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.
