A planar dithiafulvene based sensitizer forming J-aggregates on TiO2 photoanode to enhance the performance of dye-sensitized solar cells

The self-assembled J-aggregates of a newly synthesized planar dithiafulvene sensitizer optimized the TiO2/dye interface, uplifting the power conversion efficiency from 4.68% to 7.48% alongside with a high open-circuit voltage of above 850 mV.
