[10a-PB3-13] An approach of Investigating Characteristics with Terahertz spectroscopy of
Cu-Zn-Sn-S (CZTS) and Cu-Sn-S (CTS)
Keywords:Terahertz Spectroscopy, Semiconductor
In this study, polyethylene is mixed with CZTS and CTS crystals prepared by the iodine transport method using broadband, high resolution, variable frequency THz spectrometer, pelletized as a base material, THz absorption spectrum is measured, and investigation of its absorption peak etc By doing so, we aim to propose it as a new solar cell material evaluation method.
The THz transmission spectrum of the CZTS crystal was measured and it was confirmed that THz absorption peaks existed at 2.55, 2.75, 4.47, 5.11 THz in both 15.5 wt% and 41.6 wt% samples.
