摘　　要：为探究反射式高倍聚光系统中电池位置和角度对电池表面能量密度均匀性和光接收率的影响。设计并搭建了一套反射式高倍聚光系统,通过实验研究和光线追迹相结合的方法,对反射式高倍聚光系统进行了光路优化。并通过TracePro软件对电池表面能量密度进行了数值计算。研究结果表明:电池在(0,-2,52)处,与焦平面成45°角时,电池表面光接收率为56.63%,电池表面光斑的均匀度为72.85%,表面能量密度的分布和能量接收率综合比较最优,光电转换效率最高。In order to explore the influence of battery position and angle on the uniformity of battery surface energy density and light receiving rate in the reflective high-power condensing system,a reflective high-power concentrating system was designed and built.The optical path of the reflective high-power condensing system was optimized through the combination of experimental research and TracePro ray tracing.The surface energy density of the battery was numerically calculated by using the TracePro software.The research results show that when the cell is in the coordinate values of 0,-2 and 52 and forms a 45°angle with the focal plane,the light receiving rate on the cell surface is 56.63%,the uniformity of the light spot on the cell surface is 72.85%,the distribution of surface energy density and energy receiving rate are optimal by comprehensive comparison,and the photoelectric conversion efficiency is the highest.
