Organic semiconductors, metal oxides, and nanomaterials hold promise as the future basis for efficient, cost-effective, large scale optoelectronic devices. This tool computes the transient and steady-state charge and exciton distributions in devices composed of a sequence of planar, distinct layers of semiconductor and nanostructured materials.

The model utilizes a rate equation formalism based upon the idea of hopping across a one-dimensional chain of atoms and molecules. In the limit of low field and a narrow, the model is equivalent to the drift-diffusion equations. The advantage of the rate equation formalism lies in its generalizability; various injection models, Foerster resonant energy transfer, interfacial recombination, and tunneling can be studied within this framework.
