Solar cell. A solar cell, or photovoltaic cell (previously termed solar battery), is an electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon.
Solar cells are also called photovoltaic or photoelectric cells. Enough power can be generated to run a 100W light bulb from just one square meter of solar panel. Solar cells were originally developed in order to provide electricity for satellites.
