  • Apparatus and methods for fast chemical electrodeposition for fabrication of solar cells
    Patent number: 8343327
    Abstract: The invention relates generally to electrodeposition apparatus and methods. When depositing films via electrodeposition, where the substrate has an inherent resistivity, for example, sheet resistance in a thin film, methods and apparatus of the invention are used to electrodeposit materials onto the substrate by forming a plurality of ohmic contacts to the substrate surface and thereby overcome the inherent resistance and electrodeposit uniform films. Methods and apparatus of the invention find particular use in solar cell fabrication.

  • ABSORBER REPAIR IN SUBSTRATE FABRICATED PHOTOVOLTAICS
    Publication number: 20110312120
    Abstract: The invention relates generally to methods of repairing defects in thin films. Void defects in thin films are repaired using methods that take advantage of substrate manufacturing protocols rather than conventional superstrate manufacturing protocols. Methods described herein are simple, robust and compatible with existing processes and equipment used in the manufacture of superstrate devices.

  • METHODS FOR INTEGRATING QUANTUM WINDOW STRUCTURES INTO SOLAR CELLS
    Publication number: 20100273287
    Abstract: The invention relates generally to methods of fabricating photovoltaic stack structures. Methods of the invention find particular use in solar cell fabrication. The performance of a photovoltaic stack can be improved by independent control of fabrication conditions during stack formation, particularly depositing window layers after formation of absorber layers where fabrication conditions of absorber layers would otherwise detrimentally affect quantum grain structures of window layers.

  • APPARATUS AND METHODS FOR CHEMICAL ELECTRODEPOSITION ON A SUBSTRATE FOR SOLAR CELL FABRICATION
    Publication number: 20100258444
    Abstract: The invention relates generally to electrodeposition apparatus and methods. The invention finds particular use in fabricating thin film solar cells. Electrodeposition is improved by using a continuous thin film flow of electrodeposition solution between a substrate and a counter electrode, positioned in close proximity to each other, while the plating current is applied. Apparatus for carrying out methods described herein are highlighted particularly by flow manifolds that allow electrodeposition in the manner described.
