CONDENSING SHEET TYPE SOLAR CELL

PROBLEM TO BE SOLVED: To solve the matters of conventional condensing type solar cell that condensing efficiency is limited, follow-up of sunbeam is difficult and installation space is limited, and to develop an inexpensive condensing sheet type solar cell with good productivity. SOLUTION: The solar cell is constituted by arranging a rodlike or spherical photoelectric conversion element 13 in a composite sheet (condensing sheet) 10 consisting of a transparent layer 11 and a reflective layer 12. The transparent layer 11, the solar cell element 13 and the scattering reflective layer 12 are arranged in this order from the light receiving surface against which sunbeam impinges. The light advanced into the transparent layer 11 reaches the photoelectric conversion element 13 directly or after reflection on the reflective layer 12 and further reflection occurs on the interface of the atmosphere and the transparent layer, so that even the light confined in the transparent layer 11 reaches the photoelectric conversion element 13 easily.
