In this work, in order to manufacture the photoelectrode of dye-sensitized solar cells, thedifferent anatase TiO2 paste was prepared by simple route using hydrothermal method. In comparisonwith the traditional preparing process, the hydrothermally synthesized TiO2 gel was used to make pastedirectly. Thus, the making process was simplified and the solar conversion efficiency was improved. Incomparison with 5.34% solar energy efficiency of HP-1 photoelectrode, the 6.23% efficiency of HDP-1electrode was improved by 16.67%. This is because hydrothermally synthesized TiO2 gel was used tomake paste directly, the dispersibility between TiO2 particles was improved and get the smoothernetwork, leading to the charge transport ability of the electron generated in dye molecular was improved. Further, HDP-2 photoelectrode delivered the best results with Voc (open circuit voltage), Jsc (shortcircuit current density) FF (fill factor) and η(solar conversion efficiency) were 0.695 V, 15.81 mA cm-2,61.48% and 6.80%, respectively. In comparison with 5.34% of HP-1 photoelectrode, it was improved by27.34%.
