Amide-linked hole transporting material for solid-state dye-sensitised solar cells

This data represents the first use of an amide-based hole transport material in a solid-state dye-sensitised solar cell. A substantial improvement in solar cell efficiency from 0.04 to 2.26% was achieved through prolonged oxidation in air and light soaking for the amide-based hole-transporting mediator, TPABT. Time-resolved spectroscopic studies show that the oxidation state and additive concentration alter the charge-transfer and regeneration kinetics, which are consistent with the time-dependent changes in device properties.
