PV cell itself is nearly 100% silicon, and silicon is the second most common element in the Earth''s crust. The silicon for PV cells is obtained by high-temperature processing of quartz sand (SiO 2) that removes its oxygen molecules. The refined silicon is converted to a PV cell by adding extremely small amounts of
2. Health and Safety Concerns of Photovoltaic Solar Panels Materials used in photovoltaics solar panels The basic building block of a photovoltaic solar system is the solar cell. Solar cells are solid state, semiconductor devices that convert sunlight into electricity. Typically a number of individual cells are connected together to form modules, or solar panels. …
