The deposition was performed with the substrate temperature at 220℃ and the chamber pressure at 6.5 x 10-2 Pa. Argon plasma was investigated with a Langmuir probe. The plasma density and the electron temperature increased with the increasing of the discharge power. The impact oflCP discharge power on the structural and morphological properties of the CZT film were investigated with energy dispersive X-ray spectrometers （EDS）, X-ray diffraction （XRD）, and scanning electron microscopy （SEM）. XRD and EDS were combined to investigate the structure of the film. The results show that Zn loss exists during the evaporation and the loss can be reduced by increasing the ICP discharge power. From the observation on the scanning electron microscope, the grain size becomes larger with argon plasma＇s assistance. The preparation of the Cu2ZnSnS4 （CZTS） film and the measured properties demonstrate that the ICP would optimize the growth of the film.展开更多
