The reflectance of a diamond-like carbon antireflection thin-film on a porous silicon is calculated using the optical matrix approach method. The result is compared to the reflectance spectrum of other antireflection films. This indicates a much lower reflectance combined with a larger energy range covering the infrared to the ultraviolet regions of the solar spectrum. It shows the interest of interfacing with the solar cell surface thin films of materials having appropriate refractive index that could reduce significantly the reflected part of the incoming solar radiation.
