We explore theoretically the effect of incorporating a thin tunnel barrier between the electron and hole transport layers of organic heterojunction photovoltaic devices. Macroscopic device characteristics (such as short-circuit current, open-circuit voltage, and power efficiency) are related to microscopic processes (such as exciton diffusion, dissociation, and recombination). We show that a tunnel barrier that alters the rates of different transfer processes at the interface between the electron and hole transport layers can significantly affect the efficiency of organic photovoltaic devices.
