Abstract:
1. A method of manufacturing a photovoltaic device, the method comprising; placing a substrate having a surface region at a first process station; forming a first electrode layer overlying the surface region of the substrate at the first process station using a first process; transferring the substrate to a second process station; forming a barrier layer overlying the first electrode layer at the second process station using a second process; transferring the substrate in a controlled ambient to a third process station; forming a p-type absorber layer overlying the first electrode layer at the third process station using a third process, the p-type absorber layer being characterized by a first bandgap range and a first thickness range; transferring the substrate in the controlled ambient to a fourth process station; and forming a second electrode layer at the fourth process station using a fourth process.
