摘要: 针对二次聚光器结构复杂、加工工艺难度大、成本高的问题,结合实际工程应用,设计了应用于密集矩阵式聚光模组的二次微棱镜,用Solidworks建立了三维模型,借助Zemax光学模拟仿真手段,对二次微棱镜的倾角和高度等重要参数进行了优化仿真,结果表明当二次微棱镜高度为5 mm、上底面边长为7 mm、工作面倾角为67.38时,太阳能电池接收的太阳辐射能量最大,达到最大值2.466 9 W,与不带二次微棱镜接收能量1.876 0 W相比,提高了31%,该二次微棱镜对提高聚光模组效率作用显著。Abstract: For the problems that secondary concentrators structure is complex, process is difficult, and cost is high, considering the actual engineering application, design of secondary microprism for dense matrix type concentrating photovoltaic module was presented. The 3-D model of this design was established by Solidworks and important parameters such as inclination angle and component height get optimized using Zemax. The results show that the combination has the highest energy when secondary microprisms height is 5 mm, upper side lengths is 7 mm and working face inclination is 67.38. The energy of solar cell surface can reach 2.466 9 W, increasing by 31% compared with that of without secondary microprisms. It shows that the secondary microprism is very important in dense matrix type concentrating photovoltaic module.
