| 제목 | Effect of Selective Etching Solution on the Cu2ZnSn(S,Se)4 (CZTSSe) Absorber Layer |
| 초록 | Cu2ZnSn(S,Se)4 (CZTSSe) absorber thin films were prepared on Mo coated soda lime glass substrates by sulfo-selenization of sputtering deposited stacked Zn-Sn-Cu precursor thin films. The CZT precursor thin films were sulfo-selenized in the S+Se vapor atmosphere. The annealed films were further subjected to etching using a mixture of 2-mercaptoethanol and ethylenediamine solution, which is known to effect on the selective etching of Cu- based secondary phases [1]. The effect of selective etching solution (2-mercaptoethanol + ethylenediamine) on the structural, optical and electrical properties of the CZTSSe thin films were studied using FE-SEM (field-emission scanning electron microscopy), XRD (X-ray diffraction), XRF (energy dispersive spectroscopy), Dark current, SIMS (secondary ion mass spectrometry), Cell efficiency. The XRD, XRF, FE-SEM, Dark current, SIMS and Cell efficiency results indicated that the properties of sulfo-selenized CZTSSe thin films were strongly related to the etching solution. Further detailed analysis and discussion for effect of etching solution on the properties CZTSSe thin films will be discussed. References [1] Alexandre H. Pinto, Seung Wook Shin, Eray S. Aydil and R.
