Photodiode

Vedclass · Answer

(B) photodiode is a special type of $p-n$ junction diode that is designed to operate under reverse bias conditions.When light (photons) with energy greater than the bandgap energy of the semiconductor falls on the junction,it generates electron-hole pairs.These charge carriers are swept across the junction by the electric field in the depletion region,creating a photocurrent.Because of this property,it is used as a light detector to convert optical signals into electrical signals.
