Simulation of single and double anti-reflective film for solar cell

This work presents the analysis of the Fresnel reflection and transmission coefficients at normal incidence to determine an equation for the reflectivity of single and double thin films that are deposited on the reflective surface of a solar cell. The resulting expressions are simulated in the Matlab software, and it is shown how by having such a thin layer, zero reflection can be achieved at a desired wavelength and the zero reflection bandwidth can increase considerably by having a thin double layer.
