Abstract |
|
|
| Thin films of Tin Sulphide (SnS) are deposited on glass substrate at room temperature by chemical spray pyrolysis and reaction method for solar cell application. The structural, morphological and optical properties of tin sulphide thin films are analyzed by X-ray diffraction, SEM, EDAX, FTIR and UV–Vis analysis. The X-ray diffraction studies confirm that the deposited SnS films are polycrystalline structures. From the SEM micrographs, it is clear that the film possesses an almost smooth surface although some particles have been distributed on the film because of the increasing concentration. Various functional groups present in the developed thin film are investigated by FTIR analysis. The band gap energy decreases with increase in molar concentration as observed by UV–Vis studies and also it shows that the band gap decreases with the increasing particle size.
