    Effects of CdS Buffer Layers on Photoluminescence Properties of Cu2ZnSnS4 Solar Cells by A. Le Donne, S. Marchionna, P. Garattini, R. A. Mereu, M. Acciarri, S. Binetti

    Published 2015-01-01
    “…Broad bands at 1.075 eV and 0.85 eV were detected for the first time under below bandgap excitation of the as-grown CZTS samples at low temperature, which were explained in terms of radiative transitions involving point defect-related levels determined in the literature by first-principles calculations. The emissions observed in the as-grown samples were monitored by both above and below bandgap excitations also in standard CZTS solar cells produced on the same layers. …”
