•Extraction of built-in voltage from the steady-state current–voltage characteristics of a diode is described.•Proposed method relies on current–voltage characteristics being exponential below built-in voltage and power-law above it.•A sharply defined peak at a voltage proportional to built-in voltage is created.•Proposed technique is less sensitive to presence of traps.
A technique for extraction of built-in voltage from the steady-state current–voltage characteristics of a two terminal organic diode is described which does not require assumption of quadratic dependence of current on voltage. The technique relies instead on current voltage characteristics being exponential below built-in voltage and power-law above it to generate a sharply defined peak at a voltage proportional to built-in voltage. Simulation results are used to validate the proposed method and experimental results obtained with P3HT and P3HT:PCBM blends are presented.
