The word Photovoltaic is a combination of the Greek Work for light and the name of the physicist Allesandro Volta. It refers to the direct conversion of sunlight into electrical energy by means of solar cells. So very simply, a photovoltaic (PV) cell is a solar cell that produces usable electrical energy.
Create a timeline showing developments in PV cell technology. Research a scientist who has been involved in the photoelectric effect or the development of photovoltaic technology and describe the importance of their achievements. Key Idea 4.1a All energy transfers are governed by the law of conservation of energy.
PV cells also all have one or more electric fields that act to force electrons freed by light absorption to flow in a certain direction. This flow of electrons is a current, and by placing metal contacts on the top and bottom of the PV cell, we can draw that current off to use externally.
Let's take a deeper look into one example of a PV cell: the single crystal silicon cell. Silicon has some special chemical properties, especially in its crystalline form. An atom of silicon has 14 electrons, arranged in three different shells. The first two shells, those closest to the center, are completely full.
Photovoltaic (PV) cells create electricity from sunlight and are one of the true success stories of materials science. Photovoltaic cells have grown from an area of study once viewed with skepticism to a multi-billion dollar market that promises tremendous continued growth.
Photovoltaic cells have grown from an area of study once viewed with skepticism to a multi-billion dollar market that promises tremendous continued growth. There are more than one billion hand-held calculators, several million watches and two or three million portable lights and battery chargers powered by PV cells.
