基于几何光学原理，提出了一种应用于光伏聚光的复眼型聚光器设计方法，实现了在光伏电池上均匀照度分布。该复眼型聚光器由折射曲面、反射平面、自由曲面以及透射平面等四个曲面组成。由边缘光线原理、光线可逆原理、费马原理并结合斜率角控制法得到聚光器轮廓离散点，通过三维建模软件拟合成实体。采用光线追迹软件模拟太阳光入射到复眼型光伏聚光器。结果显示，该复眼型聚光器的几何聚光比为31×，在太阳光正入射时光伏电池表面照度均匀性为98%，平均高度为9.8 mm。

Based on the principle of Geometrical Optics (GO), a Flyeye concentrator with uniformity irradiance distribution on the solar cell in Concentrator Photovoltaic (CPV) system is presented. This Flyeye concentrator is composed of four surfaces, that is, refractive surface, mirror surface, freeform surface, and transmission surface. The discrete points of concentrator contour are solved according to edge-ray principle, ray reversibility principle and Fermat’s principle. Finally, the solid model is constructed by using 3D software. The sun light is used to simulate the incident light by ray tracing software. Results show that the proposed Flyeye concentrator is designed well by this method with a uniformity of more than 98%, Concentration Ratio (CR) of more than 31× and average thickness of 9.9 mm.
