Description:
Cu/Zn disorder in the kesterite Cu2ZnSnS4derivatives used for thin film based solar cells is an important issue for photovoltaic performances. Unfortunately, Cu and Zn cannot be distinguished by conventional laboratory X-ray diffraction. This paper reports on a resonant diffraction investigation of a Cu2ZnSnS4single crystal from a quenched powdered sample. The full disorder of Cu and Zn in thez= 1/4 atomic plane is shown. The structure, namely disordered kesterite, is then described in the I ar 42m space group.
