Interface Characteristics

ABSTRACTA non-aqueous Poly(3,4-ethylenedioxythiophene): poly(styrenesulfonic acid) (PEDOT:PSS) dispersion was developed to enable the accommodation of non-polar additives. This additional functionalisation targets selected interface characteristics and results in an improved adhesion of PEDOT:PSS on the photo-active layer. Such mechanical robustness is paramount in inverted organic photovoltaic cells contributing to improved long-term stability.

The present manuscript is dedicated to In free transparent conductive andflexible heterostructure electrodes. The new electrodes correspond todielectric/metal/dielectic (D/M/D) multilayer structures deposited under vacuum. In thepresent work, after a fast review of the general properties of D/M/D electrodes using Ag asmetal, we then develop the study of D/Cu/D multilayer structures. We propose to substituteCu to Ag, because it is far cheaper. However, Cu having tendency to diffuse into manydielectrics it is difficult to obtain stable electrodes. We show that using Cu:alloys, i.e. Cu:Niand Cu:Al, as metal it is possible to decrease significantly the Cu ions diffusion and toincrease significantly the stability of the multilayer electrodes with Cu. Finally, we show thatwhen these electrodes are used as anode in organic photovoltaic cells, they can allowachieving efficiency similar to that obtained with ITO.
