Influences of alkali incorporation and electrodeposited metal layer on formation of MoS2 in CZTS thin films

Spin-coated CZTS films prepared by two different precursor mixing regimes, at room temperature and at 150 °C

“…The Raman spectra presented in Fig. 2 (b) reveal two distinct peaks for all samples attributed to A1 and A2 vibration modes: one at 283.31 cm −1 (found for 150 0 C-ST and RT-TB films), 285.24 cm −1 (150 0 C-TB) and 287.17 cm −1 (RT-ST) which arises from the vibration of Cu atoms in the CZTS crystal structure (known to appear around 287 cm −1 ) [ 23 , 24 ], and the others at 327.67 cm −1 (150 0 C-TB), 329.60 cm −1 (RT-ST), 333.45 cm −1 (150 0 C-ST) and 335.38 cm −1 (RT-TB), related to the presence of Cu, Zn, and Sn in the CZTS film [ 16 , 24 ].…”

Structural, Optical, and Optoelectrical Studies of Spray Pyrolyzed CuGaSnS4 Thin Films

“…18 The experimental procedures of synthesizing the binary, ternary and quaternary chalcogenides thin films were classified into two categories. They are the chemical methods such as spray pyrolysis, 19 chemical bath deposition, 20 sol-gel, 21 electro-deposition technique 22 and spin coating. 23 While the vacuum techniques include sputtering 24 and thermal evaporation.…”
