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

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
