  1. Photovoltaics. Lecture 7. CIGS. From previous lecture: Cu(Inx,Ga1-x)Se2 (CIGS):. Wide energy sensitivity. Amorphous Si. E (x)[eV] = 1,02 +0,67x + 0,11x(x-1) K. Miyazaki et al., “High sensitivity and wide bandwidth Image Sensor using CuIn1-xGaxSe2 thin films” Thin Solid Films In Press, Accepted Manuscript

  2. Photovoltaics. Lecture 7. CIGS. Image sensor: spectral sensitivity K. Miyazaki et al., “High sensitivity and wide bandwidth Image Sensor using CuIn1-xGaxSe2 thin films” Thin Solid Films In Press, Accepted Manuscript

  3. Photovoltaics. Lecture 7. CIGS. 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 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”
