Using Chemical Spray Pyrolysis (CSP) Technique n- type Copper doped SnS (SnS:Cu) thin films were successfully deposited onto soda-lime glass substrate. According to earlier reports (111) orientation of SnS is suggested to be the preferred orientation for PV applications. This paper reports the preparation of SnS:Cu films with (111) orientation by varying the substrate temperature which is an important parameter of CSP technique. Using X-ray diffraction, Scanning electron microscopy, UV-Vis-NIR spectroscopy and Hall measurements the Structural, Morphological, Optical and Electrical properties of SnS:Cu films are studied. The substrate temperature of 3750C is found to be the best for preparing good quality SnS:Cu thin films with preferred orientation in plane (111).
