Abstract

The effect of exciplex dynamics on the device characteristics of organic semiconductor bilayer structures is explored. Exciplex formation, dissociation, and relaxation to the ground state are incorporated into a physics-based device model. The model is applied to both organic light emitting diodes and photovoltaic cells. In the examples, C 60and tetracene parameters are used for the electron and hole transport layers, respectively.
