Terminal voltages of PN junctions form certain barrier potentials, and when the forward bias voltage is added, the barrier potential decreases and most charge carriers in P area and N area diffuse to each other. As the electron mobility is much higher than the holes mobility, large amount of electrons diffuse to P area, causing charge carriers entering P area. These electrons combine with the holes on the valence band with energy emission in the form of light."
