A kesterite Cu2ZnSn(SxSe1-x)4 (CZTSSe) thin film is fabricated on a Mo-coated glass substrate by a non-vacuum spray pyrolysis method from an aqueous precursor solution containing Cu(NO3)2, Zn(NO3)2, Sn(CH3SO3)2 and thiourea followed by sulfurization and selenization at 600°C. The fabricated CZTSSe thin film shows high crystallinity with optimal Cu-poor and Zn-rich compositions, which is confirmed by the X-ray diffraction pattern, Raman spectrum, and Energy dispersive X-ray spectroscopy results.
