Abstract

Abstract: The transparent titanium dioxide TiO₂ film of high surface area has been prepared.Atomic force microscope analysis confirms that the film is composed of interconnected particles and pores. Sensitization of TiO₂ microporous electrode with porphyrin molecules extendsthe absorbance of the electrode into visible region. The photoelectric conversion study showsthat the dye-sensitized TiO₂ microporous electrode is attractive in photoelectrochemical conversion of solar energy in the future.

Key words: titanium dioxide, porphyrin, photoelectric conversion
