Abstract

Selectively absorbing properties of indium tin oxide(ITO) thin film were characterized in UV-VIS-NIR wavelength regions. Sodium diffusion from glass pane had a bad influences on the properties of ITO layers. So silica-zirconia barrier layers were formed by sol gel dip coating. ITO films on buffer layered glass pane were formed by sol gel dip coating. Transmittance and reflectivity dependence on the thickness of barrier layer and ITO coating layers were studied by measuring sheet resistance and UV-VIS-NIR spectroscopy.

Transparency at 550 nm wavelegth and selective reflectivities were important to apply to passive solar collectors. In single barrier layer and six-fold ITO coated films, good selectivities were obtained. Homogeneity of indium tin precursor coating solution was important. Atmosphere condition (humidity, temperature), dip and drawing conditions were also additional factors for uniformity of films.
