Photovoltaic effect

The photovoltaic effect is a process that generates voltage or electric current in a photovoltaic cell when it is exposed to sunlight. It is this effect that makes solar panels useful, as it is how the cells within the panel convert sunlight to electrical energy. The photovoltaic effect was first discovered in 1839 by Edmond Becquerel.

What causes the photoelectric vs photovoltaic effect?

It mainly depends on the material type due to the bonds that are formed in each material. The photoelectric effect where a photon excites an electron out of a metal, usually the electron is not hardly bounded within the material due to the nature of electrons in metal of being free electrons in metallic bonds means that in the case of excitement most of the electrons

The Photoelectric Effect

The photoelectric effect is a phenomenon in which electrons are ejected from the surface of a metal when light is incident on it. These ejected electrons are called photoelectrons is important to note that the emission of photoelectrons and the kinetic energy of the ejected photoelectrons is dependent on the frequency of the light that is incident on the metal''s surface.

Does the internal photoelectric effect produce photoelectrons?

The internal photoelectric effect does not produce photoelectrons which are observable outside the material, but only excites electrons to higher levels, namely from the valence band to the conduction band in a semiconductor material.

Photovoltaic Effect: An Introduction to Solar Cells
