An Investigation of Nanocrystalline and Electrochemically Grown Cu2ZnSnS4 Thin Film Using Redox Couples of Different Band Offset
Figure 6
(a) Raman spectra of CZTS film before and after test in europium nitrate solution (b) Raman spectra of CZTS film before and after test in oxalic acid aqueous solution. No significant change in Raman spectra was found after electrochemical test in formaldehyde, sodium sulfite, or sodium nitrite solution.
