    摘要: A method for forming TFPV absorber layer. A first layer including In is formed on a substrate. The first layer is partially or fully selenized to form a layer that includes InxSey. A second layer is formed on the partially or fully selenized first layer. The second layer may include multiple layers of Cu and Cu—Ga or may be a single layer of Cu—Ga. The Cu—Ga layers can be deposited from sputtering targets wherein the Ga concentration in one or more target(s) is between about 25 atomic % and about 66 atomic %. The deposition may be performed in a batch or in-line deposition system. The first and second layers are then fully selenized to form a CIGS layer.
