    摘要: The present invention relates to a concentrator for focusing solar radiation, having surface structuring in the form of one or more Fresnel lenses on the lower side, and to the production thereof from polymeric materials by means of a specific extrusion process. The inventive concentrator can be employed in plants utilizable for photovoltaic or solar heating purposes, and has the required durability and performance in demanding climatic zones. The inventive concentrator enables particularly economic production and efficient concentration of solar radiation onto objects such as solar cells or absorber units, irrespective of the geometry thereof. The inventive concentrator has high longevity and—combined with this—high optical performance when employed in extreme and demanding climatic zones. This relates, for example, to the area of a high-performance solar cell used in concentrating photovoltaics, and likewise to an absorber tube which finds use in concentrating solar thermal collector, for example in the context of parabolic trough technology.

    摘要: The invention relates to surface enhancements for composite mouldings made from polymeric materials and to the use thereof in solar systems. These solar systems may be solar reflectors for concentrating solar radiation, flexible photovoltaic composite films, or CPV (Concentrated Photovoltaics) lenses for concentrating solar radiation.The surface enhancement comprises a self-healing coating based on crosslinkable fluoropolymers, e.g. PFEVE (polyfluoroethylene alkylvinyl ethers). These coatings exhibit good optical properties, can be used in outdoor applications, more particularly in solar applications, over very long periods of time, exhibit self-cleaning properties, and in particular are self-healing in relation to mechanical damage—such as scratching.

    摘要: The present invention relates to laminated solar concentration devices and to the production thereof from polymeric materials. The inventive solar concentration devices can be employed in photovoltaic systems or in solar thermal energy systems. The inventive solar concentration devices comprise Fresnel lenses and enable the efficient concentration of solar radiation onto objects such as solar cells or absorber units, irrespective of the geometry thereof. This relates, for example, to the area of a high-performance solar cell as used in concentrated photovoltaics (CPV), and equally to absorbers which are used in concentrated solar thermal energy systems (CSP). The invention in particular relates to the use of an UV- and weathering-stabilizer package for said laminated solar concentration devices, for improving optical lifetime and weathering resistance, and for preventing delamination. The invention further relates to a surface finish relevant to scratch resistance, antisoil properties, anti-reflection properties and chemicals resistance of the solar concentration device.

    摘要: Alpha-hydroxycarboxylic esters are prepared by a continuous process in which alpha-hydroxycarboxamide is reacted with an alcohol in the presence of a catalyst to obtain a product mixture which contains alpha-hydroxycarboxylic ester, ammonia, unconverted alpha-hydroxycarboxamide and alcohol, and catalyst; wherein reactant streams containing an alpha-hydroxycarboxamide, an alcohol and a catalyst are fed into a pressure reactor. The reactant streams are reacted with one another in the pressure reactor at a pressure in the range of 1 bar to 100 bar; and the product mixture is depleted in alcohol and ammonia by distilling off ammonia at a pressure which is constantly kept greater than 1 bar without the aid of additional stripping media. The continuous process can be employed particularly advantageously on the industrial scale.

    摘要: The invention relates to the use of non-transparent, methacrylate-containing one-, two- or multi-layered films in flexible photovoltaic systems, and to the production of said films by extrusion coating, extrusion lamination (adhesive lamination, melt lamination or hotmelt lamination) or glue lamination. For this purpose, e.g. a thin, inorganic or metallically coated film, for example made of PET, is laminated or coextruded with a weather-resistant film, e.g. a film made of PMMA or PMMA polyolefin coextrudate. In particular, laminates are produced in which at least one of the two layers is non-transparent. An optional inorganic oxide or metal layer has the property of a high barrier effect against water vapour and oxygen while the PMMA layer exhibits weather resistance stability.
