| 초록 |
This study reports effects of process pressure on the properties of CuZnSn(SSe)(CZTSSe) thin fims. Thin films were prepared by sulfurization of evaporated precursor thin films. S and Se powder were evaporated in a graphite box during sulfurization. The process pressures were varied in a five step from 500torr to 900torr.The crystal structure and phase of sulfo-selenized absorbers were analyzed by X-ray diffraction(XRD). The phases were also confirmed by a Raman spectrometer. The surface and cross-sectional morphologies of films were observed using a Scanning electron microscope(SEM). Lastly, the chemical compositions were measured by X-ray fluorescence spectroscopy (XRF). Through these results, we discuss how to be formed CZTSSe grain growth and to prevent growing defects and secondary phases during sulfo-selenization process. |
