PV cells are electrically connected in a packaged, weather-tight PV panel (sometimes called a module). Below, you can find resources and information on the. . A photovoltaic (PV) cell, commonly called a solar cell, is a nonmechanical device that converts sunlight directly into electricity. Sunlight is composed of photons, or particles of solar energy. The two dissimilar semiconductors possess a natural difference in electric potential (voltage), which causes the electrons to flow through the external circuit, supplying power to the load.
