Abstract

PROBLEM TO BE SOLVED: To adjust incident angle of sun light without special equipment such as frame, etc., by forming a solar cell module consisting of light collecting structure in which a plurality of triangular projections in section are arranged in parallel and uniformly on one side of plate light transmissive body. SOLUTION: Projections having a triangle in section are arranged in parallel and uniformly at least on one side of a plate light transmissive body, forming a light collecting structure 1 of solar battery. The wavy surface of the structure 1 is formed as an integrated shape by arranging triangular prisms on the one side of the plate light transmissive body. The structure 1 is used as constituent element to consistute a solar battery module 3. A sun light entering the module 3 is refracted by the prism effect of the structure 1 and a light reception surface 2 is tilted according to altitude of the sun, so that the sun light can be made to enter a solar battery 4 almost vertically.

The corrugated surface of the light-collecting structure (1) has a shape as if triangular prisms were arranged in parallel on one side of a light transmitting body that was a flat plate, and were integrally formed. Further, in the cross-sectional shape, it is preferable that one side of the light transmitting body has an uneven shape such that long sides and short sides are alternately repeated (FIGS. 1 and 2). The surface and the narrow inclined surface are alternately formed. The wide inclined surface functions as a sunlight receiving surface (2).
