<P>PROBLEM TO BE SOLVED: To improve a photoelectric conversion efficiency by increasing an area of a photoelectric conversion region effective for an incident light and decreasing a non-photoelectric conversion region. <P>SOLUTION: A photoelectric conversion device 1 has: a transparent conductive layer 3, a porous oxide semiconductor layer 4 with a colorant, a porous spacer layer 6, and a counter electrode layer 8. All are laminated in this order and formed on one principal surface of a translucent substrate 2. An electrolyte is contained in the porous oxide semiconductor layer 4 and the porous spacer layer 6; a collector 13 is formed on an opposite surface of the counter electrode layer 8 to the porous spacer layer 6; a plurality of through-holes 10 are formed at regular intervals through the counter electrode layer 8, the porous spacer layer 6, and the porous oxide semiconductor layer 4, to reach the transparent conductive layer 3; and a conductor 12 is formed at the center axis part of the through-hole 10, and connected between the transparent conductive layer 3 and the collector 13. <P>COPYRIGHT: (C)2008,JPO&INPIT |
