Abstract: A conductive paste composition contains a source of an electrically conductive metal, a first oxide component, a second, non-oxide, magnesium-containing component, and an organic vehicle. An article such as a high-efficiency photovoltaic cell is formed by a process of deposition of the paste composition on a semiconductor device substrate (e.g., by screen printing) and firing the paste to remove the organic vehicle and sinter the metal and establish electrical contact between it and the substrate.

Abstract: A conductive paste composition contains a source of an electrically conductive metal, a first oxide component comprising an alkali metal vanadium oxide composition, an optional second non-oxide, non-metal component, and an organic vehicle. An article such as a high-efficiency photovoltaic cell is formed by a process of deposition of the paste composition on a semiconductor device substrate (e.g., by screen printing) and firing the paste to remove the organic vehicle and sinter the metal and establish electrical contact between it and the substrate.

Abstract: The invention relates to a conductive paste composition useful in the manufacture of photovoltaic cell electrodes, especially electrodes contacting the p-type emitter of an n-type base cell. The paste composition may comprise a source of a conductive metal, a glass frit such as a lead borate, aluminum metal powder, and a boron source that may be at least one of elemental boron, a non-oxide, boron-containing substance, or a combination thereof, all dispersed in an organic vehicle that renders the composition suitable for screen printing or other like application method. Also provided are a semiconductor device such as a photovoltaic cell having an electrode made with the paste composition, and a method for its manufacture.

Abstract: Disclosed are aluminum paste compositions, processes to form solar cells using the aluminum paste compositions, and the solar cells so-produced. The low-siloxane aluminum paste compositions consist essentially of 0.005-2.6%, by weight of at least one siloxane; 44.5-84.9%, by weight of an aluminum powder; 0.05-5.8% of an optional indium-free additive; and 15-50%, by weight of an organic vehicle, wherein the amounts in % by weight are based on the total weight of the aluminum paste composition. The high-siloxane aluminum paste compositions comprise 15-68%, by weight of at least one siloxane; 25-84.9%, by weight of an aluminum powder; 0.1-10%, by weight of an organic vehicle.
