    Photovoltaic or PV cells convert light into electricity.  PV cells are made from semiconductors such as silicon; the semiconductor absorbs some of the sunlight that hits it, and the light becomes energy in the semiconductor.  This energy loosens electrons.  In addition to a semiconductor, PV cells have an electric field to guide electrons in one direction, causing a current.  Metal contacts are placed on top and on bottom of the PV cell so that the current can be put to external use.
