What is photovoltaic effect?

What is the difference between photoelectric effect and photovoltaic effect?

The main distinction is that the term photoelectric effect is now usually used when the electron is ejected out of the material (usually into a vacuum) and photovoltaic effect used when the excited charge carrier is still contained within the material.

Where does the photovoltaic effect occur?

The photovoltaic effect occurs in solar cells. These solar cells are composed of two different types of semiconductors - a p-type and an n-type - that are joined together to create a p-n junction. To read the background on what these semiconductors are and what the junction is, click here.

What is a photovoltaic current used for?

This current can be used to measure the brightness of the incident light or as a source of power in an electrical circuit, as in a solar power system (see solar cell). The photovoltaic effect in a solar cell can be illustrated with an analogy to a child at a slide.

How do photovoltaic panels work?

This effect is mainly activated by sunlight, although it can be triggered by natural or artificial light sources. However, in practice, the vast majority of photovoltaic panels use exclusively sunlight as an energy source.

Does photovoltaic effect produce a direct current?

The motion of the electron, like that of the child, is in one direction, as can be seen from the figure. In short, the photovoltaic effect produces a direct current (DC)—one that flows constantly in only a single direction. See also photoelectric effect.
