Cd0.5Zn0.5Se wide range composite thin films for solar cell buffer layer application
Cd0.5Zn0.5Se composite thin films were obtained on glass substrate using aqueous alkaline solution at low temperature using cadmium acetate and zinc acetate as Cd2+ and Zn2+ and Se2- ion sources. Different phases of individuals i.e. CdSe and ZnSe, spherical and needle shape surface morphology and good elemental chemical stoichiometric ratio were observed from X-ray diffraction, scanning electron microscopy (SEM) and energy dispersive X-ray analysis (EDX) studies, respectively. The band gap and electrical resistivity of the composite film were 2.35 eV and about 10(7) Q cm, respectively. (c) 2006 Elsevier B.V. All rights reserved.
