- A photodiode is a PN-junction diode that consumes light energy to produce an electric current. They are also called a photodetector, light detectors, and photo sensors.
- Photodiodes are designed to work in reverse bias conditions. Typical photodiode materials are Silicon, Germanium, and Indium gallium arsenide.
Symbol of Photodiode:
Applications of Photodiode:
- Photodiodes are used in solar cell panels.
- Photodiodes are used in logic circuits.
- Photodiodes are used in the detection circuits.
- Photodiodes are used in character recognition circuits.
- Photodiodes are used for the exact measurement of the intensity of light in science and industry.
- Photodiodes are faster and more complex than normal PN junction diodes and hence are frequently used for lighting regulation and optical communication.
