Photovoltaic cell production worker examining photovoltaic cells. Each rectangle consists of a layer of polycrystalline silicon,with a laminated backing and printed circuitry to conduct the electricity formed when sunlight falls on the silicon. 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.
