  • Reflectivity spectra of Cu2ZnSnSe4 
    BODNAR, I.; DERMENJI, L.; GUC, M.; LEVCENCO, S.; ARUSHANOV, E.; SYRBU, N. N. (Institutul de Fizică Aplicată al AŞM, 2012)
    Thin film solar cells of Cu2ZnSnSe4 with efficiency exceeding 9 % have been fabricated so far. In this paper we present reflectivity spectra measured at 300 K in the photon energy range of 1.5 - 6 eV. Cu2ZnSnSe4 crystals ...
  • Temperature dependence of the optical gap CuGa5Se8 
    NATEPROV, A.; LEVCENCO, S.; SYRBU, N. N. (Institutul de Fizică Aplicată, AŞM, 2006)
    The investigation of the absorption coefficient spectra below the fundamental edge of ordered vacancy compound CuGa5Se8 was studied early for samples prepared by Bridgman method. Compositional measurements were carried out ...
