A Study of the Structural and Optical Properties of Nickel Doped Aluminum and Sulfur Films and its Application on Solar Cells

Abstract

Five samples of Nix AL 2(1-x) and five other samples of NixS1-x O4 were prepared to be used as solar cell. The aim of this work is to characterize these films to see how there can used as solar cells. The crystal and Nano structure has been characterized by using X-ray diffraction technique. The optical and electrical properties where characterized using ultraviolet spectrometer. The performance as a solar cell was tested using simple electric circuit. The result for NixAL2(1-x) indicates that increasing Ni concentration X increase the energy gap while the Nano crystal size, d-spacing, mass density, absorption coefficient and solar cell efficiency decrease. For NixS1-xO4 the result obtains shoes that increasing Ni concentration increases the Nano crystal size, crystal spacing, absorption coefficient and efficiency.
