Abstract
Two pulse femtosecond photocurrent experiments are performed on a conjugate d polymer photodiode. With a photon energy of 3.1eV a first laser pulse exc ites singlet excitons. Photons absorbed from a time-delayed second pulse wi th a photon energy of 1.26eV lead to the excitation of higher lying states. The high dissociation rate for these states leads to an efficient two step carrier generation.
