Current–voltage characteristics of a PEDOT:PSS/PFO (80 nm)/MoO3 hole-only MIM diode. PEDOT:PSS is grounded. The solid lines are fits to the experimental data (symbols) using the analytical equation for the diffusion-limited current. The deviation at higher voltages is due to the current being dominated by the drift term (space-charge-limited current, Equation (1)) above the built-in voltage. The dashed lines represent numerical device calculations using a drift-diffusion solver7 with exactly the same parameters as extracted from the analytical description.
