We report herein the promising application of TiO2 nanotubes formed on a Ti substrate to a flexible dye-sensitized solar cell illuminated from the back-side. We found that anodization of a Ti substrate in an extremely dilute perchloric acid solution yielded the formation of a high aspect-ratio TiO2 nanotube layer on the Ti substrate. The nanotube layer has the equivalent surface area for dye-adsorption to a TiO2 nanoparticle layer. This novel one-dimensional TiO2 material provided efficient carrier generation interfaces as well as an efficient transport pathway for the carriers, evidenced by the enhanced photocurrent and photovoltage of the cell.
