摘要
为了减少太阳能电池表面反射, 提高多结太阳能电池效率, 针对GaInP/GaAs/Ge三结太阳能电池和AM0光谱, 设计了折射率梯度排列的四层减反膜系结构.利用溶胶-凝胶技术, 通过对材料折射率的定向调节, 制备了折射率梯度排列的TiO2/ZrO2/酸性SiO2/碱性SiO2四层减反膜.实验结果表明, 镀膜后的三结太阳能电池在300~1 700 nm波长范围内的加权平均反射率由原先的28.58%降低至4.86%, 最高反射率由46.35%降低至15.45%.
Abstract
To reduce the reflection and improve the efficiency of multi-junction solar cell, a 4-layer antireflective coating with graded refractive index was designed for GaInP/GaAs/Ge triple-junction solar cell. Through adjusting the refractive indices of the different coatings, a 4-layer TiO2/ZrO2/A-SiO2/B-SiO2 antireflective coating with graded refractive index was successfully prepared by sol-gel dip-coating method. The results shown that the average reflectance of the triple-junction solar cell coated with the AR coatings decreased from 28.58% to 4.86 % while the maximum reflectance decreased from 46.35% to 15.45% in the wavelength range of 300~1 700 nm.
