Abstract:
Paste compositions, methods of making a paste composition, photovoltaic cells, and methods of making a photovoltaic cell contact are disclosed. The paste composition can include a conductive metal component such as aluminum, phosphate glass, phosphorus compounds such as alky! phosphate, and a vehicle. The contact can be formed on a passivation layer on a silicon wafer by applying the paste on the passivation layer and firing the paste. During firing, the metal component can fire through the passivation layer, thereby electrically contacting the silicon substrate.
Abstract:
Solder can be used to wet and bind glass substrates together to ensure a hermetic seal that superior (less penetrable) than conventional polymeric (thermoplastic or thermoplastic elastomer) seals in electric and electronic applications.
Abstract:
Glasses comprising Βi203, ZnO B203 and optionally a colorant including an oxide of a metal such as iron, cobalt, manganese, nickel, copper and chromium are suitable to form hermetic seals in solar cell modules, architectural glass windows and MEMS devices. Glass frit and paste compositions suitable for flow and bonding to various substrates- glass, metal, silicon, in the temperature range of 400-500 degrees Centigrade. The broad compositional range in mole% is 25-70% Bi203, up to 65% ZnO, and 1-70% B203. Such glasses do not have batched in alumina or silica. Such glasses lack alumina and silica.

Abstract:
Systems, apparatus and methods are provided to apply barrier and/or lubricant materials onto the interior surface of a container, such systems including a container having a chamber; a gas supply source for supplying monomer gas through a gas inlet duct having a portion extending into the chamber; a photolysis source and/or pyrolyzing surface for photolyzing and/or pyrolyzing at least a portion of the monomer gas to form a reactive gas comprising at least one reactive moiety; optionally a temperature controller for maintaining the interior surface of the container at a temperature which is less than the temperature of the pyrolyzing surface to facilitate deposition and polymerization of the reactive moiety on the interior surface of the container; and an outlet duct at the open end or a second end of the container for removing excess reactive gas from the chamber.
Abstract:
Methods are disclosed for controlling the morphology and the release-rate of active agent from coating layers for medical devices comprising a polymer matrix and one or more active agents. The methods comprise fixing the morphology or phase distribution of the active agent prior to removing solvent from the coating composition. The coating layers can be used for controlled the delivery of an active agent or a combination of active agents.
