    • Methods are provided for forming a back contact for a photovoltaic cell that includes at least one semiconductor layer. One method includes depositing at least one back contact material on a metal contact. The back contact material comprises a metal nitride or a metal phosphide. The method further includes depositing an absorber layer comprising cadmium and tellurium above the back contact material and thermally processing the back contact material, such that the back contact material interacts with the absorber layer to form an interlayer that lowers a contact resistance for the photovoltaic cell. A photovoltaic cell is also provided and includes comprising a metal contact, at least one back contact material disposed on the metal contact, and an absorber layer comprising a material comprising cadmium and tellurium disposed above the back contact material. An interlayer is disposed between the back contact material and the absorber layer and comprises a compositionally graded layer of the back contact material and the absorber layer material. The photovoltaic cell further includes a window layer disposed above the absorber layer.
    • 提供了用于形成包括至少一个半导体层的光伏电池的背接触的方法。 一种方法包括在金属接触件上沉积至少一个背接触材料。 背面接触材料包括金属氮化物或金属磷化物。 该方法还包括在背接触材料上沉积包括镉和碲的吸收层,并对后接触材料进行热处理,使得背接触材料与吸收层相互作用以形成降低光伏电池的接触电阻的中间层。 还提供了一种光伏电池,其包括金属接触件,设置在金属接触件上的至少一个背接触材料以及包含设置在背面接触材料上方的包含镉和碲的材料的吸收层。 中间层设置在背接触材料和吸收层之间,并且包括背接触材料和吸收层材料的组成梯度层。 光伏电池还包括设置在吸收层上方的窗口层。
