Abstract

Photoluminescence spectroscopy is utilized to investigate the defect chemistry of Se-deficient CuInSe//2 single crystals and polycrystalline thin films. The relationships to composition are reported, and results are categorized into Cu-rich and In-rich cases. Deconvolution is used to determine the energy positions of the various defect transitions which normally overlap in the complex PL spectral. Se-environment heat treatments provide further confirmation of the location of the Se-vacancy level, some 120-130 meV above the valence band edge. Photoluminescence spectra of thin films are reported, with donor/acceptor transitions dominating the In-rich cases. No photoluminescence is observed in Cu-rich polycrystalline thin films.
