Abstract

In this study, we report Cu₂ZnSn(S,Se)₄ (CZTSSe) thin films synthesized by using a rapid thermal annealing process of direct current sputtered precursors under a sulfur and selenium atmosphere. X-ray diffraction and Raman spectroscopy investigations showed formation of CZTSSe absorber layer without any secondary phase. X-ray fluorescence spectroscopy showed a stoichiometric absorber layer has been formed which is suitable for use in solar cells. The best thin film solar cell of CZTSSe showed a photovoltaic performance of 5.2% efficiency (V_oc: 585.0 mV, J_sc: 17.0 mA/cm² and FF: 52.0%). This is the highest efficiency reported for CZTSSe prepared from sputtered Cu/Zn/Sn precursors followed by sulfo-selenization using powder sources.
