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.

Nonfullerene electron acceptor materials have gained enormous attention due to their potential as replacements of fullerene electron acceptors in bulk heterojunction organic solar cells. A novel thiophene bridged selenophene-containing perylene diimide acceptor PDISe-T has been synthesized and applied as an acceptor in nonfullerene organic photovoltaic cells. The inverted organic photovoltaic (OPV) solar cells based on PDISe-T:PBT7-Th (acceptor:donor) blends give a power conversion efficiency (PCE) value of 2.53% with an open-circuit voltage ([Formula: see text] of 0.92[Formula: see text]V, a [Formula: see text] of 6.55[Formula: see text]mA[Formula: see text]cm[Formula: see text], and a fill factor (FF) of 0.42.
