In this work Cu<inf>2</inf>ZnSnS<inf>4</inf> films obtained by pulsed spray pyrolysis at T<inf>s</inf> = 673 K using a precursor contained CuCl<inf>2</inf>·2H<inf>2</inf>O, ZnCl<inf>2</inf>, SnCl<inf>2</inf>·2H<inf>2</inf>O, NH<inf>2</inf>CHNH<inf>2</inf> were investigated by X-ray diffraction, scanning electron microscopy (SEM), energy dispersive X-ray, Raman and optical spectroscopies. It was showed that the stoichiometry, structural, and optical properties of the films were altered in the broad ranges by changing the volume of sprayed precursor solution. The samples, deposited in optimal conditions, had almost single structure of kesterite, as well as stoichiometry and band gap are close to the optimal values for designing highly efficient solar cells. © 2017 Sumy State University.
