There are no extra electrons and no holes because the extra electrons from the n-type part of this region have fallen down into the holes, thereby filling the holes.

AI Customer ServiceNear the junction, the N-type material electrons diffuse across the junction, combining with holes in P-type material. The region of the P-type material near the junction takes on a net negative charge because of the electrons attracted. Since electrons departed the N-type region, it takes on a localized positive charge.
These electrons diffuse toward the junction. The positive terminal removes electrons from the P-type semiconductor, creating holes that diffuse toward the junction. If the battery voltage is great enough to overcome the junction potential (0.6V in Si), the N-type electrons and P-holes combine annihilating each other.
The negative terminal attracts P-type majority carriers, holes, away from the junction. This increases the thickness of the nonconducting depletion region. There is no recombination of majority carriers; thus, no conduction. This arrangement of battery polarity is called reverse bias.
As a result, there are no free charged particles (neither electrons nor holes) which can move in response to an electric field. Therefore, the region around the junction between p-type and n-type material is an insulator. A seamless join of p-type and n-type material is known as a semiconductor diode.
If this happens in the n-doped side of the p-n junction, the newly excited electron is driven away from the junction, and the hole is swept across the junction to the p-doped side. This separation of the electron-hole pair is achieved by the action of the electric field in the space charge region.
Also, the negative wire from the battery injects electrons into the p-type material, filling in more of the holes and extending the width of the negative charge layer, while the positive terminal from the battery sucks negative electrons out of the n-type region, extending the width of the positive charge layer.
