Fabrication of Dye-Sensitized Solar Cells with Electrolyzed TiO2 Nanotube Array Films

A TiO2 nanotube array film was synthesized by the anodic oxidation of a Ti plate in an NH4F electrolyte. The film was broken into nanotubes by carrying out ultrasonication. The nanotube powder was mixed with TiO2 nanoparticle powder to form a paste. The paste was used in the fabrication of ceramic porous electrodes of dye-sensitized solar cells.
