Abstract

It is essential to obtain high values of tolerance for CPV concentrators because manufacturing process always implies some accuracy errors. This paper presents the Fresnel Köhler concentrator (FK), an advanced optical concentrator comprising a Fresnel lens as a primary element and a refractive secondary element, both presenting free-form surfaces. This optic produces both, the desired light concentration and high tolerance (i.e. high acceptance angle), as well as an excellent light homogenization by Köhler integration simultaneously. A comparison between the FK and other current conventional Fresnel-based CPV concentrators is also presented, being our concentrator superior to its competitors in terms of tolerances, irradiance homogeneity and manufacturability.
