How does a solar cell differ from a junction diode?

A solar cell functions similarly to a junction diode but has a different construction. Instead of a typical p-n junction, a solar cell has a very thin layer of p-type semiconductor grown on a relatively thicker n-type semiconductor. Then, a few finer electrodes are applied on the top of the p-type semiconductor layer.

A solar cell is basically a p-n junction diode. Individual solar cells can be combined to form modules commonly known as solar panels.

What is the difference between a silicon diode and a solar cell?

[Sarang] was studying solar cells and realized a standard silicon diode is very similar; both are p-n junctions and the only real difference is the surface area.
