<P>PROBLEM TO BE SOLVED: To provide a photoelectric conversion element having a new structure capable of increasing light receiving efficiency and power generating efficiency per unit area as well as doing away with a substrate with a transparent conductive metal oxide coated, and being stably manufactured in a simple process at low cost. <P>SOLUTION: The photoelectric conversion element 1 is provided with an independent first electrode 10 and a second electrode 20 arranged with electrolyte 30 in-between. The second electrode is a platy conductive base material with at least a part covered by a nonconductive film 25, and the first electrode is in a linear shape and is composed of a first wire rod 11 having at least conductivity and a porous oxide semiconductor layer 12 arranged on an outer periphery of the first wire rod and carrying a colorant, and moreover is arranged so as to encircle the outer side of the second electrode. The electrolyte is contained in a space of the porous oxide semiconductor layer and/or the nonconductive film, and the porous oxide semiconductor layer provided on the first electrode has a structure in which it is arranged only on a region β excluding a region α of the first electrode opposing to the second electrode. <P>COPYRIGHT: (C)2010,JPO&INPIT |
