How Solar Cells Work

This diagram shows what happens inside a solar panel when light hits it. The photons from a  light source are able to stimulate the electrons in the solar panel. The negatively charged electrons get absorbed into the silicon semiconductor.  When one electron is pulled out of an atom, it creates what is


called a hole. Once one hole is formed, it creates an opportunity for another electron to leave its own atom and travel to the next atom with a hole, until it makes its way to the silicon. Because of the special composition of the silicon solar cells, once the electrons pass through it, they can’t pass back. This flow of electrons creates an electric current.
