A push–pull thienoquinoidal chromophore for highly efficient p-type dye-sensitized solar cells

A push–pull thienoquinoidal chromophore, 4,4′-((4-((5-(dicyanomethylene)thiophen-2(5H)-ylidene) methyl)phenyl) azanediyl) dibenzoic acid (QT-1), was synthesized and used as a sensitizer in a p-DSC, giving a short-circuit photocurrent density of 8.2 mA cm−2 under standard AM 1.5 conditions.
