Cu2ZnSnS4 (CZTS) thin films were deposited on glass substrates by spray pyrolysis a fast, cost effective and vacuum‐free method. X‐ray fluorescence, Raman spectroscopy and grazing incidence X‐ray diffraction, were used to characterize the obtained thin films. The analysis of these data showed a close to stoichiometry composition of the films and CZTS adopts the kesterite type structure but with poor...
Optical properties of the Cu2ZnGeS4 bulk single crystals were characterized by using Raman spectroscopy and photoluminescence spectroscopy technique. The strongest lattice vibration mode of this compound observed at 359 cm–1 and less intensive modes at 273, 291, 332, 370, 383, 405 and 414 cm–1. PL spectra of the Cu2ZnGeS4 consist of dominant broad emission band located at about 1.40 eV and a less...
