Abstract

Tin sulphide films have been deposited by screen-printing method on ultra-clean glass substrate. Tin sulphide and stannic chloride have been used as the basic source material. The structural, optical and electrical properties of the films have been investigated by X-ray diffraction (XRD), reflection spectra and electrical conductivity measurement. X-ray diffraction studies revealed that the films are polycrystalline in nature, exhibiting orthorhombic structure with strong preferential orientation of grains along (111) direction. The optical band gap (Eg) of the films has been studied by using reflection spectra in wavelength range 800–1000 nm. The DC electrical conductivity of the films has been measured in vacuum by a two probe technique.
