| Popis: | Fresnel lens is widely used in concentrating photovoltaic (CPV) systems as a primary optical element. It focuses sunlight on small solar cells or on the entrance apertures of secondary optical elements. In this work, we present a performance analysis of a non-imaging Fresnel lens as a primary optical element for different values of focal length. Results show, among others, the necessary use a secondary stage of concentration in order to achieve good performances in terms of the uniformity of the flux and a large acceptance angle compared with those of a Fresnel lens used alone. |
