Abstract :
This paper introduces a generalized charge transport model for hybrid organic-inorganic semiconducting systems. The model is formed of five coupled nonlinear partial differential equations consisting of the Poisson´s equation and four continuity equations for electrons, holes, excitons, and triplets. The model allows transformation of one particle (electron/hole, excitons, and triplets) to another through a transformation ratio. Variables are electric potential, density of electrons, holes, excitons and triplets. Furthermore, the model is capable of modeling heterointerfaces, density of interfaces traps, dissociation of excitons at the heterointerfaces, and recombination velocities for different particles at the metallic contacts.
