Synthesis and Characterization of Chemically Deposited Doped Stannate Ternary Metal Oxide Thin Films and Their Solar Energy Applications

Abstract

Nano structured ternary metal oxide thin film like ZnSnO4 have receive much attention in the last decades owing to their unique properties rendering them suitable for wide range of applications. ZnSnO4 were grown by the chemical spray pyrolysis method. Home made spray pyrolysis technique is employed to prepared thin films. ZnSnO4 film was deposited on glas substrate using aqueous solution of zinc acetate dehydrate (Zn (CH3COO)2.2H2O and Tin (11) Chloride dehydrate or Stanic Chloride pentahydrate, SnCl2.5H2O as precursor at temperature of 2000C. the concentration of Zinc was varied from 0.001 to 0.005 while that of Tin was at 0.5. The product was annealed at 1hr at 2000C to improve its crystallinity. Various investigative techniques like XRD, SEM, EDX, UV-Visible, Raman spectroscopy analysis were carried out to find out the structural, morphological, spectroscopic and other properties of the ternary oxide thin film. The synthesized ZnSnO4 is of average crystalline size nano flowered having transmittance which increases with increase in wavelength. It has various band gaps which makes it find its application in photocatalysis and DSSCs (photoanode).Self
