Advantages and Disadvantages of Photodetector
Given Below are Advantages and Disadvantages of PhotoDetector :
Advantages
- They are cost-effective, require less space and are light in weight.
- Less noise is generated in the output.
- They have high charged carriers(photons) detection efficiency and operational speed.
- They have a long duration of lifespan.
- Quantum efficiency is high.
Disadvantages
- They have a small limit of internal gain (almost negligible).
- The response time is very slow.
- The depletion region where the electric field is present is small.
- It requires an external voltage source.
- Output photocurrent is less.
Photodetector
A photo is nothing but light. A detector is nothing but a device that detects something. Therefore, we can directly conclude that a photodetector can be defined as a device that is used to detect light radiations by absorption.
