Abstract
A process for improving the stability of a cadmium chalcogenide/copper chalcogenide photovoltaic cell is disclosed. The improvement comprises positioning a layer of a polymer composition containing electrically conductive particles between the copper chalcogenide layer and the metal electrode such that the metal electrode does not make physical contact with the copper chalcogenide layer.
Claims26
A process for improving the stability of a cadmium chalcogenide/copper chalcogenide photovoltaic cell having a metal electrode in electrical contact with the copper chalcogenide layer, which process comprises positioning a layer of a polymer composition containing electrically conductive particles between said copper chalcogenide layer and said metal electrode such that said metal electrode is not in physical contact with said copper chalcogenide layer.
A photovoltaic cell having improved stability comprising:
- (a) an electrically conductive first electrode;
- (b) a film of cadmium chalcogenide contacting said first electrode;
- (c) a film of copper chalcogenide contacting said cadmium chalcogenide and forming a p-n junction therewith;
- (d) a layer of a polymer composition containing electrically conductive particles in electrical contact with a portion of said copper chalcogenide film;
- and
- (e) a second metal electrode in electrical contact with said polymer layer but not in physical contact with said copper chalcogenide layer.
