Carsten Deibel, Dr. Jürgen Parisi, and Dr. Vladimir Dyakonov, “Defect Spectroscopy on Cu(In,Ga)(S,Se)2-Based Heterojunction Solar Cells: Role of the Damp-Heat Treatment”
The dashed lines show a case, where the activation energy of a defect state at the
CdS/Cu(In,Ga)(S,Se)2 interface is increased due to changes at the
interface
