<P>PROBLEM TO BE SOLVED: To provide a dye-sensitized photoelectric converter inexpensive and excellent in photoelectric conversion performance. <P>SOLUTION: The dye-sensitized photoelectric converter 10 is comprised of mainly a transparent substrate 1 such as glass; a semiconductor layer 3 held with photo-sensitized dye; a current conductive layer (a negative electrode) 12; an electrolyte layer 4; a counter electrode (a positive electrode) 5; a counter substrate 6; and a sealing material (not shown in a figure). A porous layer obtained by sintering fine particles of titanium oxide TiO<SB>2</SB>is used as the semiconductor layer 3, an organic electrolyte containing an oxidation reduction species such as I<SP>-</SP>/I<SB>3</SB><SP>-</SP>is used as the electrolyte layer 4, and the counter electrode 5 laminated with a platinum layer or the like is installed on the counter substrate 6. A current collector layer 12 is arranged so as to come in contact with the semiconductor layer 3 on the side far from a light incident side. Therefore, shading of incident light to the semiconductor layer 3 by the current collecting layer 12 is prevented. An opening part (a cut-out part) 13 for making an electrolyte of the electrolyte layer 4 permeate to the semiconductor layer 3 is installed in the current collector layer 12. <P>COPYRIGHT: (C)2007,JPO&INPIT |
