20100243046 | METHOD OF FORMING A PROTECTIVE LAYER ON THIN-FILM PHOTOVOLTAIC ARTICLES AND ARTICLES MADE WITH SUCH A LAYER - Chalcogenide based photovoltaic devices cells with good resistance to environmental elements can be formed by direct low temperature deposition of inorganic barrier layers onto the film. A unique multilayer barrier can be formed in a single step when reactive sputtering of the silicon nitride onto an inorganic oxide top layer of the PV device. | 09-30-2010 |
20110034642 | SILYLIMIDAZOLIUM SALT COMPLEXES - The present invention relates to silylimidazolium salt complexes and their uses as catalysts including tunable latent catalysts for curing epoxy resins. | 02-10-2011 |
20110168243 | MOISTURE RESISTANT PHOTOVOLTAIC DEVICES WITH EXPOSED CONDUCTIVE GRID - The present invention provides strategies for improving the adhesion among two or more of transparent conducting oxides, electrically conductive grid materials, and dielectric barrier layers. As a consequence, these strategies are particularly useful in the fabrication of heterojunction photovoltaic devices such as chalcogenide-based solar cells. When the barrier is formed and then the grid is applied to vias in the barrier, the structure has improved moisture barrier resistance as compared to where the barrier is formed over or around the grid. Adhesion is improved to such a degree that grid materials and dielectric barrier materials can cooperate to provide a hermetic seal over devices to protect against damage induced by environmental conditions, including damage due to water intrusion. This allows the collection grids to be at least partially exposed above the dielectric barrier, making it easy to make electronic connection to the devices. | 07-14-2011 |
20110192453 | MOISTURE RESISTANT PHOTOVOLTAIC DEVICES WITH IMPROVED ADHESION OF BARRIER FILM - The present invention provides strategies for improving the adhesion between a barrier region, a transparent conductive region, and/or an electrically conductive grid through the use of an adhesion promoting region. The adhesion promoting region is optically transmissive and comprises a metal layer, a metal nitride layer, a metal carbide layer, or a combination thereof and preferably comprises at least one of Cr, Ti, Ta, and Zr or a combination thereof. These strategies are particularly useful in the fabrication of heterojunction photovoltaic devices such as chalcogenide-based solar cells. Adhesion is improved to such a degree that grid materials and dielectric barrier materials can cooperate to provide a hermetic seal over devices to protect against damage induced by environmental conditions, including damage due to water intrusion. The adhesion promoting region also serves as a barrier to the migration of Na, Li, and the lanthanoid series of elements. | 08-11-2011 |
20110192454 | PHOTOVOLTAIC DEVICE WITH TRANSPARENT, CONDUCTIVE BARRIER LAYER - The present invention provides strategies for providing photovoltaic devices that are more resistant to moisture and/or oxygen degradation and the accompanying migration of key elements such as Na, Li, and the lanthanoid series of elements from the absorber layer and that have enhanced service life and improved performance. These strategies are particularly useful in the fabrication of chalcogenide-based photovoltaic devices such as chalcogenide-based solar cells. These strategies incorporate a barrier region between the photovoltaic absorber region and the front side collection grid. The barrier region keeps moisture and/or oxygen from the absorber layer and contains key elements such as Na, Li, and Ln in the absorber layer. As a result, the absorber layer retains its performance capabilities for an extended period of time. | 08-11-2011 |
