In this paper, we derive the Mott-Gurney Law for space-charge-limited current and model the current density characteristics for a bilayer polymer light emitting diode (ITO/PPV/CN-PPV/Al). The organic material is assumed to be trap free and the influence of electric field on the carrier mobilities is neglected. Since the hole energy barrier between the ITO and PPV is less than 0.60 eV, the bottleneck for current flow is bulk-limited, resulting in space-charge-limited current. We discuss future plans for interposing a thin-layer of metal (Au, Pt, Pd, or AuPd) between the ITO and PPV. Experimental data will be compared to the J-V curve produced in this model, providing insight on how the metal buffer influences the range of potentials for which the current is space-charge-limited. Finally, the emissive spectrum is modeled with consideration of phonon-exciton coupling.
