(Invited) Role of the Metal-Organic Interfaces in the Dark Current-Voltage Characteristics of Organic Solar Cells

Abstract.  We present a model for the current-voltage curves of organic solar cells (OSCs), operating at dark conditions. The model relates the free charge density at the contact interface with the current density in OSCs. The strength and novelty of the model lie in the use of appropriate and physically-based boundary conditions for the charge and potential at the metal-organic interfaces. These boundary conditions contain …
