CONCENTRATOR FOR POLYCHROMATIC LIGHT |
摘要 |
One example of a solar voltaic concentrator has a primary Fresnel lens with multiple panels, each of which forms a Kohler integrator with a respective panel of a lenticular secondary lens. The resulting plurality of integrators all concentrate sunlight onto a common multi-junction photovoltaic cell. The integrators provide matching illumination in the different wavebands required by the different junctions. Luminaires using a similar geometry are also possible. |

1. An optical device comprising:
a multi junction photovoltaic cell, wherein each junction is operative to convert light of a respective waveband into electricity; a refractive first optical element having a plurality of segments each arranged to focus incoming collimated light from a common source; and a second optical element having a plurality of segments, each arranged to direct light from a respective segment of the first optical element onto the photovoltaic cell; wherein the acceptance angles for incoming light of two of the said wavebands are within a ratio of 5:4 to 4:5. |
