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, both with broken rotational symmetry, an optic producing both the desired light concentration with high tolerance (high acceptance angle) as well as an excellent light homogenization by Köhler integration. This concentrator compares well with conventional Fresnel-based CPV concentrators.
为了在大规模生产中实现具有竞争力的系统成本，CPV聚光器纳入足够的制造公差至关重要。本文介绍了一种先进的聚光器光学器件，它由一个菲涅耳透镜和一个折射二次元件组成，两者均具有破缺的旋转对称性，该光学器件既能以高公差（高接收角）产生所需的光聚光，又能通过柯勒积分实现出色的光均匀化。这种聚光器与传统的基于菲涅耳的CPV聚光器相比具有优势。
