| Abstract: | A preparation method of a TiO2 highly-ordered porous structure and its application in dye-sensitized solar cells were explored.Polystyrene colloidal crystals were prepared by vertical deposition in a polystyrene suspension.Using the crystals as the template,thin TiO2 films with a highly-ordered nano porous inverse-opal structure were prepared.The micro structures of the colloidal crystal template and TiO2 inverse-opal ordered films were characterized and discussed.Then dye-sensitized solar cells were fabricated with the TiO2 inverse-opal ordered films.The solar cells were characterized by current-voltage(I-V) testing and electrochemical impedance spectroscopy(EIS).Compared with normal nano-particle cells,the open circuit voltage of the inverse-opal device increased by 0.24V,and the internal resistance decreased by 61.9%. |
