<p><P>PROBLEM TO BE SOLVED: To provide a photovoltaic implement with versatility in which optical energy such as solar battery can be used as the power source of an electric or electronic unit that is usually used and which can be used instead of a standardized battery. <P>SOLUTION: The photovoltaic implement has a winding core and a photoelectric conversion element which is wound to the winding core, is arranged so that it can freely be pulled out, and is flexible. The multiple photoelectric conversion elements, which are arranged in parallel to the longitudinal direction of a photoelectric conversion sheet and are electrically connected in series, are formed on the photoelectric conversion sheet. The photovoltaic implement has an almost cylindrical shape in a state where the photoelectric conversion elements are wound to the winding core, and it can be attached/detached to/ from the storage of the battery in a prescribed standardized shape. <P>COPYRIGHT: (C)2003,JPO</p> |
