摘要：In present work, Cu2ZnSnS4 (CZTS) thin film was successfully fabricated via a facile and novel metal-salt precursor printing route for the first time. And then the deposited sample was processed by sulfurization annealing at 600 degrees C for 30 min, successively. The sulfurized sample was characterized by X-ray diffraction (XRD), Raman spectroscopy, energy dispersive X-ray spectroscopy (EDS) and UV-vis-IR spectrophotometer. The results showed that the as-obtained sample presented as kesterite structure, stoichiometric composition, satisfactory morphology consisted of nanoparticles with size of around 400-600 nm. Meanwhile, the optical observation suggested the obtained sample had direct band gap energy of 1.4 eV, which was near optimal value for efficient solar energy conversion in a single band gap device.
