he solar cell are two layers of silicone (a semiconduc r). One layer is negatively charged and full of electro charged and lacking in electrons. How electricity is madeWhen sun ght strikes a PV cell, some the energy is absorbed. This energy ‘excites’ the electrons in t e negative layer and gives them enough energy to move.The elec
They are constructed of layers of n-type and p-type semiconductors that form a p-n junction. When sunlight is absorbed, electrons are released and produce an external DC current. There are three main types of solar cells: monocrystalline, polycrystalline, and amorphous, with monocrystalline being the most efficient.
