<P>PROBLEM TO BE SOLVED: To provide a wet solar cell in which an open circuit voltage is not reduced even if the open circuit voltage is high and used for a long period of time. <P>SOLUTION: In the wet solar cell having a structure in which a charge transfer layer is installed between a negative electrode consisting of a photoelectric conversion element wherein a photosensitive layer including a semiconductor layer to which a pigment is adhered is retained on an electroconductive support and opposing electrode, as the charge transfer layer, an ionic conductive composition containing an amide compound having a group shown by a formula in Fig. in a molecule such as 3,4-dihydropyrrole 2-on, and an electrolyte such as 1,2-dimethylpropyl imidazolium iodide, 1-hexyl-3-methyl imidazolium iodide, 1-propyl-3-methyl imidazolium iodide, lithium iodide, and potassium iodide is used. However, hydrogen atom is not bound to nitrogen atom in the formula. <P>COPYRIGHT: (C)2004,JPO |
