Spectral Response of a Monocrystalline Silicon Solar Cell: Under the Influence of the Variation of the Refractive Indices of the Antireflection Materials

Numerical simulations have shown that low reflectivity’s at the surface of planar cell coated with a single layer can be obtained. For example, for coatings Si3N4 and HfO2 materials, reflectivity values around 3% 2% respectively are Structures multilayer such as MgF2 /SiNx: H/Si, give very 1%. Thus, refractive index coating is an important parameter plays major role in optical properties materials. The closer to substrate or above substrate, higher reflectivity. silicon anti-reflective materials increase external quantum efficiency solar cell; 95% /Si /Si, there maximum incident photon flux within cell.
