<p>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 canbe used in combination with, inparticular, an electrode having a porous layer to give a photoelectric conversion element having an excellent electricity storage function.</p> |
