Molecular engineering of panchromatic isoindigo sensitizers for dye-sensitized solar cell applications.

A panchromatic dye was synthesized with an isoindigo core as a linker to bridge with a bis(4-tert-butylphenyl)phenylamine donor and a cyanoacetic acid acceptor for dye-sensitized solar cells, showing a broad spectral response and a high conversion efficiency of 7.55% under AM 1.5 conditions.
