<P>PROBLEM TO BE SOLVED: To provide a photoelectric cell capable of maintaining high photoelectric conversion efficiency over a long period of time, by suppressing influence of a water molecule on photoelectric conversion efficiency. <P>SOLUTION: In this photoelectric cell, a substrate (1) having an electrode layer (1) on its surface, and a porous metal oxide semiconductor film (1) adsorbing a photosensitizer formed on the surface of the electrode layer (1), and a substrate (2) having an electrode layer (2) on its surface are disposed so that the electrode layer (1) faces the electrode layer (2), and an electrolyte layer is provided between the porous metal oxide semiconductor film (1) and the electrode layer (2). A water molecule adsorbing agent is contained in the electrolyte layer. The water molecule adsorbing agent is zeolite. The zeolite is one or more selected from ZSM-5 type zeolite, mordenite type zeolite, faujasite type zeolite, A type zeolite, L type zeolite, and β zeolite. <P>COPYRIGHT: (C)2010,JPO&INPIT |
