摘要: Abstract We report a novel hydrothermal route for the synthesis of Cu 2 NiSnS 4 (CNTS) nanoparticles. Structural characterization was done by X-ray diffraction (XRD) and Transmission electron microscopy (TEM) which confirmed phase crystallinity. Additional Raman spectroscopy, Energy dispersive spectroscopy (EDS), Field emission scanning (FESEM) UV–vis spectrophotometry. The band-gap 1.56 eV photo response behavior indicates that CNTS is ideal application in thin film solar cell devices. Thermoelectric study carried out first time. power factor ( P ) attains value 603×10 −6 µW m −1 K −2 at 440 K. activation energy found to be 160 meV.
