Abstract:
The invention relates to glass compositions useful in conductive pastes for silicon semiconductor devices and photovoltaic cells. The thick film conductor compositions include one or more electrically functional powders and one or more glass frits dispersed in an organic medium. The thick film compositions may also include one or more additive(s). Exemplary additives may include metals, metal oxides or any compounds that can generate these metal oxides during firing.

Abstract:
Describe are encapsulation assemblies useful for electronic device, having a substrate and an electrically active area, the encapsulation assembly comprising a barrier sheet; and a barrier structure that extends from the sheet, wherein the barrier structure is configured so as to substantially hermetically seal an electronic device when in use thereon. In some embodiments, the barrier structure is designed to be used with adhesives to bond the encapsulation assembly to the electronic device. Gettering materials may be optionally used.

Abstract:
The present invention provides a method for inducing a refractive index change in a lead silicate glass material comprising: providing a lead silicate glass material; and irradiating the lead silicate glass material to increase the index of refraction of said lead silicate glass material. The present invention also provides a photo-induced lead silicate glass grating.
Abstract:
A coating is applied to a substrate using an intermediate membrane. The coating is typically conductive or semi-conducting, and the substrate is typically glass. In one form, the coating is applied, in one or more layers, to a flat flexible membrane. The membrane is then placed on the substrate, and the combination is treated under controlled conditions in a heating chamber. The combination is first heated in a neutral atmosphere to cause volatisation of the sacrificial membrane, then successively in oxidising and reducing conditions to cause strong bonding between the coating and the substrate. In another form, a non-sacrificial membrane has a substrate contact surface which is physically and chemically compatible with the substrate and which, when treated either chemically or thermally, forms a bond with the substrate.
