| 摘要 | 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 (MoS2) 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 MoS2 layer 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. | ||

| 主权项 | 1. A method, comprising: forming a layer of copper zinc tin sulfide (CZTS) on a first layer of molybdenum (Mo); annealing the CZTS layer and the first Mo layer to form a layer of molybdenum disulfide (MoS2) between the layer of CZTS and the first layer of Mo; forming a back contact on a first surface of the CZTS layer opposite the first Mo layer; separating the first Mo layer and the MoS2 layer from the CZTS layer to expose a second surface of the CZTS layer opposite the first surface; and forming a buffer layer on the second surface of the CZTS layer. | ||
