In this research, vertically oriented TiO_2 nanotube was fabricated on ITO glass by electrochemistry method, and investigated by the measurements of X-ray diffractometer (XRD), scanning electron microscopy (SEM), and ultraviolet-visible (UV/VIS) spectrometer. X-ray diffraction patterns show that the best sintering temperature of TiO_2 nanotube is 500℃, at which TiO_2 anatase phase forms best. SEM images reveal that the diameter and height of TiO_2 nanotube are 70 nm and 230 nm, respectively. Transmittance curves reveal that the transmittance of annealed TiO_2 nanotube is about 80%～90%, and is obviously higher than non-annealed TiO_2 nanotube. The absorption band of annealed TiO_2 nanotube is at 330～370 nm. The results of current-voltage (Ⅰ-Ⅴ) characteristics analysis reveal that dye-sensitized solar cell with TiO_2 nanotube electrode has better Ⅰ-Ⅴ characteristics and efficiency than TiO_2 film electrode. This result may be due to the annealed TiO_2 nanotube applied on the electrode of dye-sensitized solar cell can increase the contact area between TiO_2 and dye, resulting in the enhancement of Ⅰ-Ⅴ characteristics and efficiency for dye-sensitized solar cell.
