Abstract:
The optimization of a SiO_2/TiO_2,SiO_2/ZnS double layer antireflection coating(ARC)on Ga_(0.5)In_(0.5)P/In_(0.02)Ga_(0.98)As/Ge solar cells for terrestrial application is discussed.The Al_(0.5)In_(0.5)P window layer thickness is also taken into consideration.It is shown that the optimal parameters of double layer ARC vary with the thickness of the window layer.
