Abstract:
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 elastically shaped by a series of shaping rollers to retain the process solution on the solar cell absorber layer and while the flexible workpiece is heated by contacting to a heated liquid that the shaping rollers are fully or partially immersed. The flexible workpiece is elastically shaped by pulling a back surface of the flexible workpiece into surface cavity of the shaping rollers using magnetic force.
