Preparation and Characterization of Electrodeposited CuGaxIn1-xSe2 Thin Films

Abstract

CuGa _x In_{1- x} Se₂ thin films have been obtained on SnO₂-coated glass by the electrodeposition method from aqueous solution. The electrodeposition was carried out at various pH of electrolyte and cathode potential. The compositional, structural and optical studies were carried out by a scanning electron microscope (SEM), an energy-dispersive X-ray microanalyzer (EDX), X-ray diffractions, Raman scattering measurements and transmissivity measurements. The X-ray diffraction study confirmed that the electrodeposited films are single-phase solid solutions and have a chalcopyrite structure for the composition x ≤0.67.
