Structural, electrical and photoelectrochemical properties of calcined SnO2/TiO2 nanocomposite films for solar cell applications

In present work, one dimensional rutile-TiO₂ nanoarrays were grown directly on transparent conductive Fluorine-doped SnO₂-coated (FTO) glass substrates by chemical bath deposition (CBD) method using Titanium (III) chloride as the precursor, followed by calcination. The heat treatment leads to the considerable changes in structural, optical and electrical properties of nanostructure synthesized materials. The simplicity of deposition of rutile-TiO₂ nanoarrays at low temperature provides a new insight for potential applications in solar cells, sensors, catalysis and separation technology.
