Abstract

The ternary Cu-In-Se system was prepared from an aqueous solution containing CuC2 , InCl3, H2SeO3 complexed by citrate (Na3C6H5O7). The kinetics of electrodeposition were studied by using the rotating disk electrode method (RDE). X-ray diffraction showed the formation of CuInSe2 films, of chalcopyrite structure, at potentials ranged between -0.95 V and -1.12 V (vs.SSE). The composition of the deposited films was studied by energy dispersive analysis of X-rays (EDAX) and Rutherford backscattering spectroscopy (RBS). From the results, it was found that stoichiometric chalcopyrite CuInSe2 was obtained by controlling bath composition, deposition potential, solution temperature and pH.
