TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Components: The reducing agent additive is selected from derivatives of hypophosphorous acid, lithium amide, and/or lithium borohydride.    TECHNOLOGY FOCUS - INSTRUMENTATION AND TESTING - Preferred Components: The metal component is selected from solder, connecting wires, transparent conductive oxides, cross ribbons, bus bars, conductive paste, metal conductive coatings, other electrical connections, and metal reflector film; and is a silver component. Preferred Process: The additive(s) is/are applied by a method selected from wiping, brushing, painting, dip coating, extrusion or co-extrusion coating, air knife coating, bar coating, squeeze coating, impregnating, reverse roll coating, transfer roll coating, kiss coating, casting, spraying, spin coating, Dahlgren, thermal transfer printing, silk screen, lithography, flexographic, gravure and inkjet printing, doctor blade, dye sublimation, xerography, offset printing, intaglio, and screen printing. The process further involves step of stacking the solar cell assembly and the polymeric encapsulant layer to form a pre-press assembly. The pre-press assembly comprises a substrate or superstrate comprising thin film solar cells, the polymeric encapsulant layer, and an outer protective layer; or the pre-press assembly comprises an outer protective layer, the polymeric encapsulant layer, a solar cell assembly, a second polymeric encapsulant layer, and a second outer protective layer. The process further involves a step of laminating the pre-press assembly to form the solar cell module. The lamination is carried out in autoclave or non-autoclave process.
