Solar panels (photovoltaic panels) converts sunlight into electrical energy in the energy. When sunlight falls on the solar panel is made up of energy producing cells. This process is a specific substance found in almost all the solar cell is based on: the electrical properties of semiconductor silicon Bio. 

Silicon is the most abundant element on earth after oxygen because it is quite cheap and virtually infinite natural resources. However, to use these materials for photovoltaic multi-stage, complex operations must be done. Natural silica sand is converted into pure crystalline silicon. Depending on the structure and production methods most commonly used solar panels:
