Supramolecular organic–inorganic domains integrating fullerene-based acceptors with polyoxometalate-bis-pyrene tweezers for organic photovoltaic applications

Polyoxometalate-bis-pyrene receptors for phenyl-C61-butyric acid methyl ester (PCBM) provide an interfacial layer (IFL) material enhancing the open circuit voltage of the organic photovoltaic device of about 34% under applied bias of ±5 V.
