Influence of a strong electromagnetic field on currents and electromotive force in the $p-n$-junctions

The influence of a strong electromagnetic field on the currents and electromotive forces in the $p-n$-junction is considered. It is shown that under the influence of an electromagnetic wave the $p-n$-junction becomes a source of electromotive force (EMF) dependent on the current. Obtained, analytical expression for EMF and internal resistance of such source. From the experimental graphs of the current-voltage characteristic of the $p-n$-junction placed in a strong microwave (microwave) electromagnetic field, plots of the dependence of the EMF and internal resistance on currents through a diode are obtained.
