A study on the improved microstructure and morphology of CuInS2 absorber layer for thin film solar cells |
| 초록 |
CuInS2 (CIS) absorber thin films were prepared on soda lime glass substrates by sulfuriztion of sputtering deposited stacked Cu/In precursor thin films. The Cu-In precursor thin films were sulfurized in the mixture of H2S (5 %) + N2 (95 %) atmosphere with different post-annealing steps. The effect of different post-annealing steps such as holding times and increasing rates on the structural, compositional, chemical binding energy, optical and electrical properties of the CIS thin films were studied using FE-SEM (field-emission scanning electron microscopy), XRD (X-ray diffraction), EDS (energy dispersive spectroscopy), Raman spectroscopy, Hall measurement, respectively. The XRD, Raman, FE-SEM, Hall measurement and UV-vis results indicated that the properties of sulfurized CIS thin films were strongly related to the post-annealing steps. In particular, the microstructures of the sulfurized CIS thin films were denser without voids using post-annealing process as compared to that without post-annealing process. Further detailed analysis and discussion for effect of post-annealing steps on the properties CIS thin films will be discussed. |
