Theoretically optimized triple layer antireflection coating can be replaced with four layer LHLH structure around the designed wavelength. In this paper, triple layer and its four layer equivalent structure have been utilized as antireflection coating of GaAs solar cell and the reflectance coincidence of these structures is proved. The wavelength of 650nm has been assumed for design of multilayer structure. Also, the six layer antireflection coating is made with inserting one more HL pair in the structure. We design multilayer structures by introducing X parameter which describes 4- and 6-member set of thicknesses and finding the optimum combination of thicknesses. Simulation results confirm that the optimum case of six layer structure presents better performance in comparison with the best case of four layer coating.
