After the modification, the electrodes were used as a photo-anode in the dye-sensitized solar cells (DSSCs). Firstly, the electrochemical deposition method was applied to deposit a Zinc Oxide semiconducting material on TiO2 nanotube array. For 60 min-electrodeposition, ZnO had a high density and good homogeneity, and a maximum surface roughness helps to improve the dye adsorption capacity, the photoelectric conversion efficiency was up to 3.755 %. Secondly, the use of hydrothermal method to manufacture a modified TiO2 electrode, samarium oxide (Sm2O3) was doped into the TiO2 nanotube array, and exhibited a down conversion luminescence property. When Sm2O3 increases, TiO2 grain size becomes smaller and TiO2 nanotube array surface covered with of the floc Sm2O3. Because of the Fluorescence property, the TiO2 electrode doped with 0.02 M Sm2O3 demonstrates a higher photoelectric conversion efficiency of 73.1 % than the pure TiO2 electrode.
