Working Principle of Photodiode 5mm

Photodiode 5mm is a semiconductor device that utilizes the photoelectric effect. When the photodiode is exposed to light, the photons with energy greater than the bandgap of the semiconductor material will excite electrons to the conduction band, thus generating an electrical current.
