NEW SOLAR CONCENTRATION DEVICES

WIPO Patent Application WO/2012/100876

A3

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.
