First-Principles Study on Influences of Crystal Structure and Orientation on Band Offsets at the CdS/Cu2ZnSnS4 Interface

International Journal of Photoenergy, 2012
Cu2ZnSnS4 (CZTS) has attracted much attention recently as an absorber layer material in a heterojunction solar cell. Using the first-principles method, we calculate the band offsets for the CdS/CZTS heterojunction.

One-step CZT electroplating from alkaline solution on flexible Mo foil for CZTS absorber [PDF]

Journal of Solid State Electrochemistry, 2021
AbstractIn this work, Cu-Zn-Sn (CZT) is co-electrodeposited onto a flexible Mo substrate exploiting an alkaline bath (pH 10). The plating solution is studied by cyclic voltammetry, highlighting the effects of potassium pyrophosphate (K4P2O7) and EDTA-Na2 on the electrochemical behavior and stability of the metallic ionic species.
