    depends on the semi conductor property of silicon. The silicon is a unique substance that has revolutionized the way electronic appliances work. This property is used to generate electricity from the solar panels. In order to understand how solar panels work we need to understand how silicon works at an atomic level. Silicon in its pure form i.e. when all the impurities have been removed a silicon atom is bonded with another silicon atom. Since the valency of silicon atom is 8 which means that there are

    A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical
