Fabrication of CdTe0.65P0.35/Si Solar Cell with High Efficiency Using Double Layer Antireflection

Abstract

In This work, solar cells have double layer coatings of CdTe0.65P0.35/Si with high efficiency have been fabricated. The electrical and optical properties of CdTe0.65P0.35/Si as transparent electrodes and anti-reflection (AR) coatings for Si-based solar cells are studied. This done by adding fabricated graded refractive index AR coatings using TiO2, and SiO2 thin films kept over 80% of transmittance. As the (AR) coating with graded refractive indices using TiO2 and SiO2 layers was applied to generic silicon-based solar cell, the current level increases nearly twice more than that of bare silicon solar cell without (AR) coatings. It is concluded that reflectance can be minimized using double layered ARCs. Within a spectral range of 400–945 nm.
