A chalcogen-resistant material including at least one of a carbon nanotube layer and a high work function material layer is deposited on a transition metal layer on a substrate. A semiconductor chalcogenide/kesterite material layer is deposited over the chalcogen-resistant material. The carbon nanotubes, if present, can reduce contact resistance by providing direct electrically conductive paths from the transition metal layer through the chalcogen-resistant material and to the semiconductor chalcogenide material. The high work function material layer, if present, can reduce contact resistance by reducing chalcogenization of the transition metal in the transition metal layer. Reduction of the contact resistance can enhance efficiency of a solar cell including the chalcogenide semiconductor material. |
