DYE-SENSITIZED PHOTOELECTRIC TRANSDUCER AND PROCESS FOR PRODUCING THE SAME, ELECTRONIC APPARATUS AND PROCESS FOR PRODUCING THE SAME, AND ELECTRONIC EQUIPMENT

Document Type and Number:

WIPO Patent Application WO/2006/095520

Kind Code:

A1

Abstract:

A dye-sensitized photoelectric transducer comprising semiconductor electrode (2) with a sensitizing dye adsorbed thereon and counter electrode (3) and, interposed therebetween, electrolyte layer (4), wherein as the molecule of the sensitizing dye, use is made of one having multiple acid functional groups for adsorption on the semiconductor electrode (2). There is provided a dye-sensitized photoelectric transducer wherein high photoelectric transduction efficiency can be realized even when dyes having, as adsorptive groups, carboxylic acid or other acid functional groups which are likely to form association compounds through partial neutralization of the acid functional groups with an alkali compound consisting of a hydroxide of at least one metal or compound selected from the group consisting of Li, Na, K, tetramethylammonium, tetraethylammonium, tetrapropylammonium, tetrabutylammonium, imidazolium compound and pyridinium compound are employed as the sensitizing dye. Further, there is provided a process for producing the dye-sensitized photoelectric transducer.
