Definition of "Cell Barrier" |
A very thin region of static electric charge along the interface of the positive and negative layers in a photovoltaic cell. 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. Also called depletion zone, cell junction, or space charge. / A very thin region of static electric charge along the interface of the positive and negative layers in a photovoltaic cell.
