Onsager-Braun models

Photocurrent generation, involving the CT state, has often been treated [106, 107, 143-145] according to the Onsager-Braun model [146, 147], to describe the field dependence for charge separation and charge recombination from the CT state. The...

A well-established model to describe free charge generation in isotropic media via split-up of Coulombically bound geminate pairs is the Braun-Onsager theory [164] (see also [165] for a detailed discussimi on the accuracy of the model). Carriers are...
