20100055827 | Apparatus and Method For Fabricating Photovoltaic Modules Using Heated Pocket Deposition In a Vacuum - An apparatus and method for manufacturing thin-film CdS/CdTe photovoltaic modules in a vacuum environment. The apparatus deposits CdS and CdTe layers onto a substrate using heated pocket deposition, a form of physical vapor deposition (PVD) in which a material thermally sublimes from a thermal sublimation source block and is deposited onto a substrate. The thermal sublimation source block includes a pocket having a lower surface into which an array of holes is formed to house plugs of deposition material. Upon heating, deposition material sublimes from a surface of each plug of deposition material, and the surface of each plug regresses into its corresponding hole while maintaining a constant surface area. The sublimation surface area of deposition material across the pocket remains substantially constant during an extended deposition process, and the deposition material is substantially free of undesired thermal radiation from the substrate. As such, the thermal sublimation source block provides a temporally- and spatially-uniform thin film deposition rate across the lower surface of the substrate. | 03-04-2010 |
20100212725 | SYSTEMS AND METHODS FOR IMPROVED PHOTOVOLTAIC MODULE STRUCTURE - A system and method for improved photovoltaic module structure is described. One embodiment includes a photovoltaic module comprising a front substrate, a photovoltaic structure attached to the front substrate, wherein the photovoltaic structure comprises at least one photovoltaic cell, a back substrate, wherein the back substrate is spaced apart from the photovoltaic structure, and a structural component, wherein the structural component is located between the back substrate and the photovoltaic structure. In some embodiments, the structural component may be configured to provide thermal conduction between the front substrate and the back substrate, and/or the structural component may be configured to retain the front substrate and/or back substrate during breakage. | 08-26-2010 |

20100314076 | Apparatus and Method for Rapid Cooling of Large Area Substrates in Vacuum - The present invention is directed to an apparatus and method for rapid cooling of a large substrate in a vacuum environment. A first cooled plate is brought into close proximity with one surface of a flat substrate. The spatial volume between the first cooling plate and the substrate is sealed and brought to a higher pressure than the surrounding vacuum level to increase the cooling efficiency. A second cooled plate is brought into close proximity with the opposite surface of the flat substrate. A second spatial volume between the second cooling plate and the substrate is sealed and the gas pressure is equalized to the gas pressure in the first spatial volume. The equalization of the gas pressure on both sides of the flat substrate eliminates deflection of the substrate and bending stress in the substrate. | 12-16-2010 |
