Solar cell. Solar, or photovoltaic, cells convert light into electrical energy. The cell is made from a semiconductor. When light hits the semiconductor it releases electrons that are picked up by a grid of wires and form an electrical current. Many cells may be grouped together to form a solar panel. Solar power is an environmentally friendly energy source.
