What Is Photodiode? Working, V-I Characteristics, Applications
See more on electronicshub.orgGenerally, when a light is made to illuminate the PN junction, covalent bonds are ionized. This generates hole and electron pairs. Photocurrents are produced due to generation of electron-hole pairs. Electron hole pairs are formed when photons of energy more than 1.1eV hits the diode. When the photon enters the depletion regi…- Reviews: 4
