Electrodeposition of CuInSe2 (CIS) and CuInAlSe2 (CIAS) from aqueous solution has been systematically investigated by cyclic voltammetery implementing different scan rates. It has been shown that electrodeposited CIS and CIAS have been formed on the substrate through electrochemical-chemical interaction of reduces species on the substrate. From the obtained results, it could be inferred that I...
