| Abstract |
| Ultraviolet ozone (UVO) surface-treatment was carried out on fluorine-doped tin oxide (FTO) substrate prior to the growth of Cu2O thin-films by electrochemical deposition. This was done to improve their photo-electrochemical properties. We examined the effect of various durations of UVO surface-treatment on the morphological, structural, optical and photo-electrochemical properties of Cu2O thin-films. The effects were measured via field-emission scanning-electron microscopy (FE-SEM), X-ray diffraction (XRD), UV-visible spectroscopy and 3-electrode potentiostat, respectively. The highest photocurrent density (4.22 mA/cm2) was achieved with a 2-minute UVO surface-treatment.(Received August 19, 2014) |
