A solar cell (or a "photovoltaic" cell) is a device that converts photons from the sun (solar light) into electricity.
In
general, a solar cell that includes both solar and nonsolar sources of
light (such as photons from incandescent bulbs) is termed a photovoltaic
cell.
Fundamentally, the device needs to fulfill only two
functions: photogeneration of charge carriers (electrons and holes) in a
light-absorbing material, and separation of the charge carriers to a
conductive contact that will transmit the electricity. This conversion
is called the photovoltaic effect, and the field of research related to
solar cells is known as photovoltaics. Solar cells have many
applications.
Historically solar cells have been used in
situations where electrical power from the grid is unavailable, such as
in remote area power systems, Earth orbiting satellites, consumer
systems, e.g. handheld calculators or wrist watches, remote
radio-telephones and water pumping.
