A deposition method and a system are provided to deposit a CdS buffer layer on a surface of a solar cell absorber layer of a flexible workpiece from a process solution including all chemical components of the CdS buffer layer material. CdS is deposited from the deposition solution while the flexible workpiece is heated and elastically shaped by a heated shaping plate to retain the process solution on the solar cell absorber layer. The flexible workpiece is elastically shaped by pulling a back surface of the flexible workpiece into a cavity area in the heated shaping plate using an attractive force.

Roll-to-roll processing method and tools for electroless deposition of thin layers

The present invention relates to method and apparatus for preparing thin films of materials for various applications including electronic devices such as solar cells. In one aspect, each of the method and apparatus passing an electrical current through at least one of the base or sheet to provide controlled localized heat to the base or sheet, or to layers disposed above the base or sheet. In another aspect, the controlled localized heat is provided in combination with a process environment that can be a non-inert gas that contains an element that will become part of a compound on the base or sheet, or an inert gas that allows for the process environment to provide annealing.
