Context of '1916: Scientist Proves Photovoltaic Effect'

This is a scalable context timeline. It contains events related to the event 1916: Scientist Proves Photovoltaic Effect. You can narrow or broaden the context of this timeline by adjusting the zoom level. The lower the scale, the more relevant the items on average will be, while the higher the scale, the less relevant the items, on average, will be.

French scientist Edmond Becquerel, 19 years old, discovers the photovoltaic effect while experimenting with an electrolytic cell made up of two metal electrodes placed in an electricity-conducting solution. Becquerel’s experiment proves that heightened amounts of electricity can be generated when the cell is exposed to sunlight. He coins the term “photovoltaic effect” to describe his finding. Basically, the photovoltaic effect (PV) occurs when the energy from photons strikes a semiconducting material such as silicon or platinun, and transfers its energy to an atom of the semiconducting material. The energized electron then escapes its bond and generates an electric current. The “gap” created by the escaped electron works with the electron to create the current.

1905: Einstein Writes about Photoelectric Effect

Physicist Albert Einstein publishes a paper on the photoelectric effect. Unfortunately for the paper, another paper he publishes, on the theory of relativity, draws far more attention. In 1921, he will win the Nobel Prize for his work on the photoelectric effect. [US Department of Energy, 2002 pdf file]
