Optical excitation of a polymer‐fullerene solar cell via the charge‐transfer transition at the donor‐acceptor interface, leads to generation of charge carriers displaying dynamics that are indistinguishable from those generated by excitation of the conjugated polymer at higher photon energy. This indicates that excess energy liberated in the photoinduced electron transfer between polymer and fullerene is not essential for the charge carrier generation.
