Source sentences:
text: As the name implies, electrons in the conduction band are free to move about the silicon.
text: The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into the electric field generated by the solar cells which then pull these free electrons into a directional current.
text: Electrons are then freed from their host atom, and they move freely as electricity.
text: These electrons, called free carriers, then wander randomly around the crystalline lattice looking for another hole to fall into and carrying an electrical current.
text: In their excited state in the conduction band, these electrons are free to move through the material, and it is this motion of the electron that creates an electric current in the cell.
text: Electrons on the low side of the bandgap are trapped in place, while electrons that get an energy boost to the high side of the bandgap are free to move -- including being free to move out of the semiconductor altogether and make themselves useful in electrical circuits.
text: Once the electron is free, the electric field pulls it towards the P-side and the hole is pulled towards the N-side.
