Investigation of Morphological and Optical Properties of Electrodeposited Cuprous Oxide (Cu₂O) Thin Film Modified with Copper(II) Phthalocyanine-Tetrasulfonic Acid Tetrasodium Salt

Abstract:

Metal oxides are widely used as components in photovoltaic cells such as transparent conducting front electrodes or electron-transport layers, while only few metal oxides have been used as light absorbers. In this study, cuprous oxide was modified by anchoring TSCuPc dye molecules via potentiostatic electrodeposition approach. Fourier Transform Infrared Spectroscopy results display the different vibration peaks for S=O bond and C-N present in the TSCuPc modified Cu₂O deposits signifying the attachment of TSCuPc on Cu₂O. The highest absorbance peaks of Cu₂O and TSCuPc at approximately 420 nm and 650 nm respectively was observed when 20uM of TSCuPc was added in the electrodeposition solution. Scanning Electron Microscopy reveals the formation of Cu₂O film and formation of secondary submicron size structures with the addition of TSCuPc. The surface morphology of the secondary structures changes as the concentration TSCuPc increases. With the aforementioned results, it was verified that TSCuPc can be anchored to Cu₂O via electrochemical route which could pave way in developing materials with high absorption in visible light applicable for optoelectronic devices.
