Summary Of “How Do Photovoltaics Work” Photovoltaics is a term referring to the direct conversion of light into electricity at the atomic level as explained in How do Photovoltaics Work. The way that photovoltaics work is through the property known as the ‘photoelectric effect’ that causes some materials to absorb photons of light and release electrons that are captured, forming an electric current. “The photoelectric effect was first noted by a French physicist, Edmund Bequerel, in 1839” he found that specific materials would produce electric currents when in exposure to light, such as the light radiated from the sun, Sol (Knier 1). “In 1905, Albert Einstein described the nature of light and the photoelectric

The ‘Photoelectric effect’ was discovered by a French physicist named Edmund Bequerel in 1839. He found that certain materials produce energy in exposure of light, such as the one from the sun. Such researchers have inspired the first PV cell which uses a thin semiconductor wafer which is specially treated to create an electric field with polar sides. These cells work by having electrical conductors on each polar side of the field which gain energy when light hits the material, because electrons get knocked loose and they can be stored as electricity. As you add more PV cells, the amount of energy increases, not necessarily just because there’s more, the name for this organization is called a module. Many modules put together is called an Array, which also produces a lot of energy. The current highest efficiency has been about 35% under concentrated sunlight. These arrays/modules can be used in space to power space stations/shuttles, one example would be the I.S.S. (International Space Station) which uses PV arrays/modules to gain energy from the sun, with an efficiency of 14%. The energy coming from the sun has an intensity of 4 x 10 to the power of 23, aka twenty three zeroes after four. It is currently uncertain where the solar energy is no longer viable from the
