| Abstract [eng] |
The main focus of this dissertation is on the copper-zinc-tin sulfide thin films, their synthesis, and research. Thin films formed by sulfurizing/selenizing electrochemically deposited Cu-Sn and Cu-Sn-Zn precursor layers were investigated in the work. Different methods of electrochemical deposition of the precursor were tested and compared, including the electrochemical deposition of metals using a unique electrochemical cell produced by a 3D printer. Also, the conditions of sulfurization/selenization of the precursor layers were investigated. The phase composition and photoelectrochemical activity of the formed CTSe layers were investigated. The formed CZTS absorber layers were characterized using SEM, TEM, EDX, Raman spectroscopy, photoelectrochemical analysis, XRD, and photoluminescence analysis methods. Significant attention in the dissertation was given to determine the phase composition and the defects formed in the kesterite layer. For the first time, electrochemically formed CZTS layers were investigated by the XRD method using Cu Kα1 radiation. The kesterite crystalline structure order/disorder levels determined by Raman spectroscopy and by RSD methods were compared. |
