Аннотация
We have analyzed the electrical and optical properties of Cu2ZnSnS4, Cu2FeSnS4, and Cu2MnSnS4 films with the p-type electrical conductivity, which were prepared by spray pyrolysis at temperature TS = 290°C using 0.1 M aqueous solutions of salts CuCl2 · 2H2O, ZnCl2 · 2H2O, MnCl2 · 2H2O, FeCl3 · 6H2O, SnCl4 · 5H2O, and (NH2)CS. The energy parameters have been determined from analyzing the electrophysical properties of the films using the model of energy barriers at grain boundaries in polycrystalline materials, and the thickness of intercrystallite boundaries has been estimated. The extent of the influence of the hole concentration p0 in the bulk of crystallites and height Eb of the energy barriers between grains on the electrical conductivity has been determined. The optical bandgap width for thin Cu2Zn(Fe,Mn)SnS4 films has been calculated based on analyzing the spectral dependences of the absorption coefficient.
