摘　　要：结合纳米材料折射率(小于1.4)和AM0太阳光谱特性,对空间硅太阳电池的减反射膜进行了设计分析.分别设计了常规材料和纳米材料的双层、三层减反射膜,得到了最佳的膜系参数,并作出了反射率变化曲线.结果发现,采用低折射率纳米材料的三层减反射膜有着更好的减反射效果,新型纳米减反射膜系与采用常规材料的减反射膜系相比,优化后的最小加权平均反射率减小了15%(双层减反射膜)和24.5%(三层减反射膜).According to refractive indexes of nanomaterials （less than 1.4） and the AM0 solar spectrum, antireflection coatings of space Si solar cells are designed and analyzed. For double-layer and tri-layer antireflection coatings fabricated by normal and nanometer materials, the optimal parameters of coatings and refection coefficient curves are obtained. The double-layer and tri- layer new nano antireflection coatings are optimized, and have better antireflection compared with those fabricated using the normal materials. It is interesting that, after optimizing, the minimal weighted reflectance of the new nano antireflection coatings is 15% and 24.5 % less than that of the normal antireflection coatings for the double-layers and the tri-layers, respectively.
