Abstract :
Reflectance spectrum calculations for a MgF2/diamond-like carbon(DLC)/DLC(or porous silicon (PS) ) silicon triple layer antireflection coating(ARCs) and the nanoporous silicon dioxide (NPSiO2) / DLC/DLC(or PS) triple layer ARCs are performed using the matrix method. The results are compared with the corresponding spectrum of a silicon oxynitride (SiOxNy)/PS, DLC/PS double layer ARCs and some triple layer ARCs, such as MgF2/Al2O3/ZnS triple layer ARCs. It is obtained that a lower reflectance in the very broad regions of the solar spectrum for the MgF2/DLC/DLC (or PS) triple layer ARCs and NPSiO2/DLC/DLC (or PS) three layer ARCs. The weighted reflectance Rw of those triple layer ARCs are 0.70% and 0.32%, respectively.
