PURPOSE: To miniaturize and lighten a condensing solar cell device to generate a full generating power. CONSTITUTION: Four solar cells 2 for movement are provided on the periphery of a solar cell 1 for generation. Electromagnets 21, which are respectively connected with these cells 2, are provided under the cells 2 and at the same time, the cell 1, the cells 2 and the electromagnets 21 are installed on a cell support 14. Moreover, a permanent magnet 26 on a ring is arranged on the periphery of the cell 1. When a condensing spot 13 is shifted by a condensing lens 11, light strikes on some one of the cells, whereby a current is made to flow through the electromagnet 21, which corresponds to the cell 2 struck with the light, and the electromagnet 21 and the magnet 26 attract to each other to move the support 14. When the spot 13 is returned on the cell 1, a generation is stopped due to the cells 2 and the movement of the support 14 is stopped. |
