Introduction to Photodiode LED

Photodiode LED, also known as a photoelectric LED, is a semiconductor device that combines the functions of a photodiode and an LED. A photodiode is a device that converts light into an electrical current, while an LED emits light when an electric current passes through it. By integrating these two functionalities into a single device, Photodiode LED offers a versatile solution for various applications.

How Photodiode LED Works

The working principle of a Photodiode LED is based on the photoelectric effect, where photons with sufficient energy are absorbed by the semiconductor material, causing electrons to be released and generating an electrical current. The device typically consists of a p-n junction, where the p-type material is doped with acceptor atoms and the n-type material with donor atoms. When light is incident on the device, the photons are absorbed by the semiconductor material, creating electron-hole pairs. These pairs are then separated by the electric field within the p-n junction, resulting in a flow of electrical current.
