摘要

Cu2NiSnS4 nanoparticles were prepared for the first time using a facile solid-phase process at a temperature of 180 ℃.The crystalline structure,morphology and optical properties of the Cu2NiSnS4 nanoparticles were characterized by means of X-ray diffraction (XRD),field emission scanning electron microscopy (FESEM),transmission electron microscope (TEM) and ultraviolet-visible (UV-vis) spectrophotometer.The band gap and conversion efficiency of Cu2NiSnS4 nanoparticles were studied at various temperature.The results showed that the Cu2NiSnS4 nanoparticles exhibited an optimum band gap of 1.58 eV and a conversion efficiency of 0.64％ at 180 ℃,indicating that it maybe be useful in low-cost thin film solar cells.
