Concentrator for solar radiation and use thereof

摘要

The invention relates to a concentrator arrangement for solar radiation which has a beam splitter for deflecting solar radiation by means of total reflection. Furthermore, the invention relates to a device for concentrating and converting solar energy which has such a concentrator and at least one device for the conversion of solar energy. Such devices for the conversion of solar energy are for example solar cells, solar modules or thermal solar collectors. The concentrators according to the invention are used for concentrating solar radiation just as in sun protection panels.

主权项

1. A device for concentrating and converting solar energy, comprising at least one concentrator comprising at least one beam splitter for deflecting solar radiation, the beam splitter is configured to have a side oriented towards a source of solar radiation and a side oriented away from the source of solar radiation, the beam splitter having, on the side orientated away from the solar radiation, a structuring which deflects solar radiation impinging on the beam splitter in two different directions by means of total reflection, and at least two devices for the conversion of solar energy which are arranged in an offset manner, the at least one concentrator being positioned between the two devices for the conversion of solar energy and in the direction of incident solar radiation in front of two devices for the conversion of solar energy, such that one part of incident solar radiation directly impinges on the two devices for the conversion of solar energy without impinging on the beam splitter, and such that the solar radiation deflected by the beam splitter is directed onto the two devices for the conversion of solar energy between which the concentrator is localized, wherein the beam splitter is configured as a planar disc or plate and the structuring is configured in the form of essentially isosceles prisms.
