Abstract
This paper focuses on anti-reflective coatings on monocrystalline silicon solar cells and the impact of front surface texturing. The reference wavelength of silicon is =700 nm, with its optimum refractive index (n = 3.7838) and a surface reflectivity of 33%. The calculations were made on the basis of layer thickness values and refractive indices that allow the phase and amplitude conditions chosen to be respected, namely (MgF2) (SiOxNy), (SiOx), and (SiNx:H). Numerical simulations have shown low reflectivitys at the surface of the planar cell coated with a single layer, but texturing on this same alloy allows a significant reduction in reflectivity. However, the comparison of the results of silicon coated with a simple anti-reflection layer on a plane surface and the textured one gives us important differences such as: 7,05% for MgF2 /Si, 4,6% SiOx/Si, 0,6% for SiOxNy/Si and 0,4% for SiNx:H/Si.
