Dielectric constant enhancement of non-fullerene acceptors via side-chain modification.

Chemical communications (Cambridge, England)

Donaghey JE, Armin A, Burn PL, Meredith P.
PMID: 26255993
Chem Commun (Camb). 2015 Sep 25;51(74):14115-8. doi: 10.1039/c5cc05853h.

The low dielectric constants of conventional organic semiconductors leads to poor charge carrier photogeneration in homojunction organic solar cells due to large exciton binding energies. Increasing the dielectric constant can potentially enhance the spontaneous exciton dissociation rate at room...
