Tin doped vanadium pentoxide thin films have been prepared by sol-gel spin coating method on FTO and glass substrate. The structural and analytical studies such as XRD, cyclic voltammetry and ac impedance spectroscopy respectively have been carried over and the results are discussed. Structural properties studied using x-ray diffrac-tion analysis reveals the amorphous nature of the vanadium pentoxide coated thin films. Cyclic voltammetry stud-ies of the vanadium pentoxide coated FTO films were carried out in the potential range of 0.8 -1.2 V, using 1M lithium perchlorate in propylene carbonate as the electrolyte. The specific capacitance of tin doped vanadium pentoxide thin film has been measured from the CV curve and it was 236 F/g. The ac impedance spectra of the film electrode in 1M LiClO4 + PC electrolyte were measured in a frequency range of 100 kHz to 0.01 Hz at a poten-tial of 0.5 V with Ag/Agcl as reference electrode. © JK Welfare & Pharmascope Foundation.
