Method and apparatus for forming copper(Cu) or antimony(Sb) doped zinc telluride and cadmium zinc telluride layers in a photovoltaic device

摘要

A method and apparatus for an amount of Cu or Sb dopant incorporated into a zinc-based layer as the layer is being formed. The layer is formed over a coated substrate using an electrochemical deposition (ECD) process. In the ECD process, the bias voltage and plating solution composition may be systematically changed during the electrochemical deposition process to change the amount of Cu or Sb dopant incorporated into the plated layer.
