Abstract
The invention relates to a method and a device for a concentrator/solar collector for splitting solar radiation into various spectral colours by means of colour-selective mirrors, and for concentrating the same onto a plurality of semiconductor-photovoltaic cells optimised for various light colours. The inventive device is used to convert the energy of the solar radiation into an electrical current and heat with a high efficiency.

Process for the conversion of solar radiation into electric power and heat with one or several colour-selective interference filter reflectors that will split up solar radiation into different wavelength ranges and concentrate it on several photovoltaic cells that are made of semi-conductors and that have been optimised for different light colours, wherein the light will be separated into at least two spectral wavelength ranges with the help of movable interference reflector films (2), with every film reflecting one wavelength range and transmitting another part.
Appliance of a concentrator solar collector with colour-selective reflectors, wherein lenses, preferably Fresnel lenses (1), are installed in a given frame (6) of the solar collector and directed towards the sun light, with a photocell being in the focal point of the lens, and that a movable interference reflector film (2) has been installed between the lens and the photocell.
