Contribution to solar concentrators design for photovoltaic application

International audienceSome properties of solar concentrator based on a Fresnel lens, a compound parabolic concentrator (CPC) and a cone are investigated. The effect of the source incidence angle on the focal point of the lens is highlighted and a procedure for a cone design is presented. This later defines also the sizes of the primary opti
