Detailed Solution
Download Solution PDFIn a Photodiode, carriers are generated in the depletion region because the width of the depletion region increased when the photodiode operates in reverse biased.
So option (2) is correct.
The basic working model of photo-diode is as shown:
Here,
e- = electrons
O = holes
⊕ = positive ions
⊖ = negative ions
- Carriers are generated in the depletion region mainly due to the incident photons on the surface of semiconductor material.
- A photodiode is used to convert light signals into electrical signals.
- In photodiode, the current called photo-current is proportional to the intensity of the light incident on the surface.
