Preparation and properties of photosensitive Cu3In5S9 thin films


Highly photosensitive thin films of the Cu3In5S9 compound were obtained by the method of instantaneous thermal evaporation of a substance in vacuum. Impurity photoconductivity and an impurity absorption band with a maximum at 1,15 eV were detected. It is assumed that the high concentration of impurity electronic states is due to the presence in the films of a high concentration of cation and anion vacancies in the structure of the crystal lattice.
