Solar energy is being used at different applications and is proving to be a major renewable source of energy. The photovoltaic cells used in CPV are costly and less efficient. The recurrent method of the concentration of light by means of parabolic reflectors has a lot of drawbacks. The most efficient way to concentrate solar energy is to use a Fresnel lens for the full use of sunlight aspect ratio. In this work, Fresnel lens design parameters are studied and simulated. The temperature change in outside operation conditions has been recognised during design stages. After that, an analysis of the focal length change is carried out via simulation. To reduce the chromatic aberration behaviour due to the dispersion relationship between the material's refractive index and wavelength, it was assumed that each Fresnel lens groove has a varied wavelength design. The golden wavelength approach was used to determine the optimal wavelength design in the 0.54 m to 1.04 m range of the optimum solar spectrum. The results obtained are encouraging. It was found that the method of selecting different wavelengths for each concentric ring improves the flux distribution as well as the dispersion of the solar spectrum. © 2021
