Electrodeposition of copper indium diselenide from an acidic buffer solution (the glycine media)
Written by sctunisie no commentsCopper indium diselenide electrodeposition in thin films is studied in an electrolyte consisting of a glycine / glycinium (NH3–CH2–COOH+ / NH2–CH2–COOH) buffer solution. Compared with the currently used sulphuric acid electrolyte, the use of a buffer makes easier the indium insertion, especially when the solution is poorly stirred. This is explained by the fixation of the pH near the electrode that impedes the hydrolysis of In3+ ions.
