Abstract

Improved methods and apparatus for forming thin-film layers of chalcogenide on a substrate web. Solutions containing the reactants for the chalcogenide layer may be contained substantially to the front surface of the web, controlling the boundaries of the reaction and avoiding undesired deposition of chalcogenide upon the back side of the web.
