N2 - In this paper, the superstrate-type silicon-based tandem cells between air and glass are added to a porous SiO 2/MgF 2 double-layer anti-reflective (DLAR) thin film structure in order to improve the glass substrate low reflectivity in a wide spectral range (400-1200nm), without high reflectivity in the near-infrared region. Practical discussion is presented, as well as experimental results of fabricated films and devices. Application of the experimental porous SiO 2/MgF 2 DLAR thin film to conventional silicon-based tandem solar cells results in improvement of the short-circuit current density by 6.82%. Solar cell efficiency is improved by 7.14%. The presented experimental porous SiO 2/MgF 2 DLAR thin film structure provides anti-reflective results in a broad range of visible light, without high reflectivity at near-infrared wavelengths.
