Abstract

In this work, solar cells that have double-layer coatings of \(\hbox {CdTe}_{0.65}\hbox {P}_{0.35}\)/Si with high efficiency have been fabricated. The electrical and optical properties of \(\hbox {CdTe}_{0.65}\hbox {P}_{0.35}\)/Si as transparent electrodes and antireflection (AR) coatings for Si-based solar cells are studied. This is done by adding fabricated graded refractive index AR coatings using \(\hbox {TiO}_{2}\) and \(\hbox {SiO}_{2}\) thin films kept over 80% of transmittance. As the AR coating with graded refractive indices using \(\hbox {TiO}_{2}\) and \(\hbox {SiO}_{2}\) 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. The obtained results show that optimized double-layer ARCs can minimize reflectance within the spectral range of \(\sim \)400–945 nm, with the latter maintaining this performance over a broader spectrum of 390–1000 nm, in comparison with 45.05% reflectance for the bare solar cell.
