A photovoltaic cell is the most critical part of a solar panel that allows it to convert sunlight into electricity. Sunlight is composed of photons, or particles of solar energy. Below, you can find resources and information on the. . Solar energy can be harnessed two primary ways: photovoltaics (PVs) are semiconductors that generate electricity directly from sunlight, while solar thermal technologies use sunlight to heat water for domestic uses, to warm buildings, or heat fluids to drive electricity-generating turbines. 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.
