PURPOSE:To make it possible to transduce solar energy into electric power at high efficiency, by constituting a generator with a condensing mirror and a generating part, facing a condensing mirror, and in which the heat receiving side of a thermoelectric element is closely attached to the non-light receiving surface of a solar cell through an electric insulating layer, and arranging the generating part in the vicinity of the focal position of the facing the condensing mirror. CONSTITUTION:A condensing mirror 1, which is also used as a heat radiating plate, tracks the sun and condenses sunlight 6. The light is inputted into a generating part 2. Part of the sunlight is transduced into electricity through a solar cell 4 in the generating part 2. The remaining sunlight is transduced into heat. The temperature of the solar cell 4 is increased. The temperature of the light receiving side of a thermoelectric element 5, which is closely attached to the solar cell 4 through an electric insulating layer 9, is increased. Meanwhile, the heat radiating side of the thermoelectric element 5 is closely attached to a condensing mirror 1', which is also used as a heat radiating plate, through an electric insulating layer 10. Therefore, a large temperature difference is yielded between the heat receiving side and the heat radiating side of the thermoelectric element. Electromotive force is generated between a P-type semiconductor 7 and an N-type semiconductor 8' owing to said temperature difference. |
