<P>PROBLEM TO BE SOLVED: To provide a dye-sensitized solar cell having high efficiency improved in electromotive force, maximum output, and cycle characteristics. <P>SOLUTION: The dye-sensitized solar cell has an electrode substrate, a first transparent conductive layer, a metal oxide film adsorbing dyes, an electrolyte layer, a second transparent conductive layer, and a counter substrate formed in this order, and the electrolyte layer contains a nitroxy radical compound. By irradiation of light, interpolar potential is generated, and optical induced current is obtained. The nitroxy radical compound becomes a redox mediator in a system which does not contain redox ion, such as iodine or the like, at all. <P>COPYRIGHT: (C)2009,JPO&INPIT |
