Paper Abstract

We present a microscopic theory of charge transport in conjugated polymers based on polaron drift along polymer segment and on polaron hopping between segments. We show that this model is able to reproduce the current-voltage characteristics of 'good' hole-only devices based on PPV in the whole range of fields. We also present a microscopic theory of electrode injection into conjugated polymers. We show that this model is able to reproduce the current voltage characteristics of contact limited devices based on PPV.
