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 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.
