Recombination Dynamics

Ultrafast hole injection from photoexcited diketopyrrolopyrrole-based dyes into mesoporous NiO films was followed by charge recombination that spanned time scales from pico- to microseconds, which was reflected in large variations in dye regeneration and device solar energy conversion efficiencies.
