Abstract
Embodiments relate to a method including forming a layer of copper zinc tin sulfide (CZTS) on a first layer of molybdenum (Mo) and annealing the CZTS layer and the first Mo layer to form a layer of molybdenum disulfide (MoS) between the layer of CZTS and the first layer of Mo. The method includes forming a back contact on a first surface of the CZTS layer opposite the first Mo layer and separating the first Mo layer and the MoSlayer from the CZTS layer to expose a second surface of the CZTS layer opposite the first surface. The method further includes forming a buffer layer on the second surface of the CZTS layer.
