摘要
以第三代多结砷化镓太阳电池为研究对象,在太阳光仿真器下,测试不同聚焦倍率,未散热、被动铝散热片和复合散热3种散热方式下太阳电池的输出特性,分析不同光强以及不同散热方式对多结太阳电池的影响。测试结果表明:1)测试结果符合太阳电池的I-V特征曲线方程;在500倍高倍聚焦、复合散热方式下电池片效率为34.30%,比被动铝散热片条件下的高2.79%,比未散热条件下的高4.03%;2)多结太阳电池需要散热装置,在聚焦倍率大于100倍的高倍聚焦条件下,应采用复合散热方式;在聚焦倍率小于100倍的低倍聚焦条件下,可采用被动铝散热片的散热方式。
Under three different cooling methods, such as without cooling method, passive aluminum heat sink and composite heat sink system, the output characteristics of GaAs multi-junction solar cell under different concentration ratio were tested and analyzed based on the method of sun-light sources simulation. The experiment results show that the test results consist with the I-V characteristic equation. For the concentration ratio of 500, the cell efficiency under composite heat sink system is 34.30%, which is 2.79% higher than that under passive aluminum heat sink and 4.03% higher than without cooling method. The analyzing results show that GaAs multi-junction solar cells need cooling device. The composite heat sink system can be used for concentration ratio higher than 100, and the passive aluminum heat sink can be used for concentration ratio less than 100.
