| Abstract: | At 4.2 K, the photoluminescence spectra of Cu(In,Ga)Se2 films irradiated by electrons with an energy of 5 MeV displayed the 0.93-and 0.79-eV bands that owe their origin to the radiative recombination of nonequilibrium charge carriers on radiation-induced defects. The position of the energy levels of the defects is determined and their nature is discussed. __________ Translated from Zhurnal Prikladnoi Spektroskopii, Vol. 72, No. 6, pp. 805–808, November–December, 2005. |
