Claims6
An apparatus for manufacturing a photovoltaic device comprising a means for providing a vertically oriented substrate to a first reaction zone;
- a plurality of reaction zones including at least a zone capable of providing an environment for deposition of a back contact layer;
- a zone capable of providing an environment for depositing a p-type semiconductor layer;
- and a zone capable of providing an environment for depositing a n-type semiconductor layer.
A method for manufacturing a photovoltaic device comprising providing a means capable of vertically holding a substrate, in sequence to a plurality of reactor zones wherein said plurality of zones includes at least one zone depositing a p-type semiconductor layer.
A method for manufacturing a photovoltaic cell comprising:
- a. providing a plurality of vertically disposed substrates;
- b. depositing a conductive film on the surface of said plurality of substrates;
- c. wherein the conductive film includes a plurality of discrete layers of conductive materials;
- and
- d. depositing an n-type semiconductor layer on an p-type absorber layer forming a p-n junction.
