Abstract

The cathodoluminescence (CL) spectroscopy and spectrum imaging were used to analyze Cu(In,Ga)Se ₂ thin films used in high-efficiency solar cells. The photon energy of the emission spectrum was consistent at grain boundaries with respect to the excitation density. The location of the excitation influenced the shift by decade of the emission spectrum. A model for radiative recombination to be applied to these chalcopyrite compounds was also described.
