包括含硫族化物的光伏光吸收剂的光伏装置和相关制造方法
摘要：
本公开涉及光伏装置，包括具有由至少第一区域、第二区域和第三区域界定的组成分布的含硫族化物的光伏光吸收剂。所述第二区域位于所述第一区域与所述第三区域与之间。所述含硫族化物的光伏光吸收剂的每一区域包括Cu、In、Ga、Al和至少一种硫族元素。所述第二区域中存在的Al浓度小于所述第一区域和所述第三区域中的每一个中存在的Al浓度。还公开制造这类含硫族化物的光伏光吸收剂的方法。
摘要（英）：

The present disclosure relates to photovoltaic devices that include a chalcogenide-containing photovoltaic light-absorber having a composition profile defined by at least a first region, a second region, and a third region. The second region is located between the first region and the third region. Each region of the chalcogenide-containing photovoltaic light-absorber includes Cu, In, Ga, Al, andat least one chalcogen. The concentration of Al present in the second region is less than the concentration of Al present in each of the first region and third region. Methods of making such chalcogenide-containing photovoltaic light-absorbers are also disclosed.
