Influence of Deposition Temperature on the Sprayed Pyrolysed In2S3 Thin Films Properties

Abstract

Films of In₂S₃ of 264-416 nm thickness were deposited onto FTO (SnO₂:F) glass, at 225-275 ^oC, by spray pyrolysis, from water: ethanol (1:1) solutions of indium(III) chloride and thiourea with molar ratio In:S = 1: 7.50. The study shows that deposition temperature has more influence on the composition (at low temperature a mixture of powder and film is obtained) and the films formation mechanism (crystal nucleation and growth), than on the structural and electrical properties of In₂S₃ thin films prepared by spray pyrolysis.
