<p><P>PROBLEM TO BE SOLVED: To provide a light charge type secondary battery which has charging performance of high charging efficiency and small deterioration by combining a flexible photoelectric conversion sheet where a photoelectric converting element is formed and a storage battery with each other. <P>SOLUTION: The light charge type secondary battery is equipped with a core part, the photoelectric conversion sheet with the photoelectric converting element, the storage battery, and a control circuit part and formed in a nearly cylindrical shape on the whole with the core part wound with the photoelectric conversion sheet, the core part being provided integrally with an upper flange and a lower flange positioned at both end parts and formed in a nearly circular flat plate shape and being wound with the photoelectric conversion sheet. The light charge type secondary battery has a sheet part extending from an internal end part of an effective part of the photoelectric converting element of the photoelectric conversion sheet to an internal end part of the photoelectric conversion sheet and a sheet part extending from an external end part of the effective part of the photoelectric converting element of the photoelectric conversion sheet to an external end part of the photoelectric conversion sheet, both the sheet parts having substantially the same bending elasticity with the effective part of the photoelectric converting element. <P>COPYRIGHT: (C)2003,JPO</p> |
