Figure 9: Homogeneity of photocurrent actuation throughout an OEH device’s surface. (a) Current in 16 1.25 mm × 1.25 mm areas covering the entire surface of an OEH device at various voltages. The areas were lighted one at a time. (b) Standard deviation of current values throughout the 16 areas: functional dependence on voltage.
