DYE-SENSITIZED SOLAR CELL

摘要

A method for making a dye-sensitized solar cell having a semiconductor film that exhibits high power generating efficiency and that can be formed at relatively low temperature is provided. Titanium oxide paste is applied and dried on a transparent conductive film 2 to form a titanium oxide layer. An aqueous peroxotitanic acid solution 11 is dropwise-placed and heated on the titanium oxide layer. During this process, the aqueous peroxotitanic acid solution penetrates sites on which titanium oxide particles 10 are not adsorbed on the transparent conductive film 2, and the aqueous peroxotitanic acid solution 11 reacts to generate titanium oxide 11A. The titanium oxide 11A is generated at gaps s,t between the titanium oxide particles 10 to form tight linkages between titanium oxide particles 10, resulting in high power generating efficiency.
