摘要:
A method and apparatus for depositing a film on a substrate includes introducing a material and a carrier gas into a heated chamber. The material may be a semiconductor material, such as a cadmium chalcogenide. A resulting mixture of vapor and carrier gas containing no unvaporized material is provided. The mixture of vapor and carrier gas are remixed to achieve a uniform vapor/carrier gas composition, which is directed toward a surface of a substrate, such as a glass substrate, where the vapor is deposited as a uniform film.

An apparatus is provided for vapor deposition of a sublimated source material as a thin film on discrete photovoltaic (PV) module substrates conveyed in a continuous non-stop manner through said apparatus. The apparatus includes a vapor deposition head configured for receipt and sublimation of a source material, and for distributing the sublimated source material onto an upper surface of substrates conveyed through a deposition area. A roll seal configuration is provided at each of an entry slot and an exit slot for the substrates conveyed through the apparatus. The roll seal configuration further includes a cylinder rotatably supported at a defined gap height above a conveyance plane of the substrates such that the cylinder is not in continuous rolling contact with the substrates within the window of finished active semiconductor material. The cylinder is floatable in a vertical direction relative to the conveyance plane of the substrates such that the cylinder rolls up and over surface variations in the substrates that exceed the gap height as the substrates are conveyed under the cylinder.

The invention is a method of forming a cadmium sulfide based buffer on a copper chalcogenide based absorber in making a photovoltaic cell. The buffer is sputtered at relatively high pressures. The resulting cell has good efficiency and according to one embodiment is characterized by a narrow interface between the absorber and buffer layers. The buffer is further characterized according to a second embodiment by a relatively high oxygen content.
