| Abstract: | 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. |
