摘　　要：利用砷化镓聚光太阳电池设计制作建筑一体化高倍(500倍)聚光光伏组件,采用TracePro软件对组件光学性能进行了模拟分析,同时对组件光、电特性进行了实验检测。模拟结果表明经一次聚光后光斑尺寸为15 mm×15 mm,二次聚光器的能量损失为4.1%,跟踪误差在±0.5°以内时对组件聚光效率影响较小,组件聚光效率达到78.1%;实测结果表明跟踪误差为±0.5°的情况下,一次聚光后光斑实际尺寸为25 mm×25 mm,导致部分能量未汇聚到二次聚光器上,因此实测聚光效率为69.0%;聚光电池的实测发电效率保持在37.9%,组件的系统运行效率保持在26.1%。A building integrated 500×solar concentrating photovoltaic module using GaAs solar cell is designed and made.The optical property of the module is simulated and analyzed using TracePro software.The optical and electrical properties of the module are tested experimentally.The simulation results show that the focal spot size of the primary concentrator is 15 mm×15 mm,and the energy loss of the secondary concentrator is 4.1%.The effect of tracking error on the concentrating efficiency can be ignored if tracking error less than±0.5°,and the corresponding concentrating efficiency can reach 78.1%.The test results show that the actual focal spot size of the primary concentrator is 25 mm×25 mm under tracking error of±0.5°,which means that part of the energy is not concentrated on the secondary concentrator,therefore the actual concentrating efficiency is 69.0%.The generation efficiency of solar cell is maintained at37.9%,and the system operation efficiency of the module is maintained at 26.1%.
