Abstract: Provided are novel photovoltaic module electrical connectors, photovoltaic assemblies including these connectors, and techniques for installing these connectors to sealed photovoltaic modules. According to various embodiments, the connectors have conductive contact tips that are configured to pierce through a module exterior and form an electrical connection to the photovoltaic cells sealed inside. In certain embodiments, the novel photovoltaic module electrical connectors can be positioned at any location along one or more edges of a module to establish an electrical connection to any cell of the module. The conductive contact tips establish mechanical contacts with contact layers inside the modules, and in certain embodiments partially or completely penetrate the contact layers, without shorting the photovoltaic cells. In certain embodiments, the connectors have positive stop features that control penetration distances of the conductive contact tips into a module.

The assemblies include multiple flexible photovoltaic (PV) modules that are electrically connected and individually sealed. The modules may be sealed using a flexible material that provides protection from the environment and/or mechanical support to the cells and modules. These assemblies can be bent and even rolled. Each PV module is individually sealed with a cut-off area is provided between two consecutive modules for separating the modules. The design allows separating any number of modules from a roll without compromising any module. The modules are electrically interconnected with each other while in the roll. As such, when a set of modules is separated from a roll, all modules in a set are electrically interconnected as well as having an integral mechanical structure. The assemblies allow easy cut-to-fit installation on rooftops or other points of installation.

Abstract: An exemplary method and apparatus for abating reaction products from a vacuum processing chamber includes a reaction chamber in fluid communication with the vacuum processing chamber, a coil disposed about the reaction chamber, and a power source for supplying RF energy to the coil. The coil creates a plasma in the reaction chamber which effectively breaks down stable reaction products from the vacuum processing chamber such as perfluorocarbons (PFCs) and hydrofluorocarbons (HFCs) which significantly contribute to global warming. According to alternative embodiments, the plasma may be generated with grids or coils disposed in the reaction chamber perpendicular to the flow of reaction products from the vacuum processing chamber.
