摘　　要：提出了一种可应用于四结GaAs太阳电池的理想减反射膜结构,经计算得出,当窗口层(AlInP)厚度为48.63nm,三层减反射膜折射率和厚度分别为2.28、1.74、1.32和63.60、83.33、109.85nm时减反射效果最佳.由TFCalc软件模拟出的反射谱表明,使用该三层减反膜的四结GaAs太阳电池在350-1800nm宽光谱范围内可获得1.82%的平均反射率.同时,分析了各膜层折射率和厚度对膜系减反射性能的影响.An ideal anti-reflection coatings structure for a four-junction GaAs solar cell is proposed.It is calculated that the refractive index and thickness of the three-layer anti-reflection coatings are 2.28/1.74/1.32 and 63.60/83.33/109.85 nm,respectively,and the optimal anti-reflection property is obtain when the thickness of the window layer (AlInP) is 48.63 nm.The reflectance spectrum simulated by TFC thin film software shows that the four-junction GaAs solar cells with the three-layer anti-reflection coatings can obtain an average reflectance of 1.82% in a wide spectral range of 350 to 1 800 nm.Meanwhile,the influences of refractive index and thickness of each film on the anti-reflection properties of the film system are analyzed.
