Cu2ZnSnS4纳米颗粒及其薄膜的制备与表征
Preparation and Characterization of Cu2ZnSnS4 Nanoparticles and Films
摘要
Abstract
Cu2ZnSnS4 (CZTS) semiconductor is a promising materials for thin film solar cells. Cu2ZnSnS4(CZTS) nanoparticles were prepared via a hot-injection processing under high-purity N2 atmosphere, using Cu(acac)2, Zn(Oac)2, SnCl2·2H2O, sulfur powder as the precursors, oleylamine (OLA) as the solvent and the capping molecules. The CZTS thin films were deposited on glass substrates by drop-casting from the Sol of CZTS nanocrystals in toluene. The influence of reaction temperature on the phase structure and morphology of nanoparticles was studied. The samples were investigated by powder X-ray diffraction (XRD), Raman spectroscope, transmission electron microscope (TEM), scanning electron microscope (SEM) and UV-Vis-NIR spectroscope. The results indicated that the CZTS nanoparticles with 10 nm in size, good dispersion and an optical band gap of 1.5 eV was synthesized under the optimum reaction temperature of 260℃.关键词
