were successfully synthesized using poly styrene as the template. Dyesensitized solar cells are fabricated based on double-layered composite films of TiO 2 nanoparticles and TiO 2 hollow spheres. The photoelectric conversion performances
of Dye-sensitized solar cells based on TiO 2 nanoparticles/TiO 2 nanoparticles, TiO 2 nanoparticles/TiO 2 hollow spheres and TiO 2 hollow spheres/TiO 2 hollow spheres double-layered films are investigated, and their photoelectric
conversion efficiencies were determined to 4.52, 7.10 and 5.48%, respectively. Dye-sensitized solar cells based on double layered composite films of TiO 2 nanoparticles and TiO 2 hollow spheres exhibit the highest photo-electric conversion efficiency mainly due to the combined
effect of two factors, the high light scattering of over-layer hollow spheres that enhance harvesting light of the Dye-sensitized solar cells and the under-layer TiO 2 nanoparticle layer that ensures good electronic contact between TiO 2 film and FTO conducting glass. The
double layered composite TiO 2 film electrodes are a promising development in enhancing the performance of dye-sensitized solar cells.
