Investigation on Antireflection Coatings for Silicon Solar Cells

Abstract:

Thin-film anti-reflecting coatings can greatly reduce the optical loss by making use of phase changes, and the reflectivity depends on the refractive index of materials. TiO₂ZnS and Si₃N₄ coatings are suitable for using as single layer anti-reflecting coating on bare silicon surface, while the MgF₂/ZnS and SiO₂/TiO₂ double-layer anti-reflecting coating result in a minimum reflectance lower than 0.5% over broad spectral regions, with an average reflectance of approximately 2.25% between 400 and 1100 nm on the non-textured Si substrate. The short circuit current of silicon solar cells has significant improvement after depositing anti-reflecting coatings, and it increases the efficiency of the Si solar cells.
