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.
For convection cells on the sun's surface, see Granule (solar physics). See also: Photovoltaics. A conventional crystalline silicon solar cell (as of 2005). Electrical contacts made from busbars (the larger silver-colored strips) and fingers (the smaller ones) are printed on the silicon wafer.
