<P>PROBLEM TO BE SOLVED: To provide a photoelectric converter with an excellent form adapted to an incident light confinement effect, capable of obtaining larger output energy per primary sunlight incident unit area, in order to solve a problem that a conventional convexoconcave solar battery cannot use most light energy. <P>SOLUTION: For realizing super high performance photoelectric conversion, an outside wall including a constriction forming unit 9 that uses a silicon material and a scoop unit 10 formed on a lower side of a constriction portion, is provided so as to face in a primary sunlight incident direction. A photoelectric conversion region is formed in a constriction form. An effective photoelectric conversion surface area per a primary sunlight incident unit area is set at larger size, and an optical path is set at larger size. The incident light is photoelectrically converted so as to reduce a light amount to be reflected to the primary sunlight incident direction. <P>COPYRIGHT: (C)2012,JPO&INPIT |
