p-n junction
The junction at the interface between two differently doped
layers of semiconductor material
– one layer doped with a positive-type dopant
(see p-type semiconductor),
the other layer with a negative-type dopant (see n-type
semiconductor). An electrical field is established at the p-n junction,
which gives direction to the flow of heat- or light-stimulated electrons.
See also solar cell.
