Photocurrent-potential curves
Web(a) Photocurrent-potential (J–V) curves and (b) Transient photocurrent measurement for PEC water oxidation reaction with pristine and doped α –Fe 2 O 3 photoanodes under … Photocurrent is the electric current through a photosensitive device, such as a photodiode, as the result of exposure to radiant power. The photocurrent may occur as a result of the photoelectric, photoemissive, or photovoltaic effect. The photocurrent may be enhanced by internal gain caused by interaction among ions and photons under the influence of applied fields, such as occurs in an avalanche photodiode (APD).
