Explains the photoelectric effect
WebWhat is Photovoltaics? Photovoltaics is the direct conversion of light into electricity at the atomic level. Some materials exhibit a property known as the photoelectric effect that causes them to absorb photons of light and release electrons. When these free electrons are captured, an electric current results that can be used as electricity ... WebMar 20, 2015 · 7. The photoelectric effect occurs when an atom (or ion) absorbs the energy of a photon and an electron is emitted. Some of the photon energy is used to liberate the electron, the rest goes into the electron kinetic energy. The same thing cannot happen when light interacts with a free electron (e.g. see Free electron can't absorb a photon ).
