  • METHOD OF MANUFACTURE OF CHALCOGENIDE-BASED PHOTOVOLTAIC CELLS
    Publication number: 20160155886
    Abstract: 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.
