    Photoelectric Effect

    The frequency of red light (left) is less than the threshold frequency of this metal ( � red < � 0 ) (ν red ​ <ν 0 ​ )left parenthesis, \nu, start subscript, start text, r, e, d, end text, end subscript, is less than, \nu, start subscript, 0, end subscript, right parenthesis, so no electrons are ejected. The green (middle) and blue light (right) have � > � 0 ν>ν 0 ​ \nu, is greater than, \nu, start subscript, 0, end subscript, so both cause photoemission. The higher energy blue light ejects electrons with higher kinetic energy compared to the green light.

    Light holds many of the keys to the cosmos. Neil deGrasse Tyson explores light and enlightenment, from William Herschel's chance discovery of infrared to the beginning of astrophysics.

    Work by Isaac Newton using diffraction through prisms demonstrated that light was composed of the visible spectrum, while findings of William Herschel in the 19th century showed that light also consisted of infrared rays. Joseph von Fraunhofer would later come to discover that by magnifying the spectrum of visible light, gaps in the spectrum would be observed.

    In 1905, Albert Einstein gained world fame for supposedly being the first scientist to successfully describe this effect. His theory was that light had little packets (quanta) of energy, or photons, and when exposed to metallic objects at certain frequencies the electrons in these metallic objects would absorb this energy and be broken off from their source. Hence, photoelectrons.

    But Tesla’s views on these effects were much different-

     He considered all conclusions incontrovertible, and with these results, Tesla believed it probable that there is a continuous supply of such radiations in the medium in some form which must come from the sun. Later experiments with the above conclusion would lead Tesla to his discovery of cosmic rays, which he also discovered come from not only our sun, but from every other star outside our solar system. This discovery would be fifteen years before Victor Hess, who also won a Nobel Prize for this discovery, who even today we still recognize as the discoverer of cosmic rays. 

    Nikola Tesla and the True Explanation of the Photoelectric Effect


    If a hypothetical photovoltaic device has an external quantum efficiency of 100 percent, that means that every photon of light that strikes it generates one electron, which exits through the circuit and is harvested as electricity.
