摘要
将Cu、In、Se单质粉末研磨制备了黄铜矿型的CuInSe_2(CIS)多晶粉末。研磨过程中冒出红色烟雾,发生了机械力诱导自蔓延反应(MSR)。通过实时温度监测,发现研磨初期温度变化不明显;发生反应时,温度迅速升高。讨论了MSR法制备CIS光伏材料的反应机理,并用SEM、EDS、XRD和TEM对制备的粉末进行了表征,观察和分析了样品的表面形貌、成分和组织结构。结果表明,粉末样品的颗粒尺寸小于15μm,产物为富铜的黄铜矿型CuInSe_2化合物,且为多晶态。
CulnSe2 （CIS） powders were synthesized by mechanically induced self-propagating reactions （MSR） with Cu, In and Se. The thermoelectric couple was used to detect the temperature change during the grinding process. The results showed that during the initial grinding period, the temperature rise slightly. The temperature rose rapidly after the reaction ignited. The reaction mechanism of the preparation of CIS ternary compounds by the MSR was discussed. The products were characterized by scanning electron microscopy （SEM）, energy dispersive spectroscopy （EDS）, X-ray diffraction （XRD） and transmission electron microscope （TEM）. Morphologies, compositions, and miemstmctures of the prod- ucts were observed and analyzed. The results indicated that the particle size is less than 15μm and the obtained powders are Cu-rich CulnSe2 with chaleopyrite-type structure. Characteristic peaks of the chalcopyrite-type structure such as （103） and （211） were clearly observed. The TEM analysis indicated that the products are polycrystalline.
