Ultra-High Concentrator Photovoltaic (UHCPV) designs with up to more than 6000× geometrical concentration and optical efficiency of 80% are demonstrated in this paper by means of ray tracing simulations. These are developed based on Cassegrain-Koehler concentrators [Opt. Lett. 41(9), 1985 (2016)], with four pairs of paraboloid-hyperboloid mirrors and a central receiver composed of four Cartesian ovals of revolution. Designs at different geometrical concentrations are analyzed based on their aspect ratios (F-number). The most compact designs exhibit highest optical efficiencies. Moreover, a 3015× geometrical concentration one-cell prototype, made of aluminum and PMMA (poly(methyl methacrylate)), is fabricated and characterized indoors, achieving an effective concentration of 938 suns. This represents the CPV module with the highest geometrical concentration that has been experimentally investigated that could be found in the scientific literature.

探索基于Cassegrain-Koehler的超高聚光光伏设计，最大可达6000×

本文通过射线追踪仿真演示了超高聚光光伏（UHCPV）设计，其几何浓度高达6000倍以上，光效率达到80％。这些是基于Cassegrain-Koehler选矿机开发的。来吧 41（9），1985（2016）]，具有四对抛物面-双曲面镜和一个中央接收器，该接收器由四个直角的笛卡尔椭圆形组成。根据其长宽比（F数）分析不同几何浓度的设计。最紧凑的设计具有最高的光学效率。此外，在室内制作并表征了由铝和PMMA（聚甲基丙烯酸甲酯）制成的3015x几何浓度单电池原型，并实现了其有效浓度为938太阳。这代表了具有最高几何浓度的CPV模块，该模块已通过实验研究，可在科学文献中找到。
