Description 365-368
An X-ray diffractometer for structural, a UV-VIS Spectrophotometer for optical, and a unique aluminium sample holder
intended to examine the electrical properties of the synthesized SnSe thin films on non-conductive glass substrates in an
alkaline medium were used. Light shining through a transparent glass window illuminated the samples to examine their
electrical (photoconductivity) properties. The XRD results show that all of the films are orthorhombic crystals. The
concentration of the precursor affects microstructural characteristics such as micro strain, crystallite size, and dislocation
density. SnSe thin films' optical bandgap is measured using absorbance measurements. Semiconducting properties are
confirmed by measuring the electrical conductivity, which reaches its highest value at the optimal precursor concentration.
The as-grown SnSe films exhibit tunable photo response properties, which boost the practical application of the films in
photovoltaic and solar cells.
