摘要
A two-stage selenization method for preparing CuInSe2 thin films in a carrier-gas (nitrogen) flow is developed. The dependences between the morphology and structure of CuInSe2 thin films and the selenization temperature are studied via electron microscopy and X-ray diffraction analysis. It is demonstrated that the film incorporates copper and indium selenides in the temperature range 300°C ≤ T < 400°C and a stoichiometric film with ordered chalcopyrite is formed at Т = 400°С. The possible mechanism whereby a CuInSe2 thin film is generated with the participation of selenization centers, namely, Cu2Se and In2Se3 grains, is discussed. © 2016, Pleiades Publishing, Ltd.
