摘要: CuInSe2 thin films have been prepared by chemical spray pyrolysis (CSP) on glass substrate from the ethanol aqueous solution containing CuCl2, InCl3 and N,N-dimethylselenourea. Properlies of (electrical, structural, optical absorption morphological properties) systematically studied in terms temperature (T s), pH ion ratio (Cu/In) solution. Good chalcopyrite with large grains grown using neutralized (pH=4) at growth 360° C. On other hand, low values T s, Cu/In led to production sphalerite films.
