Abstract:
1. A photoelectrode for dye-sensitized solar cells, comprising a porous titanium oxide film formed on an electrically conductive transparent layer formed on a transparent high polymer film, the porous titanium oxide film being obtained by a process comprising the steps of: applying a titanium oxide particle dispersion liquid in methanol and/or ethanol to the surface of the electrically conductive transparent layer by spray coating in such a manner that the atomized droplets of the dispersion liquid discharged from the spray coater have a mean diameter of about 1 μm to about 25 μm; and drying the coating by heating at a temperature of about 130° C. to about 180° C. or by irradiation with electromagnetic waves to form a porous titanium oxide film.
