Abstract
Disclosed are a method for effectively preventing the contact between the surface of a titanium oxide semiconductor electrode and an electrolyte solution, a photoelectric conversion device exhibiting high photoelectric conversion efficiency, and a dye-sensitized solar cell using the said photoelectric conversion device. The photoelectric conversion device comprising a dye-sensitized semiconductor electrode is manufactured by letting a semiconductor adsorb a sensitizing dye, then rinsing the dye-adsorbed semiconductor, and finally letting the rinsed dye-adsorbed semiconductor adsorb a carboxylic acid in supercritical carbon dioxide. The adsorption of a dye and the rinsing are performed preferably in supercritical carbon dioxide in the presence or absence of an alcohol of 1-4 carbon atoms.
