Abstract

PURPOSE:To achieve a simple, small sized and low cost condenser by constituting the frontmost layer being an incident plane of light with a transparent plate with the highest refractive index and overlapping transparent plates with smaller refractive index at the back sequentially for incorporation. CONSTITUTION:A condenser consists of a condensing cell 1 and a light transmission plate 2, a solar cell 3 is fitted at the lower end of the plate 2, and the assembly is supported on a radiator plate 4. The cell 1 is made, e.g. of lead- glass, and the refractive index is smaller at the upper plane and it is gradually greater toward the lower plane. A front plane 9 of the plate 2 has the maximum refractive index, the front plane 10 is minimum and the refractive index is gradually changed between both the planes. Incident lights 7, 8 when the sum is at low and high positions, are refractive in the cell 1 and transmitted in parallel with the cell 1, refractive in the plate 2 downward and collected in the solar cell 3. Thus, a condenser which is simple, small in size and low in the cost can be obtained.
