摘　　要：聚光光伏模组中,二次光学元件对增加太阳能电池接收到的入射光能量,提高聚焦光斑均匀性和增大菲涅耳透镜接收角具有重要作用。设计了一种用于聚光光伏模组的全反射式二次光学元件,用Solidworks软件建立了三维模型,结合实际工程应用,借助Zemax软件光学模拟仿真手段,对二次光学元件的倾角和高度等重要参数进行了优化。并制作了不同参数的二次光学元件,配合菲涅耳透镜、太阳能电池,搭建了实物聚光发电单元,在太阳模拟器下进行I-V性能测试,结果表明当二次光学元件高度为6 mm,上圆直径为7 mm时,太阳能电池的输出功率达到最大值720 m W,与不加二次光学元件相比,输出功率提高了16%。说明该二次光学元件对提高聚光模组效率作用显著。In concentrating photovoltaic module, employment of secondary optics can be effective in increasing the acceptance angle and incident light, as well as improving the energy uniformity of focal spot. A design of reflective secondary optics for concentrating photovoltaic module is presented. The 3D model of this design is established by Solidworks software and important parameters such as inclination angle and component height get optimized using Zemax software. According to the design and simulation results, several secondary glass prisms with different parameters are fabricated and tested in combination with Fresnel lens and multi-junction solar cell.The sun-simulator I-V test results show that the combination has the highest output power when secondary optics height is 6mm and upper circle diameter is 7 mm. The output power can reach 720 mW, which improves 16%compare to without secondary optics. It shows that secondary optics is very important in concentrating photovoltaic module.
