Abstract
The kinetics of photogeneration of electric charge carriers in organic molecular semiconductors in strong electric fields is investigated within a theoretical model that includes the diffusion-drift mechanism of motion of electric charge carriers. In the framework of the proposed model, it is established that the time dependence of the probability of dissociation of a geminal pair exhibits an exponential behavior. The time constant strongly depends on the electric charge carrier hopping distance and the external electric field strength in accordance with the experimental data.
