In this paper, the TiO{sub 2} nanospheres and spiny nanospheres were synthesized as the photoanode films of dye-sensitized solar cells (DSSCs) with quasi-solid electrolyte for the improvement of solar conversion efficiency. For a given film thickness, the spherical photoanode films have shorter electron transport time and several times slower recombination than those of nanoparticles, indicating that the charge-collection efficiencies of the spherical photoanodes were markedly improved. DSSCs containing the TiO{sub 2} spherical photoelectrode exhibited higher short circuit current because of this specific morphology.
