Abstract

The need of high transparency and high conducting electrode is largely required in modern flexible and wearable electronics. To fabricate the transparent conducting electrode copper is one of the choices. In this work, copper electrodes of various thicknesses were thermally deposited on the flexible PET substrate. Optical properties of flexible Cu electrodes were treated for various exposer times of UV-Ozone and at various temperature combinations were studied. The optical properties of the electrodes were studied by UV-visible spectroscopy. The change in UV-Ozone treatment alone as well as UV-Ozone exposure at elevated temperatures on the transparency of the Cu electrode were mainly studied. This study suggests that UV-Ozone treatment along with temperature or UV-Ozone exposure alone can be used to alter the transparency of Cu electrode coated on PET substrate. Results suggest that as the Cu film thickness reduces, the reduction in optical transmittance due to UV-O is large. Finally, the mechanism of change in the optical properties of the treated Cu electrodes were discussed. © 2024 American Institute of Physics Inc.. All rights reserved.
