对太阳能聚光光伏发电技术中的聚光系统进行了研究，分析了菲涅耳透镜应用于太阳能聚光器的优点、聚光特性以及光学效率，推导并获得了平面向外、菲涅耳面向太阳电池的点聚焦菲涅耳透镜的设计公式。在ZEMAX软件的非序列模式中实现了基于非成像光学理论的光线追迹仿真，对某一尺寸的菲涅耳透镜的焦平面上光斑能量分布情况进行了分析与模拟。研究结果表明，利用通常的菲涅尔透镜实现聚光作用的聚焦光斑的光能量主要集中在太阳电池的中心部位，呈现为从中心往外围能量越来越弱的同心圆环。要使太阳电池接收到的光能量尽可能均匀，则需要增加二次聚光元件。

The concentrator in solar concentrated photovoltaic system was studied. The advantages of Fresnel lens for solar concentrator and its focusing characteristics and optical efficiency were analyzed, and the designing formula of point focus Fresnel lens with flat surface outward and Fresnel surface facing to the solar cell was obtained. Based on the theory of non-imaging optics, the ray trace simulation was realized in the non sequence model of ZEMAX software, and the solar energy distribution on focal plane of Fresnel lens for a certain size was analyzed and simulated. The simulation results show that, the solar energy of focused facula generated by usual Fresnel lens mainly focuses on the centre of the solar cell, and as the distance from the centre increases, the energy density of the concentric rings decreases. To make the solar energy distribution of the solar cell even, the second concentrator in concentrated Photovoltaic should be added.
