<p>PROBLEM TO BE SOLVED: To provide a photovoltaic power generating system which uses a reflecting mirror as a condenser and is capable of increasing the quantity of light impinging on the light receiving plane of a solar cell, preventing the temperature of the light receiving plane of the solar cell effectively from rising, and effectively increasing its electromotive force (quantity of current). SOLUTION: A photovoltaic power generating system 100 is equipped with a solar cell 4 provided with a light receiving plane 41, and reflecting mirrors 10a and 10b which are so arranged as to turn the reflected light from their reflecting surfaces 101a and 101b to the light receiving plane 41 of the solar cell 4. The reflecting mirrors 10a and 10b include dielectric multilayered reflecting layers of polymer, reflect light of a reflection wavelength band, containing light effective for making the solar cell 4 generate an electric power at a prescribed rate, and enable light of a transmission wavelength band longer than the reflection wavelength band to penetrate at a prescribed rate.</p> |
