Photovoltaic (PV) Cells: How They Power Our Future

The Photovoltaic Effect Explained: The photovoltaic effect occurs when photons, which are particles of light, strike a semiconductor material (usually silicon) in a PV cell and transfer their energy to electrons, the negatively charged particles within the atom. This energy boost allows electrons to break free from their atomic bonds.

From sunlight to electricity

Most photovoltaic cells are made of silicon, an element that is at the heart of all modern electronics. Silicon is special because of the arrangement of its electrons—it has four out of the possible eight electrons in its outermost shell. This means that it makes perfect covalent bonds with four other silicon atoms, forming a lattice structure.

How a Solar Cell Works

A solar cell is made of two types of semiconductors, called p-type and n-type silicon. 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. 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.
