<p><P>PROBLEM TO BE SOLVED: To provide a photovoltaic device in which stability and reproducibility are more improved. <P>SOLUTION: The present invention relates to a type of solid-state photovoltaic cell 1 that includes three organic and solid-state materials, and further includes: porous layers 2 of a transparent n-type semiconductor compound; a layer 3 of a transparent p-type semiconductor compound for filling at least part of a hole of the porous layers; and an inorganic absorber compound for forming an aggregate 4 between the two semiconductor compounds of the n-type and p-type layers at least part of which is discontiguous, wherein the semiconductor compound and the absorber include different oxidation products 5, and the oxidation products form a discontinuous portion of an interface layer which is disposed between the two layers of the n-type and p-type semiconductor compounds and/or between the aggregate of the absorber and a layer of the p-type semiconductor compound. The oxidation product of the interface layer is obtained by oxidation treatment of the cell 1 and includes visible light irradiation under the existence of a gas containing oxygen. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
