Abstract

Novel coating consist of from nanoparticle NiO doped carbon thin film is explored with the optical and electrical properties was studied. This doping can help new excellent physical and chemical properties of carbon for photo-catalysis applications. Nanocomposite thin film was deposited on copper and glass substrates created by utilizing Spray Pyrolysis method. The precursor solution for the showering was blended Nanocomposite (NiO/C) with the polyethylene glycol as a colloidal. The SEM, UV, FTIR, XRD and AFM were used to check the behavior of the compositional components of the Nanocomposite and the energy gap of the Nanocomposite was computed. The reflection coefficient was determined from the measurements at room temperature in the wavelength range 400-1100 nm. Optical energy gap of Nanocomposite thin films have been estimated for the direct and indirect optical energy gap values determined and were 3.32 eV, 3.05 eV and photon energy 1.95 eV. The Nanocomposite activity under sunlight depends upon the band gap energy. Thin film of Nanocomposite NiO/C was sprained on the flat plate collector and then the useful energy was calculated from the solar energy before and after coating. The results demonstrated the coating on collector is very important to absorb solar energy that used to heat the water in domestic application. This paper has been achieved to dope carbon by nanoparticle of NiO for layer coating on flat plate collector. Results showed the efficiency of the collector increased (25%) by coating for Nanocomposite from absorption the solar energy light activity
