How does a photo diode work?|PHOTODIODE

PHOTODIODE A photo-diode is a reverse-biased silicon or germanium p-n junction in which 5.2 PHOTODIODE Reverse current of photo-diode is directly proportional to the light falling on it, which means that urrent. Keverse current is produced by thermally generated electron hole pairs re removed across the junction by the electric …
