In a Photodiode the Current Is Due to?

The current is generated when photons are absorbed in the photodiode. Photodiodes may contain optical filters, built-in lenses, and may have large or small surface areas. Photodiodes usually have a slower response time as their surface area increases.

When photodiode conducts the current is called?

The photodiode generates current when exposed to light. It can also be called a photodetector or photosensor. It works on the principle of the photoelectric effect. Photodiodes work in reverse biased mode. When the junction of the photodiode is illuminated, then the electric current starts flowing.

Which way does current flow through a photodiode?

Current passing through the photodiode can only flow in one direction based on the P and N doped materials. If reverse biased, current will not flow through a photodiode without incident light creating photocurrent.
