Abstract:
Thin films of (Ag x Cu 1-x ) 2 ZnSn(S,Se) 4 (ACZTSSe), with x = 0.05 – 0.20, were deposited using the spray pyrolysis method, with subsequent annealing in S + Se atmosphere. Investigation of the chemical composition, structural properties and Raman scattering spectroscopy allowed to conclude that for thin films with up to 15 % of Ag concentration there is stable the formation of the solid solutions of ACZTSSe, while in the thin film with 20 % Ag strong compositional and phase inhomogeneities were found. Investigation of the electrical transport properties showed their insignificant change with increasing the Ag concentration up to 15 %.
