BICON是在Fraunhofer伊势开发的两级集中器系统，它是单轴跟踪的。这款单轴跟踪系统的创新之处在于，它能够实现300倍的高几何聚光度，同时具有高光学效率（高达78%）和全年± 23.5 °的大接收角。为此，该系统使用抛物面反射镜（40·4 ×）和由复合抛物面聚光器（CPC，7·7 ×）组成的三维第二级。对于聚光器概念，特别是为了便于电池集成，开发了最大效率为25%的后排接触聚光器（RLCC）电池，并提出了RLCC电池的混合安装概念。本文对不同CPC材料的光学性能进行了测试和分析。最后，由六个串联互连的RLCC电池和六个CPC组成的小模块被集成到集中器系统中，并在室外进行测试。在真实的室外条件下，在约800 W/m2的直接辐照度下，BICON系统效率达到16.2%。版权所有© 2006约翰威利父子有限公司。
BICON is a two‐stage concentrator system developed at Fraunhofer ISE which is one‐axis tracked. The innovation of this one‐axis tracked system is that it enables a high geometrical concentration of 300 × in combination with a high optical efficiency (upto 78%) and a large acceptance angle of ± 23·5° all year through. For this, the system uses a parabolic mirror (40·4 ×) and a three dimensional second stage consisting of compound parabolic concentrators (CPCs, 7·7 ×). For the concentrator concept and particularly for an easy cell integration, rear‐line‐contacted concentrator (RLCC) cells with a maximum efficiency of 25% were developed and a hybrid mounting concept for the RLCC cells is presented. The optical performance of different CPC materials was tested and is analysed in this paper. Finally, small modules consisting of six series interconnected RLCC cells and six CPCs were integrated into the concentrator system and tested outdoor. A BICON system efficiency of 16·2% was reached at around 800 W/m2 direct irradiance under realistic outdoor conditions. Copyright © 2006 John Wiley & Sons, Ltd.
