In present work an attempt has been made to select material to design double layer antireflection coatings (DLARC) for silicon solar cell, theoretically. In this regard, silicon nitride (Si3N4) is used along with MgF2 and SiO2 to design DLARC to achieve zero reflectance over wide range of spectra. Reflection spectra for DLARC systems of MgF2/Si3N4 and SiO2/Si3N4 have been evaluated numerically using transfer matrix method (TMM). Further, reflectance for MgF2/Si3N4 is investigated at various monitoring wavelengths (o = 550, 600, 650 and 700 nm). Calculated reflectance has been used in PC1D simulator to study the effect of double layer antireflection coating on optical and electrical parameters of silicon solar cell. Simulation results shows, reduction in reflectance form > 30% down to zero in the wavelength range 500 – 700 nm with conversion efficiency 21.33% at 600 nm for MgF2/Si3N4.
