Abstract
Optics with high optical efficiency and reliability are the key components for CPV modules as well as high efficiency solar cells and a high accuracy tracker. The present paper describes the optical design, simulation and materials, including a direct comparison of geometrically identical lens designs for different materials i. e. PMMA (or acrilic) and silicone-on-glass (SOG) respectively, and glass secondary in three different geometries. The Fresnel lenses manufactured as 5×4 monolithic parquets are called Triple Primaries, and serve as test samples and off-the-shelf products of Concentrator Optics GmbH.
