摘要: Novel nanoflakes of Cu2ZnSnS4 (CZTS) thin film were directly deposited on fluorine doped tin oxide (FTO)-coated glass substrates by the successive ionic layer adsorption and reaction (SILAR) method. The results energy dispersive X-ray spectroscopy (EDX) indicate that these CZTS films are Cu rich S poor. combination diffraction (XRD) Fourier Transform-Raman (FT-Raman) reveal exhibit a strong preferential orientation flakes along [1 1 2] direction small Cu2−xS phase exists in films. Photoelectrochemical characterization revealed p-type photo-response when illuminated an aqueous Eu3+ redox electrolyte. total conversion power cell is 1.85% under 30 mW/cm2 illumination.
