How Solar Panels Work: In 1839 Edmond Becquerel discovered the process of using sunlight to produce an electric current in a solid material. However it was not until over a century later that the process was truly understood. Scientists learned that it is the photoelectric or photovoltaic (PV) effect which causes certain materials to convert light energy into electrical energy at the atomic level. The photoelectric effect is the physical process by which a PV cell converts sunlight into electricity. When light shines on a PV cell it may be reflected absorbed or pass right through. Only light which is absorbed generates electricity. The energy of the absorbed light is transferred to electrons in the atoms of the PV cell. With their newfound energy these electrons escape from their normal positions in the atoms of the semiconductor PV material and become part of the electrical flow or current in an electrical circuit. A special electrical property of the PV cell which we call a built-in electric field provides the force (voltage) needed to drive the current through an external load such as a light bulb.
