Solar Cell Turns Photons into Electrons

Photovoltaic cells turn the photons from sunlight into electrons producing a current flow, thus photovoltaic PV cells are powered by incident sunlight and so are commonly called solar cells. Solar cells are made using silicon based semiconductor materials with different electrical properties. An n-type semiconductor material with excess negatively charged electrons is fused together with a p-type semiconductor which has an excess of positively charged holes to create a p-n junction. When a photon of light hits this p-n junction, electrons are release to form an electrical current
