Explain the working of a photodiode.

A p-n photodiode is fabricated from a semiconductor with a band-gap of $2.8 \mathrm{eV}$. It can detect a wavelength of $6000 \mathrm{nm}$.

In the following a statement of Assertion is followed by a statement of Reason.

Assertion: Photodiode should be used in reverse bias.

Reason: It is easier to observe the change in the current in photodiode circuit with change in the light intensity if photodiode is used in reverse bias.
