Study of Structural and Optical Properties of ZnO Doped with Aluminum for Solar Cell Applications

C.H. Kalyani, I.V. Subba Reddy, P. Raju and P. Missak Swaroop Raju

Abstract

Zinc oxide (ZnO) nanoparticles were doped with aluminum (Al) in the ratio (Al: ZnO) from 0 to 10% and synthesized using the co-precipitation technique. The synthesized nanoparticles of ZnO have shown a wurtzite structure. The crystallite sizes of nanoparticles of ZnO and ZnO doped with Al, were found with the help of Scherrer’s equation. With an increase in Al concentration doping, there is a reduction in the nanoparticle’s average crystallite size. The synthesized nanoparticles were further characterized by using X-ray diffraction (XRD), ultraviolet-visible (UV-Vis) spectroscopy, and Fourier transform infrared (FTIR). The UV-Vis spectrum results of prepared nanoparticles have shown absorption values in the visible range (200 Hz – 800 Hz). Also, as the doping concentration increased, a remarkable increase in the optical band gap was observed.
