WERKWIJZE VOOR HET DOOR OPSTUIVEN VERVAARDIGEN VAN DUNNE METAALCHALCOGENIDEFILMS.

摘要

A low cost chemical spray deposition of metal and mixed metal chalcogenides is accomplished by spray depositing an oxide film from a mixture of a salt of the metal in solution with a water soluble hydrocarbon and water solvent. This oxide film is subjected to a heat treatment in the presence of a chalcogenide gas to induce an ion exchange process transforming the metal oxide or mixed metal oxide into the chalcogenide films of the present invention. The deposition process is used to provide efficient selective absorbing surfaces for a solar thermal energy converter. The process may further be employed to produce a thin film photovoltaic device for converting light energy into electricity.
