摘要: 本文搭建了一套户外反射式聚光光伏系统，并基于光伏电池的单二极管等效电路，建立了InGaP/InGaAs/Ge三结砷化镓聚光光伏模组的数学模型，研究了模组温度为323 K，能量密度为350~500 kW/m2时的反射式聚光光伏系统的基本电学特性，并将实验计算值与理论计算值进行了对比分析。研究结果表明：峰值功率随着能量密度的增加而线性增加，而填充因子与转换效率随着能量密度的增加而减小。当模组温度为323 K，能量密度从350 kW/m2增长到500 kW/m2时，三结砷化镓聚光光伏模组的峰值功率从7.088 W增加到9.589 W，而填充因子从0.816下降到0.786，转换效率从31.64%下降到29.97%。
Abstract: Based on the equivalent circuit of the single diode, the mathematical model of the InGaP/InGaAs/Ge triple-junction solar cells photovoltaic module is established, a set of reflective concentrating pho-tovoltaic system is built. The electrical characteristics of the reflective concentrating photovoltaic system are studied when the module temperature is 323 K and the energy density is 350~500 kW/m2, and the experimental results are compared with the theoretical values. The research results show that the peak power increases linearly with the increase of energy density, while the fill factor and conversion efficiency decrease with the increase of energy density. When the module temperature is 323 K and the energy density increases from 350 kW/m2 to 500 kW/m2, the peak power of the InGaP/InGaAs/Ge triple-junction solar cells photovoltaic module increases from 7.088 W to 9.589 W, while the fill factor decreased from 0.816 to 0.786, and the conversion efficiency decreased from 31.64% to 29.97%.
