NOVELTY - The fluorescent collector comprises fluorescent dye, a sort of semiconductive nanoparticles, a substrate, a polymer or sol-gel-layer as carrier structure for the semiconductive nanoparticle. The surface of the fluorescent collector is completely simulated up to an area determined for coupling of solar light and fluorescence radiations or has diffuse reflectors in order to enable an internal reflexion of solar radiation (3) entering into the collector. A photovoltaic cell (1, 1', 1'') is arranged for the transformation of the coupled radiation into electric energy.    USE - Fluorescent collector useful for concentrating and transformation of solar radiation into electric energy, in combination with solar thermal plant (claimed).    ADVANTAGE - The fluorescent collector is simple and ensures economical and efficient concentrating and transformation of solar radiation into electric energy without requiring expensive tracking system.    DETAILED DESCRIPTION - The fluorescent collector comprises fluorescent dye, a sort of semiconductive nanoparticles, a substrate, a polymer or sol-gel-layer as carrier structure for the semiconductive nanoparticle. The surface of the fluorescent collector is completely simulated up to an area determined for coupling of solar light and fluorescence radiations or has diffuse reflectors in order to enable an internal reflexion of solar radiation (3) entering into the collector. A photovoltaic cell (1, 1', 1'') is arranged for the transformation of the coupled radiation into electric energy. The nanoparticles and the fluorescent dye are arranged in the carrier structures separated from one another. The polymer layer is formed from transparent polymer. The substrate and/or the polymer layer consist of additives such as antioxidants and radical catcher. The fluorescent dye consists of 99% of fluorescence quantum yield. The semiconducting nanoparticles have quantum size effect. Ligands adsorb or are covalently or ionically bonded on the surface of the nanoparticles. The collector consists of a fluid-solid-collector, and a collector batch having hybrid collectors and/or polymer layers, where different fluorescent dye and/or semiconducting nanoparticles are contained in the polymer layer. The substrate consists of encapsulated glass box in which semiconducting nanoparticles dispersed in a solvent are contained. The substrate is combined with a polymer layer having fluorescent dye. The thickness of the polymer layer is 10 nm-10 mm. The substrate and the polymer layer have a same refraction index. A photovoltaic cell is connected to an edge of the collector by a high refractive index contact medium. The collector comprises a band-stop filter on the surface turned to the solar radiation in the form of a photonic crystal layer. The polymer layer is produced by UV-polymerization or polymer solution.
