6 FAQs about [Photovoltaic field effect]
What is the 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.
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 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.
What is a photovoltaic (PV) cell?
A photovoltaic (PV) cell is an energy harvesting technology, that converts solar energy into useful electricity through a process called the photovoltaic effect. There are several different types of PV cells which all use semiconductors to interact with incoming photons from the Sun in order to generate an electric current.
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. This article was most recently revised and updated by William L. Hosch.
Why is efficiency a design concern for photovoltaic cells?
Efficiency is a design concern for photovoltaic cells, as there are many factors that limit their efficiency. The main factor is that 1/4 of the solar energy to the Earth cannot be converted into electricity by a silicon semiconductor.
