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.
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.

The circuit allows the electrons to flow to the electron-poor back of the cell from the electron-rich front of the cell. Photovoltaic panels are oriented to maximize the use of the sun’s light, and the system angles can be changed for winter and summer. When a panel is perpendicular to the sunlight, it intercepts the most energy.
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.
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.
