Abstract
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-
1200nm) 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 .
