Figure 7. SCL characteristics for Ag-normal OSCs measured at room temperature (T = 300 K).

Left graphs are photocurrents versus effective applied voltage (V₀-V) at different incident light intensities. (a) Ag-planar-normal device, and (c) Ag-grating-normal device. The black solid lines in (a) and (c) represent the square-root dependence of photocurrent on effective applied voltage (SCL region). Right graphs are photocurrents versus incident light intensity at different effective applied voltages. (b) Ag-planar-normal device, and (d) Ag-grating-normal device.
