Abstract: Provided is a fine conductive particle that can be produced by a simple method, can impart excellent conductivity (in particular, conductivity in the thickness direction) to a cured article when incorporated in a small amount into the cured article, and allows the cured article to exhibit excellent transparency and conductivity. The conductive fiber-coated particle includes a particulate substance and a fibrous conductive substance. The particulate substance is coated with the fibrous conductive substance. In the conductive fiber-coated particle, the fibrous conductive substance preferably includes a conductive nanowire. More preferably, the conductive nanowire preferably includes at least one selected from the group consisting of metal nanowires, semiconductor nanowires, carbon fibers, carbon nanotubes, and conductive polymer nanowires.

Abstract: A composition that can form a photoelectric conversion layer having an excellent adhesion to a substrate is provided without a sintering step. The composition comprises at least a semiconductor (e.g., a titanium oxide particle) and an ionic polymer (e.g., a fluorine-series resin having a sulfo group), and the ratio of the ionic polymer relative to 1 part by weight of the semiconductor is 0.1 to 30 parts by weight. The composition may further contain a dye (a sensitizing dye). The photoelectrically convertible layer can be formed by coating a conductive substrate with the composition without sintering the semiconductor.

Abstract: A composition that can form a photoelectric conversion layer having an electricity storage function is provided. The composition comprises at least a semiconductor (e.g., a titanium oxide particle) and an ionic polymer (e.g., a fluorine-series resin having a sulfo group), and the ratio of the ionic polymer relative to 1 part by weight of the semiconductor is not less than 0.05 parts by weight. The composition may further contain a dye (a sensitizing dye). An electrode provided with a photoelectric conversion layer formed from the composition can be used in combination with, in particular, an electrode having a porous layer to give a photoelectric conversion element having an excellent electricity storage function.
