PV cells are typically made of two layers of semiconductor materials. The first layer, known as the N-type semiconductor, has an excess of free electrons. The second layer, the P-type...

The current (and power) output of a PV cell depends on its efficiency and size (surface area), and is proportional to the intensity of sunlight striking the surface of the cell.
