<P>PROBLEM TO BE SOLVED: To provide an entirely novel secondary cell capable of optical charging and an electrochemical capacitor which can repeat charging and discharging with light through integration of an electrode performance for optical power generation and that for charging into one electrode material. <P>SOLUTION: Of a photoelectric cell laminating and integrating a photoelectrode layer and a counter electrode layer at each side of an ionic electrolyte layer as an intermediate layer, the photoelectrode layer is structured by a combination of a photosensitive semiconductor capable of absorbing visible light with a wavelength of 400 nm or more and a solid electrode active material making an oxidation-reduction reaction in electrically coupling with the semiconductor. Hence, the secondary cell capable of the optical charging in which charging progresses based on the oxidation-reduction reaction by light absorption of the semiconductor. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
