Abstract
A new evaporable electron acceptor material for organic photovoltaics based on N-ethyl barbituric acid bithiophene (EBB) has been demonstrated. Bilayer devices fabricated with this non-fullerene acceptor and boron subphthalocyanine chloride (SubPc) donor produce power conversion efficiencies as high as 2.6% with an extremely large open-circuit voltage approaching 1.4 V.

Small molecule n-type materials were designed for solution processing, based on polyaromatic hydrocarbon diimides, diketopyrrolopyrrole, benzothiazdiazole, and oligothiophene derivatives functionalised with acceptor moieties,[2,5] and have achieved efficiencies over 2% as drop in replacements for 6,6-phenyl-C61-butyric acid methyl esters (PCBM) with the prototypical donor material poly-3-hexylthiophene (P3HT)
