Solar Cell
A solar cell, also known as a photovoltaic cell, is a device that converts sunlight directly into electricity by the photovoltaic effect. When light shines on a solar cell, it may be reflected, absorbed, or pass right through. Only the absorbed light generates electricity. The energy of the absorbed light is transferred to electrons in the atoms of a semi-conductor material. With their newfound energy, these electrons escape from their normal positions in the atoms of the semiconductor material and become part of the electrical flow, or current, in an electrical circuit. Solar cells are commonly used in aviation to power small unmanned aerial vehicles (UAVs) and to provide auxiliary power to larger aircraft.
