摘要
在聚光器和接收器之间加入“光漏斗”匀光器来实现砷化镓(GaAs)电池表面能流密度的均匀分布。根据蒙特卡洛射线法和照射在接收器表面能流密度相同的原理,设计“光漏斗”匀光器。聚光器开口半径为1600 mm,焦距为1700 mm,Tracepro仿真结果显示接收器表面能流密度的均匀度为98.51%,实验显示均匀度为95.05%,仿真值与实验值相近。根据GaAs电池输出电量最大化来确定电池芯片的布置范围,仿真结果得到在半径为36 mm内布置电池芯片,与实验值39 mm相近。
The“light funnel”is added between the concentrator and the receiver to realize the uniformity of energy density on GaAs surface.The“light funnel”is developed and designed basing on the Monte Carlo method and the same energy density on the surface of receiver.The concentrator aperture radius is 1600 mm and the focal distance is 1700 mm.The simulation results show that the uniformity of the energy density on receiver surface is 98.51%,which is similar to the experimental value of 94.51%.The GaAs’layout range was determined according to the maximum output power.The GaAs should be arranged in the are a with radius of 36mm based on simulation study,which obtains the similar result to the experimental value with 39 mm radius area.
