Design and Optimization of Antireflection Coating Performance for UV Spectrum by Use CdS Nanoparticles on Si Substrate
Abstract
In this study, the optical properties of CdS as a function of nanoparticle size were calculated and investigated and it's used in design theory for single-layer Antireflection coatings at a quarter wave thickness at λo in the UV spectrum range of 300-400 nm. Silicon have been selected as substrate. MATLAB language programs with version of 7.11.0 were used to describe the reflectance as a function of particle size, refractive indexes, energy gap and the wavelength at normal and oblique incidence which are depending on Brus model and Characteristic Matrix theory as a basic theory.The coating design (Air/Nano CdS/Si) by was obtained at a lower value of (0.0093%) at the incident angle of 0° with wavelength of 350 nm and particle size of (Ps = 3 nm). These coating are promising for solar cell application.
