Performance Enhancement by Blending an Electron Acceptor in TiO2/polyphenylenevinylene/Au Solid-state Solar Cells

When an electron acceptor, [2-[2-[4-(dimethylamino)phenyl]ethenyl]-6-methyl-4H-pyran-4-ylidene]propanedinitrile (DCM) was blended into poly[2-methoxy-5-(2ʹ-ethylenehexyloxy)-1,4-phenylenevinylene] (MEH-PPV) in a TiO2/MEH-PPV/Au sandwich-type solar cell, the cell performance was remarkably enhanced, resulting in 0.47% of energy conversion yield under the irradiation of AM 1.5–100 mW/cm^2.
