Patent number: 8308858Abstract: Embodiments as described herein provide methods for depositing a material on a substrate during electroless deposition processes, as well as compositions of the electroless deposition solutions. In one embodiment, the substrate contains a contact aperture having an exposed silicon contact surface. In another embodiment, the substrate contains a contact aperture having an exposed silicide contact surface. The apertures are filled with a metal contact material by exposing the substrate to an electroless deposition process. The metal contact material may contain a cobalt material, a nickel material, or alloys thereof. Prior to filling the apertures, the substrate may be exposed to a variety of pretreatment processes, such as preclean processes and activations processes. A preclean process may remove organic residues, native oxides, and other contaminants during a wet clean process or a plasma etch process. Embodiments of the process also provide the deposition of additional layers, such as a capping layer.Type: GrantFiled: January 18, 2010Date of Patent: November 13, 2012Assignee: Applied Materials, Inc.Inventors: Michael P.

Publication number: 20090014052Abstract: In a module of photovoltaic cells, a method of forming the module interconnects includes a single cutting process after the deposition of all active layers. This simplifies the overall process to a set of vacuum steps followed by a set of interconnect steps, and may significantly module quality and yield. According to another aspect, an interconnect forming method includes self-aligned deposition of an insulator. This simplifies the process because no alignment is required. According to another aspect, an interconnect forming method includes a scribing process that results in a much narrower interconnect which may significantly boost cell efficiency, and allow for narrower cell sizes. According to another aspect, an interconnect includes an insulator layer that greatly reduces shunt current through the active layer, which can greatly improve cell efficiency.Type: ApplicationFiled: September 19, 2008Publication date: January 15, 2009Inventors: Peter G. Borden, David J. Eaglesham

Publication number: 20080023065Abstract: The present invention relates to configuring and wiring together cells in TF PV modules. According to one aspect, cells are fabricated on one plane on a top surface of a substrate, with wiring patterned on a parallel plane, and vias formed to provide connections between the cell plane and wiring plane. In one embodiment, the wiring plane is on the back surface of the substrate and vias are formed through the substrate. In another embodiment, the wiring plane is on the top surface of the substrate underneath the cell plane and an insulating layer, with the vias formed through the insulating layer. In another embodiment, the cell plane formed on the top surface includes superstrate cells that are illuminated through a transparent substrate, with an insulator between the cell plane and an upper wiring plane. According to another aspect, the heavy bus bar connections in the wiring plane can carry large currents and do not block light impinging on the cells.Type: ApplicationFiled: July 25, 2006Publication date: January 31, 2008Inventors: Peter G.
