<p>The invention pertains to electricity generation using sunlight, and in particular to light concentrators for solar panels and solar panels incorporating them. It comprises a concentrator for collecting and guiding sunlight to a transducer that converts it to electricity. The concentrator comprises a pair of adjacent solid elongate transparent elements having a refractive index greater than air. Each of the elements has a transparent upper surface, a mirrored lower surface and an output surface that is smaller than the upper surface and substantially perpendicular to it. The arrangement being such that the two output surfaces of the pair of adjacent elements sandwich an optical/electrical transducer between them to deliver concentrated solar radiation to both sides of the transducer. In a further aspect the invention is a solar panel comprising plural of the concentrators arranged side by side. In this case each element may be arranged to guide solar light to a transducer sandwiched between it and an adjacent element.</p> |
