Abstract
The photoluminescence and absoption spectral distribution close to the edge of
fundamental band were studied in the CdS and CdTe films components of the CdS/CdTe
heterojunctions. Recombination level energetic position was determined. The annealing of the
CdS/CdTe heterojunctions in presence of CdCl2 results in formation of new recombination
levels, revealed by a luminescent band in the energy range of 1.6-1.7 eV and by the shift of
the impurity band maximum to the red wavelength region by 50 meV.
