Turkish Journal of Physics

Antireflection coating on silicon, a high refractive index substrate, was theoretically investigated. The effects of antireflection coating on electrical parameters such as the short circuit current, open circuit voltage, maximum current density, maximum voltage, maximum power, power density, and conversion efficiency of the solar cell were simulated. Various previous works in which solar cell efficiencies were investigated after applying double layer antireflection coating (DLARC) were reviewed. Ti$_{2}$O$_{3}$ and MgF$_{2}$ were then applied in a DLARC design, taking into consideration the refractive index dispersion of the two materials. The results were compared with other works in the solar spectral range (400-1200 …
