Improving the Efficiency/Cost Ratio by Increasing the Tolerance of your Fresnel System Available to Purchase

In order to achieve competitive system costs in mass‐production, it is essential that CPV concentrators incorporate sufficient manufacturing tolerances. This paper presents an advanced concentrator optic comprising a Fresnel lens and a refractive secondary element that produce simultaneously the light concentration with high tolerance (high acceptance angle) and an excellent light homogenization by Köhler integration. This concentrator compares well with conventional Fresnel‐based CPV concentrators.
