Abstract


Cu2ZnSnS4 nanoparticles have been produced by a facile and high-yield wet-chemical method at low synthesis temperature. In order to remove the organic residues the synthesis was followed by a pre-annealing procedure at 250 degrees C in nitrogen atmosphere. Data evaluation of ex-situ XRD measurements on the pre-annealed sample showed, that the diffraction pattern of the as-synthesized powder can be well modeled by diffraction of a hexagonal and a disordered cubic CZTS structure. The CZTS nanoparticles were annealed under nitrogen atmosphere up to 550 degrees C without and with the addition of selenium powder and diffraction patterns were recorded in-situ as a function of temperature in order to investigate the structural phase transitions during the re-crystallization and selenization of the powders. The in-situ XRD measurements showed a structural phase transition into the tetragonal CZTS structure for pure CZTS and with the addition of selenium. With the addition of selenium, an exchange reaction between sulfur and selenium during the heating process was observed by the shift in the diffraction peaks and subsequent refinement of the lattice parameters of the crystal structures.
