In this work, thin films of Cu2ZnSnS4 (CZTS) were grown by spray-pyrolysis method and were irradiated by pulsed Nd: YAG laser. Their morphological, chemical, structural and substructural characteristics were investigated using AFM, SEM, EDS, XRD and Raman spectroscopy. Upon laser irradiation, improvement of crystallinity, stoichiometry and surface morphology were observed in the obtained CZTS thin films with the normal distribution of newly-formed particles throughout the plane. It was shown that the laser processing by pulsed Nd: YAG laser is an alternative method to the traditional post-growth thermal annealing and can be used not only for local annealing but also for annealing in various depths in the films.
