Photocurrent
From Wikipedia, the free encyclopedia
Photocurrent is the current that flows 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).
