METAL-METAL OXIDE COMPOSITE ELECTRODE, MANUFACTURING METHOD THEREFOR, AND PHOTOELECTRIC CONVERSION DEVICE

摘要

PPROBLEM TO BE SOLVED: To provide a metal-metal oxide composite electrode having an excellent industrial productivity and a uniform and sufficient surface roughness, and to provide a dye-sensitized photoelectric conversion device having a large photoelectric current by adsorbing the sensitization dye on the metal-metal oxide composite oxide electrode. PSOLUTION: A metal selected from among titanium, tantalum, niobium, tungsten and zirconium, or an alloy consisting of mainly the metals, is electrolytically oxidized in an electrolyte solution containing ions including halogen atoms, and thereby the metal-metal oxide composite electrode having the uniform and sufficient roughness can be manufactured and the dye-sensitized photoelectric conversion device having the large photoelectric current is obtained using the composite electrode.
