Nanoporous Titanium Dioxide

Fabrication of nanoporous titanium dioxide (TiO2) films was examined for their application as the negative electrode of a dye-sensitized solar cell (DSC). Composite films were fabricated by aerosol deposition using a powder mixture of TiO2and aluminum nitride (AlN). A nanoporous structure was subsequently formed in the film by dissolving the AIN in hot water. Remarkable differences in the surface morphology of the films were observed for different mixing ratios of TiO2and AlN particles. AlN particles remained in the films, but not at the surface. The power conversion efficiency of a DSC was improved by incorporating these nanoporous TiO2films.
