Introduction to Photodiode LED

Photodiode LED, also known as photoelectric LED, is a device that combines the functionalities of a photodiode and an LED. It can both emit light and detect light, making it highly efficient in various optoelectronic applications. The core of the Photodiode LED is a semiconductor material, typically made of gallium arsenide (GaAs), gallium nitride (GaN), or indium gallium nitride (InGaN). These materials allow the Photodiode LED to operate in both photovoltaic mode (light detection) and photoelectric mode (light emission).

Working Principle of Photodiode LED

The working principle of the Photodiode LED is based on the photoelectric effect, which occurs when light is absorbed by a semiconductor material. When light hits the semiconductor, electrons are excited from the valence band to the conduction band, generating a flow of electric current. In photovoltaic mode, the Photodiode LED converts light energy into electrical energy. In photoelectric mode, the device emits light when an electric current is applied to it.
