Ultrafast Charge Separation in Low Band-Gap Polymer Blend for Photovoltaics
We track ultrafast charge dissociation in a particularly promising low-band-gap- polymer:fullerene blend for organic photovoltaics. Impulsive photoexcitation with excess energy leads to a 30-fs formation of an hot charge transfer state, precursor of free carriers.
