Paper Abstract

Fluorine-doped tin dioxide layers have been producted by spraying an organic tin solution on a hot substrate. The substrates were common window glass, pyrex and black enamelled steel. Best results are obtained with black enamelled steel. Typical values of the spectral selective layer are in that case: a solar absorptance of 0.92 and a thermal emittance of 0.15. Aging tests have been carried out in air and in vacuum. In vacuum above about 250° C aging effects occur, which are related to a decrease of the-Sn0-fraction of the layer. The effect of sodium, which can diffuse from the glass substrate into the layer, is also investigated. Experiments show that only unrealistic high concentrations of sodium give significant changes of the properties of the layer.
