Conley, W. R.

Ion-plating is a vacuum metallizing process where the depositant is evaporated from a source (tungsten filament, electron beam gun, etc.) into a high frequency electric field where the material is ionized and then accelerated by a DC field toward the substrate. This process combines the high deposition rates associated with physical vapor deposition and improved adhesion without entrapment of Ar gas (as in sputtering). The ITW contract was initiated in December 1979 to investigate, develop, and demonstrate the capability to produce operational solar cells having metallizations and AR coatings deposited by gasless ion-plating, which will separately and/or in combination with a low cost encapsulation system meet the LSA project life, cost and performance goals. Under this contract ITW will also investigate the ability to deposit by gasless ion-plating AR and anti-soiling coatings on glass; said coatings to be permanent and possess 20 year durability. Progress is reported.
