Abstract
A deposition method which deposits a CdS buffer layer on a surface of a solar cell from a process solution including all chemical components of the CdS buffer layer material. CdS is deposited in a deposition chamber by heating the surface of the solar cell absorber to cause the transfer of heat from the solar cell absorber layer to at least a portion of the process solution that is in contact with the surface. Used solution is cooled, and replenished in a solution container and redirected into the deposition chamber.
