Abstract:
Cu2ZnSnS4 and CU2ZnSnSe4 semiconductor nanocrystals were synthesized by polyol method. The morphological and structural properties were investigated by transmission electron microscopy and X-ray diffraction methods. The nanocrystals growth behavior for both compounds were compared. Showed that the synthesized nanocrystals of the four-component compounds have a single phase structure of tetragonal modification of the kesterite type. It has been found that secondary phases are not detected in the materials with the method precision. It is established that the lattice period closest to the bulk materials of stoichiometric composition has CZTS nanocrystals synthesized at a time of 60 min and CZTSe particles obtained at a synthesis time of 30–45 min. The obtained nanocrystals were used to develop nanoinks to print absorbers of solar cells by 2d and 3d printers.
