Optical spectra of CZTSSe before and after RF treatments. a 1 Ratio of reflectances for bulk CZTS processed from metallic precursors (A setup); 2 ratio of reflectances for glass/Mo/Cu/CZTSe (A setup); 3 reflectance of bulk CZTS processed from sulfide precursors (Bd setup). b Reflectance and transmittance (insert) of CZTS with respect to plasma exposure (C setup) with the steps of 1, 3, and 7. c Spectra of absorbance of CZTS thin films with (black) and without (red) RF treatment during 3 min (C setup). Insert: optical conductivity spectra of the same films
