Presentation Summary

  • A gold thin film of only 0.5 nm introduced at the interface between the ITO or ZnO anode and the organic electron donor in organic photovoltaic cells induces a strong improvement of the cell efficiency.
  • XPS and SEM have shown that only 15% of the anode is covered by gold, which proves the high efficiency of gold as anode buffer layer in organic photovoltaic devices.
  • The average gold nano-dots size is 5-6 nm2, while the averaged distance between them is 5-6 nm.
  • These gold nano-dots are also efficient in others organic devices such as organic light emitting diodes.
