DEF

A very thin region of static electric charge along the interface of the positive and negative layers in a photovoltaic cell.

OBS

The barrier inhibits the movement of electrons from one layer to the other, so that higher energy electrons from one side diffuse preferentially through it in one direction, creating a current, and thus a voltage across the cell.
