Effect of Thickness on The Structure and Optical Properties of SnS Films Fabricated by RF Magnetron Sputtering
SnS thin films were prepared on glass substrates by RF magnetron sputtering technique. The crystalline structure
composition
surface morphology
film thickness
transmittance and reflectance of the films were characterized by XRD
EDS
AFM
FE-SEM and UV-Vis-NIR spectroscopy
respectively. The results show that the increase of thin film thickness helps to improve the crystalline quality and component ratio of the film
and the grain sizes and particle sizes increase with the increasing of the film thickness. The refractive index of the sample increases with the increasing of film thickness in the wavelength range from 1 500 to 2 500 nm. The samples have strong absorption in the visible light region with the absorption coefficients of 10

order. The energy bandgap (
E
g
) of the film with thickness of 1 042 nm is 1.57 eV
closes to the best optical bandgap of the solar cell materials(1.5 eV).
