Abstract

In this paper, electrodeposition and visible light photocurrent responses of Zn-doped Cu2O were reported. The electrodeposition process was conducted with different deposition time to study the growth of the Cu2O deposit. The structural investigation and elemental analysis were performed on an energy dispersive X-ray spectrometer and X-ray diffractometer, respectively. The growth of Cu2O crystal was studied from the micrograph obtained using a field emission scanning electron microscope. The photoelectrochemical measurements conducted using linear sweep voltammetry technique show that the onset of initial current photocurrent shifted to a lower voltage and the photocurrent of the deposit rises with the increase of the Cu2O deposition time. This study shows the effect of electrodeposition time on the crystal growth and photocurrent response of the Cu2O.
