PHOTOELECTRIC-CONVERSION EFFICIENCY IMPROVING SYSTEM FOR SOLAR CELL MODULE

PROBLEM TO BE SOLVED: To provide a photoelectric-conversion efficiency improving system for a solar cell module, capable of being provided at low cost using a simple constitution, while further improving the efficiency of a photoelectric conversion. SOLUTION: In the solar cell module generates power, by arranging a plurality of silicon solar cells 1 in two dimensions, a light irradiating the outside at the ends of the solar cells is refracted by condensing means 2, disposed to upper parts at the positions of the ends of the adjacently disposed solar cells 1; and the condensing means are not arranged at positions opposed to the solar cells 1 on the light-receiving surfaces of the solar cells. In the solar cell module, the irradiating light is projected directly on the light-receiving surfaces of the solar cells. COPYRIGHT: (C)2011,JPO&INPIT
