Abstract

The Cu2Zn1-xCdxSnS4 quinternary alloy nanostructures with different Cd concentrations were grown using spin coating technique on n-type silicon (100) substrate, analysed and characterized by X-ray diffraction (XRD), Photoluminescence (PL) and Field Emission-Scanning Electron Microscopy (FE-SEM). The XRD peaks were shifted towards the lower angle side with increasing Cd concentration. The refractive index and optical dielectric constant are calculated. The electrical characterization of the Ag/n-Si/Cu2Zn1-xCdxSnS4/Ag diode through current to voltage (I–V) characterization shows the highest photo-response of (value if any) at Cu2Zn0.4Cd0.6SnS4 composition. The electrical characterization shows the highest photoresponse at Cu2Zn0.4Cd0.6SnS4 quinternary alloy.
