Abstract

The intrinsic charge carrier photogeneration in polymers is depicted as a multistage process which can be described within the frame of the ballistic model. Thermalization of the autoionized excited state proceeds in an isotropic quasi-continuum and therefore an initial distribution of radii of charge transfer states can be assumed. The dissociation of electron-hole pairs is in a good agreement with predictions based on the Onsager theory of geminate recombination. The pair separation distances, typically 2 to 3 nm, were observed in several polymers.
