Simulation of multilayer layer antireflection coating for visible and near IR region on silicon substrate using matlab program

الملخص EN

In this work, double layer and three antireflection coating were designed and simulated, optical reflection values were deduced with a matrix formulation via a personal computer using matlab program, six materials has been selected to investigated of the reflection as function of wavelength in visible region and near IR between (400-1200 nm) on silicon substrate and central wavelength at 900nm the result show double layer quarter-quarter wave optical thickness has good preference antireflection has been reduced reflection from 32 % for silicon surface to 3 % and for three layer coatings, the results obtained broadband antireflection spectra and several form antireflection that have zero reflection in double and three layer antireflection coating.

The refractive index and the optical thickness of each layer are adjusting to optimum antireflection coatings on silicon solar cells.
