Photovoltaics (PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry.

Learn more about how PV works. The U.S. Department of Energy Solar Energy Technologies Office (SETO) supports PV research and development projects that drive down the costs of solar-generated electricity by improving efficiency and reliability.

2024年5月24日 · Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. Source: National Renewable Energy Laboratory (copyrighted)

Learn the basics of how photovoltaic (PV) technology works with these resources from the DOE Solar Energy Technologies Office.

2024年7月25日 · Solar PV systems generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many photovoltaic cells within a single solar module, and the current created by all of the cells together adds up to enough electricity to help power your home.

Solar technologies convert sunlight into electrical energy either through photovoltaic (PV) panels or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage.

A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.

2024年12月12日 · Solar cells, also called photovoltaic cells, convert sunlight directly into electricity. Photovoltaics (often shortened as PV) gets its name from the process of converting light (photons) to electricity (voltage), which is called the photovoltaic effect.

Photovoltaics (PVs) are arrays of cells containing a solar photovoltaic material that converts solar radiation or energy from the sun into direct current electricity.

Photovoltaics (PVs) is defined by the conversion of light into electricity by two types of semiconductors, serving as a donor and acceptor respectively under the light excitation, which generates voltage and electric current in a circuit.
