Solar panel industry. Worker assembling pieces of polycrystalline silicon to form photovoltaic cells. Here,the polycrystalline silicon has been laminated by a backing material,and several of the photovoltaic cells (squares) have been joined together to form a larger array (rectangle). The entire array plus the supporting casing seen around the edge,is known as a solar panel. Silicon is used in photovoltaic cells because,as a semiconductor material,it has space in its electronic structure to absorb the energy of incoming sunlight and convert it into an electrical current.
