When all the holes are filled with electrons in the depletion zone, the p-type side of the depletion zone (where holes were initially present) now contains negatively charged ions, and the n-type side of the depletion zone (where electrons were present) now contains positively charged ions. This creates an area around the junction, called the depletion zone, in which the electrons fill the holes (Fig. Near the junction of the two layers, the electrons on one side of the junction (n-type layer) move into the holes on the other side of the junction (p-type layer). In the n-type layer, there is an excess of electrons, and in the p-type layer, there is an excess of positively charged holes (which are vacancies due to the lack of valence electrons).

Instead, it is free to move inside the silicon structure.Ī solar cell consists of a layer of p-type silicon placed next to a layer of n-type silicon (Fig. It bonds with its silicon neighbor atoms, but one electron is not involved in bonding. Phosphorus has five electrons in its outer energy level, not four.

The n-type silicon is made by including atoms that have one more electron in their outer level than does silicon, such as phosphorus. Because boron has one less electron than is required to form the bonds with the surrounding silicon atoms, an electron vacancy or “hole” is created.

The p-type silicon is produced by adding atoms-such as boron or gallium-that have one less electron in their outer energy level than does silicon. A solar cell is made of two types of semiconductors, called p-type and n-type silicon.
