Electrical and photoelectrochemical characteristics of flexible CdS nanocomposite/conducting polymer heterojunction

The electrical properties of CdS-polyvinyl alcohol (CdS-PVA) nanocomposites have been investigated in details. The junction behavior of CdS-PVA and a conducting polymer poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) heterojunction have been studied. The current-voltage characteristics of the nanocomposite samples have also performed at different bending angles. The bending study has been carried out after deposition of CdS-PVA and CdS-PVA/PEDOT:PSS heterojunction films on indium tin oxide coated (ITO) flexible polyethylene terephthalate (PET) substrates. Spectral dependent photoconductive properties of the nanocomposite-polymer heterojunctions have been investigated. The electrochemical photosensing behaviors have been demonstrated using CdS-PVA nanocomposites and CdS-PVA/PEDOT:PSS heterojunction films as photoanodes.
