Abstract

Improved methods and apparatus for forming thin-film buffer layers of chalcogenide on a substrate web. Solutions containing the reactants for the buffer layer or layers may be dispensed separately to the substrate web, rather than being mixed prior to their application. The web and/or the dispensed solutions may be heated by a plurality of heating elements.
