The study of the optical properties of transparent conductive oxides SnO₂:Sb, obtained by spray pyrolysis

Abstract

The study results of the dependences of the refractive index and samples transmittance of transparent conductive films of tin dioxide depending on wavelength are presented. Films with different doping levels, with different solutions volumes were synthesized on an automated installation by spray pyrolysis. It is shown that the transmittance practically does not depend on the amount of substance sprayed onto the substrate; the transmittance practically does not depend on the solution volume, but depends on the impurity concentration. The chemical composition and temperature of film deposition influence on its refractive index is established. The research results can be used in the development of technologies for the manufacture of optoelectronic structures containing transparent conductive coatings.

Graphene-Based Contacts for Optoelectronic Devices

“…This is due to its low-cost, its abundance, and its chemical stability in hydrogen plasma, in comparison with other TCOs [ 11 ]. These well-known materials have a reasonable transmittance >80% in the visible region of the spectrum [ 12 ]. In certain applications requiring limited TCO thicknesses, such as SHJ front contacts, sheet resistances are not lower than 100–120 Ohm/sq [ 13 ].…”
