Abstract

Cyclic voltammetry (CV) measurement are used to determine the ideal potential range to deposit n-type cuprous oxide by electrodeposition method on fluorine-doped tin oxide (FTO) glass substrate using copper (II) acetate-based solution. Conventional methods of fabrication were time and cost consuming due to no ideal parameter setup. With cyclic voltammetry measurement, redox reaction could be obtained. Hence, the parameters for fabrication process were optimized. Electrodeposition method was used to deposit the cuprous oxide thin film onto the FTO glass substrate. The selected pH values for this study were pH 5.5 and 6.5 with deposition temperature of 50 and 60°C. The deposition time was fixed to 60 minutes. N-Cu2O thin films were fabricated and then characterized using Field Emission Scanning Electron Microscopy, X-Ray Diffractometer, Ultraviolet-Visible Spectroscopy and surface profiler. From the results of the analyses, the band gap obtained was 1.8 eV. The structural, morphological and optical properties showed that cuprous oxide with (111) preferred orientation were successfully fabricated.
