Photovoltaic Cells Convert Sunlight Into ElectricityThe Flow of Electricity in A Solar CellPV Cells, Panels, and ArraysPV System EfficiencyPV System ApplicationsHistory of PV SystemsA photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Some PV cells can convert artificial light into electricity. Sunlight is composed of photons, or particles of solar energy. These photons contain varying amounts of energy that correspond to the different wavelengths o...See more on eia.govPublished: Oct 1, 2024
