Abstract
A comparative study was carried out of Zns thin films deposited from sol – gel containing
Zinc Nitrate, Thiourea and Isoproponal. Zns films prepared by Dip coating and spin coating method.
Zns is an environmentally friendly material with wide band gap(Eg = 3.7 eV) compared to Cds(2.4eV),
which is conventionally used as buffer layer in chalcopyrite based solar cell. The crystal structure,
orientation and surface morphology were investigated by X-Ray diffractometer (XRD) and Scanning
Electron Microscopy (SEM). XRD pattern reveals the hexagonal structure of ZnS thin films. Optical
properties were studied using UV-visible spectroscopy. The film shows good optical properties with
high absorption and energy band gap value. These prepared films can be used for solar cell applications.
