Kesterite, CuZnSnS (CZTS), is a promising absorber layer for use in photovoltaic cells. We report the use of copper, zinc and tin xanthates in melt reactions to produce CuZnSnS (CZTS) thin films. The phase of the as-produced CZTS is dependent on decomposition temperature. X-ray diffraction patterns and Raman spectra show that films annealed between 375 and 475 °C are tetragonal, while at temperatures <375 °C hexagonal material was obtained. The electrical parameters of the CZTS films have also been determined. The conduction of all films was p-type, while the other parameters differ for the hexagonal and tetragonal materials: resistivity (27.1 vs 1.23 Ω cm), carrier concentration (2.65 × 10 vs 4.55 × 10 cm) and mobility (87.1 vs 11.1 cm V s). The Hall coefficients were 2.36 × 10 versus 13.7 cm C.
黄铜矿（CuZnSnS，CZTS）是一种很有前景的用于光伏电池的吸收层材料。我们报道了在熔融反应中使用铜、锌和锡的黄原酸盐来制备CuZnSnS（CZTS）薄膜。所制备的CZTS的相取决于分解温度。X射线衍射图谱和拉曼光谱表明，在375至475°C之间退火的薄膜是四方相的，而在温度<375°C时得到的是六方相材料。还测定了CZTS薄膜的电学参数。所有薄膜的导电类型均为p型，而六方相和四方相材料的其他参数有所不同：电阻率（27.1对1.23Ω·cm）、载流子浓度（2.65×10对4.55×10cm）和迁移率（87.1对11.1cm²V⁻¹s⁻¹）。霍尔系数分别为2.36×10对13.7cm³C⁻¹。
