Photoluminescence (PL) has been used to determine the emission bands in Se-deficient CuInSe2 single crystals that were either Cu- or In-rich. Data are presented for n- and p-type crystals over the temperature range of 7-300°K. The interpretation of these PL data is based mainly on electron microprobe and Auger electron spectroscopy compositional measurements. The origins of these defect levels, that are used in this interpretation are proposed and discussed.
