Direct Sputtering Deposition of a Zn 1− x Ge x O x +1 Buffer Layer With a Controllable Conduction Band for Cd‐Free Cu(In,Ga)S 2 Solar Cells

Cu(In,Ga)S 2 (CIGS) is a promising candidate material for the absorber layer in tandem solar cells, but the unfavorable conduction band offset with the conventional CdS buffer layer means that an alternative n‐type buffer layer material is required. Here, n‐type Zn 1− x Ge x O x...
