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. |
