How solar panels work (PN junctions)

Bring in the sun. As rays of sun (called photons) enter the p-n junction (especially in the depletion zone), the solar energy (which we normally feel as heat) is absorbed. This gives some of the electrons enough energy to "break free", and creates a new electron-hole pair – that is, a free electron, and an electrically-charged space where ...
