Nano Conducting Particles Based Antireflection Coating for Silicon Solar Cells

An attempt has been made to investigate the effect of antireflection coating containing aluminum nanoparticles over the layer of silicon nitride on silicon surface. In this regard numerical calculations have been performed to obtain reflectance for varying radius (i.e., 50 nm, 62.5 nm and 70 nm) as well as periods (i.e., 100 nm, 110 nm 125 nm, 250 nm and 300 nm) of Al-NCPs using transfer matrix method (TMM). The refractive index of nanoparticles under consideration is wavelength dependent. Inclusion of metal nanoparticles in the antireflection coating has reduced reflectance significantly. Calculated reflectance has been used as an external file in PC1D simulator to study the performance of silicon solar cells.
