| Summary: | 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 . |
