TECHNOLOGY FOCUS - POLYMERS - Preferred Device: The UV protected laminated solar concentration device comprises an additional polymer surface protecting layer which is bond to the light source facing surface of UV protecting layer, either directly or via an adhesive layer, or to the light source facing surface of carrier layer, either directly or via an adhesive, and which has soil-repellent and/or scratch resistance and/or abrasion resistance-improving and/or anti-reflection properties. Preferred Process: In manufacturing UV protected laminated solar concentration devices, the laminate between carrier layer and polymeric film is formed without adhesive layer and that the process comprises providing a film having a first surface embossed with optical structures and an opposite second surface; guiding the film to a nip point of a pair of lamination rolls; feeding a carrier layer or an UV protected carrier layer or a laminate of carrier layer and UV protection layer or a coextrudate of carrier layer and UV protection layer to the nip point, the carrier layer having a surface temperature of the surface intended to be bond to film effective to enable thermal bonding between the carrier layer and the polymeric film; and laminating the carrier layer to the second surface of the polymeric film. The polymeric film comprises an imposed square or rectangular Fresnel lens pattern; or polymeric film comprises a matrix of square individual Fresnel lenses arranged in a grid pattern that the film is configured as a linear Fresnel lens where the pattern is continuous for the length of the film. Adhesive layer is a solvent cement, preferably a formulation high in chlorinated solvents. The polymeric film is composed of polymers selected from poly (meth) acrylate, polycarbonate, cyclic olefin polymers, polystyrene, polyvinylidenedifluoride, polyurethanes or mixtures or copolymers, and/or carrier layer is a polycarbonate, polystyrene, styrene copolymer, polyester, preferably polyethyleneterephtalate or Polyethylene Terephtalate Glycol (PETG), fluoropolymers and/or para-methoxy-N-methylamphetamine (PMMA) based film or sheet and/or a two-layer PMMA/polyvinylidene difluoride (PVDF) film or sheet and/or a film or sheet made of a PMMA/PVDF blend, and/or UV protecting layer consist of a transparent single- or multilayer (multi-sublayer) plastics foil, encompassing polymethyl (meth) acrylate or polymethyl (meth) acrylate and polyvinylidene fluoride, in each case in at least one sublayer, or polymethyl (meth) acrylate and polyvinylidene fluoride in a mixture in at least one sublayer. The carrier layer and/or the UV protecting layer comprise a mixture of UV absorbers, composed of at least one triazine and of at least one benzotriazole, and comprises at least one UV stabilizer which is a hindered piperidine (HALS) compound or a mixture of various HALS compounds. The mixture of UV stabilizers and UV absorbers is composed of the following amounts, each amount based on the weight of the monomers used to prepare the respective layer: from 0.1% by weight to 10% by weight, preferably from 0.5% by weight to 4% by weight, of the benzotriazole-type UV absorbers, from 0.1% by weight to 5% by weight, preferably from 0.5% by weight to 3% by weight, of the triazine-type UV absorbers, and from 0.1% by weight to 5% by weight, preferably from 0.2% by weight to 2% by weight, of the HALS-type UV stabilizers. The UV protecting layer is composed of poly (meth) acrylate and polyvinylidene fluoride in a ratio by weight of from 1:0.01 to 0.3:1, preferably from 1:0.1 to 0.4:1, and comprises UV stabilizers and UV absorbers or that the UV protecting layer encompasses two sublayers, of which one is a sublayer composed of poly (meth) acrylate and the other is a sublayer composed of polyvinylidene fluoride. Polymeric film has a thickness in the range of from 0.01 to 10 mm, preferably 0.025 to 2 mm, more preferably 0.025 to 1 mm, particular preferred from 0.05 to 0.75 mm, very particular preferred of from 0.1 to 0.5 mm or 5 to 0.9 mm, and/or the carrier sheet has a thickness in the range of from in the range from 0.1 mm to 50 mm, preferably in the range from 0.5 to 25 mm, more preferably in the range from 1 to 20 mm, particular preferred in the range of from 2 to 20 mm and very particular preferred of from 2 to mm and 2 to 7 mm, and/or the polymeric UV protecting layer film has thickness in the range from 10 to 250 mu m, more preferably in the range from 40 to 120 mu m and particular preferred of from 50 to 90 mu m. The carrier layer comprises at least one heat stabilizer.
