Abstract Highlights: • CIGS thin film was electrodeposited on a molybdenum (Mo) electrode from a non-pH buffered chloride-based electrolyte. • The electrodeposited time and the concentration of In{sup 3+} control the growth of CIGS thin film prepared in this electrodeposition system. • The kinetic of electrodeposition system was gradually dominated by the diffusion process with the electrodeposition time. - Abstract: In this study, the electrochemical impedance spectroscopy (EIS) technique was used to investigate the electrochemical behavior of the interface between the Mo electrode and the Cu-In-Ga-Se electrolyte. In this electrodeposition system, the main parameters include (1) various deposition times, and (2) the effect of In{sup 3+} concentration on the diffusion processes, electrical double layer, charge transfer resistance, and Warburg impedance. Experimental results revealed that the electrochemical kinetic behavior of CIGS thin film is strongly influenced by (1) the electrical double layer existing between the substrate, and (2) the electrolyte with different concentrations of In{sup 3+}. With an increase in the electrodeposition time, the kinetic behavior of this electrodeposition system was gradually dominated by the diffusion process rather than charge transfer process.
