摘要
针对一般聚光系统中光斑不均匀而导致电池性能下降的问题,设计并搭建了具有二级聚光器的碟式聚光光伏发电系统,介绍了系统的结构及工作原理,进行了户外实验。在相同聚光比条件下(150X),与单级聚光系统相比,三结砷化镓光伏电池的平均峰值功率为1.515 W/cm2,平均效率为29.29%,平均峰值功率和平均效率分别提高了23.32%和9.12%。
In the light of the problem that non-uniform light stains in a common photovoltaic concentration system lead to a degradation of the performance of a cell,designed and set up was a disk type photovoltaic concentration power generation system with a two-stage concentrator with the structure and working principle of the system being described and an outdoor test being conducted.At a same concentration ratio(150 X),the average peak power of a three-junction GaInP/GalnAs/Ge photovoltaic cell can be as high as 1.515 w/cm2 and the average efficiency can attain 29.29%.Compared with a single-stage concentration system,the peak power and average efficiency increase by 23.32% and 9.12% respectively.
