Persistence Photo Conductivity (PPC) in Ni-doped Cadmium Sulphide [Cd1−xNixS, (x=0, 0.03, 0.05 and 0.20)] thin films were investigated. While the morphology of the films prepared by Spray Pyrolysis Technique (SPT) were studied using Atomic Force Microscopy (AFM), the PPC has been studied using a low temperature two probe resistivity set up with a photo-diode excitation. Note worthy changes in the morphology were observed upon Ni substitution and is attributed to the strain induced upon substitution. The simple resistivity analysis shows an evolution to a highly resistive state upon increasing the Ni content and may be attributed to the local oxide formation. Ni doping enhances the photo sensitivity of the films that may be tuned for technological applications.
