Circuit of photodiode

Webphotodiode is the bandgap energy E g of its active region. The photogenerated electrons and holes in the depletion layer are subject to the local electric field within that layer. The electron/hole carriers drift in opposite directions. This transport process induces an electric current in the external circuit. WebFeb 20, 2024 · The photodiode is a special type of diode which operates in reverse bias conditions. When the incident light on the photodiode increases, the reverse current in a photo-diode also increases. Diode current flows from n to p. Net current flowing is due to only minority charge carriers.
