OPTICAL CHARACTERITICS OF ANTIREFLECTION COATINGS BASED ON Al2O3–SiO2 FOR SILICON SOLAR CELLS
Abstract
We present the results of the numerical modeling of the Al2O3-SiO2 single layer composite antireflection coating for silicon solar cells, its manufacturing and investigation of the reflection integrated coefficient RS £10 %. It is shown that when the concentrations of Al2O3 , SiO2 are in the ranges 52-84 % and 16-48 % (weight %), respectively, and the thickness of layers is within the 53-97 nm area, the minimum of Rs is achieved for the Al2O3 = 73-77 %, SiO2 = 27-23 % and 69-75 nm thickness. It is also shown that for layers of Al2O3: SiO2 = 75:25 % with a 72 nm thickness the value of RS is 3.53 %, which is approximately twice lower than RS for the Si3N4 coating.
