Charles Gay has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Publication number: 20080128019
    Abstract: Embodiments of the invention contemplate the formation of a low cost solar cell using a novel high speed electroplating method and apparatus to form a metal contact structure having selectively formed metal lines using an electrochemical plating process. The apparatus and methods described herein remove the need to perform one or more high temperature screen printing processes to form conductive features on the surface of a solar cell substrate. The resistance of interconnects formed in a solar cell device greatly affects the efficiency of the solar cell. It is thus desirable to form a solar cell device that has a low resistance connection that is reliable and cost effective. Therefore, one or more embodiments of the invention described herein are adapted to form a low cost and reliable interconnecting layer using an electrochemical plating process containing a common metal, such as copper.

  • Publication number: 20080128013
    Abstract: Embodiments of the invention contemplate the formation of a low cost flexible solar cell using a novel electroplating method and apparatus to form a metal contact structure. The apparatus and methods described herein remove the need to perform one or more high temperature screen printing processes to form conductive features on the surface of a solar cell substrate. The resistance of interconnects formed in a solar cell device greatly affects the efficiency of the solar cell. Solar cell substrates that may benefit from the invention include flexible substrates may have an active region that contains organic material, single crystal silicon, multi-crystalline silicon, polycrystalline silicon, germanium, and gallium arsenide, cadmium telluride, cadmium sulfide, copper indium gallium selenide, copper indium selenide, gallilium indium phosphide, as well as heterojunction cells that are used to convert sunlight to electrical power.

  • Publication number: 20080121276
    Abstract: A metal contact structure of a solar cell substrate includes a contact with a conductive layer or a capping layer that is formed using an electroless plating process. The contact may be disposed within a hole formed through the solar cell substrate or on a non-light-receiving surface of the solar cell substrate. The electroless plating process for the conductive layer uses a seed layer that includes an activation layer for electroless plating.

  • Publication number: 20080092947
    Abstract: Embodiments of the invention contemplate the formation of a low cost solar cell metal contact structure that has improved electrical and mechanical properties through the use of an electrochemical plating process. The resistance of interconnects formed in a solar cell device greatly affects the efficiency of the solar cell. It is thus desirable to form a solar cell device that has a low resistance connections that is reliable and cost effective. One or more embodiments of the invention described herein are adapted to form a low cost and reliable interconnecting layer using an electrochemical plating process containing common metal, such as copper. However, generally the electroplated portions of the interconnecting layer may contain a substantially pure metal or a metal alloy layer. Methods are discussed herein that are used to form a solar cell containing conductive metal interconnect layer(s) that have a low intrinsic stress.

  • Publication number: 20050268959
    Abstract: In one embodiment, a solar cell module comprises a plurality of solar cells interconnected as a solar cell array. An interconnect assembly electrically connects the backsides of two adjacent solar cells. The interconnect assembly may have an interconnect that electrically connects a contact point on a backside of a solar cell to a contact point on a backside of another solar cell. The interconnect assembly may further include an interconnect shield placed between the solar cells and the interconnect.

  • Patent number: 5812836
    Abstract: A data processor comprises storage (e.g., registers) for each of first, second and third values, a processor condition register for processor condition codes, and logic for decoding instructions including a specific instruction defining an operation between the first value and either the second value or the third value, the selection of the second or the third value being made by the processor in dependence on the state of said processor condition code. The invention is of particular, but not exclusive, application for the plotting of lines in a display system. In an example of a display system incorporating such a data processor, a pixel can be plotted on each processor instruction cycle.

  • Patent number: 4664665
    Abstract: The present invention is directed to an intraocular lens having a lens body which includes a primary portion and secondary portions. The secondary portions are connected to the primary portion with connect members. The secondary portions may be folded with respect to the primary portion so that a smaller perimeter for the lens body is possible during lens insertion into the eye thereby requiring a smaller incision in the cornea than is otherwise possible.
