Abstract
tin oxide SnO
2
is a Transparent Conductive Oxide TCO
material with interesting physical properties, which
places it among the most promising materials for use in
various fields such as optoelectronics...etc.
In this work, we have prepared, undoped and In doped
SnO
2
thin films, with flowing concentrations: by
percentage Mol =
0, 1, 2, 3 and 5,
by spray pyrolysis
at
375
°C. Spectrophotometric measurements in Vis-UV
range have showed that all the films have a high
transmission of the extent of wavelengths (200-800 nm)
about 85% in the visible zone with a band gap energy
ranged in (
3.28 -3.21
) eV. The addition in doping
concentration leads to light deviation of bands
