MODIFIED TITANIUM OXIDE MICROPARTICLE AND PHOTOELECTRIC TRANSDUCER MAKING USE OF THE SAME

摘要

[PROBLEMS] To develop metal microparticles useful in dye-sensitized solar cell, etc. and to provide a photoelectric transducer capable of exhibiting enhanced release voltage in dye-sensitized solar cell. [MEANS FOR SOLVING PROBLEMS] There are provided modified titanium oxide microparticles comprised of titanium oxide and one or two or more types of nontitanic metal oxides (including silicon oxides) selected from the group consisting of periodic-table group IB oxides, group IIA oxides, group IIB oxides, group IIIA oxides, group IIIB oxides, group IVA oxides other than titanium oxides, group IVB oxides, group VIA oxides, group VIII oxides and vanadium oxides. Further, there is provided a photoelectric transducer making use of the modified titanium oxide microparticles.
