제목 Effect of pre-annealing time and temperature on the properties of CuInS2 absorber layer prepared by sulfurization of In/Cu metallic precursors
초록 In this study, CuInS2 (CIS) absorber layer has been grown by sequential process consisting of sputtering of metals with subsequent sulfurization. The sulfurization process was performed two-step processes. First step was carried out by various sulfurization conditions such as pre-treatment time and temperature in the Ar atmosphere, and second step process was carried out at 500 oC for 1 hour under a mixture of N2 (95%) + H2S (5%) atmosphere. Effect of pre-treatment parameters such as pre-treatment time and pre-treatment temperature on the structural, morphological and optical properties of CIS thin films was investigated. The surface morphology, phase structure and composition of the layers were analyzed by Field-emission-scanning electron microscopy (FE-SEM), X-ray diffraction (XRD), Raman spectroscopy and Energy dispersive spectrometer (EDS). The absorption coefficient and the direct band gap of the films were evaluated by optical studies.
