PURPOSE: To increase the output current from a solar cell significantly through the use of a reflector, e.g. a mirror.

CONSTITUTION: A solar cell body 1 is fixed with a reflector 2 for reflecting the solar 3 beam. In other words, the solar cell 1 is fed with a solar beam 4 reflected on a reflector 2, e.g. a mirror, or fed with the solar beam 4 in parallel with the direct solar beam using an optical fiber. This constitution increases the output current of the solar cell 1 significantly. When the number of reflectors is increased, the output current can be increased correspondingly. This constitution increases the output current significantly as compared with a conventional solar cell.
