  2. Thermophotovoltaic energy conversion - Wikipedia

    en.wikipedia.org/wiki/Thermophotovoltaic_energy...

    Thermophotovoltaic (TPV) energy conversion is a direct conversion process from heat to electricity via photons.A basic thermophotovoltaic system consists of a hot object emitting thermal radiation and a photovoltaic cell similar to a solar cell but tuned to the spectrum being emitted from the hot object.

  3. Solar energy conversion - Wikipedia

    en.wikipedia.org/wiki/Solar_energy_conversion

    The use of selenium was highly inefficient, but it proved Becquerel's theory that light could be converted into electricity through the use of various semi-metals on the periodic table, that were later labelled as photo-conductive material. By 1953, Calvin Fuller, Gerald Pearson, and Daryl Chapin discovered the use of silicon to produce solar ...

  4. Artificial photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Artificial_photosynthesis

    An advantage of artificial photosynthesis would be that the solar energy could converted and stored. By contrast, using photovoltaic cells, sunlight is converted into electricity and then converted again into chemical energy for storage, with some necessary losses of energy associated with the second conversion. The byproducts of these ...

  5. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    Photons in sunlight hit the solar panel and are absorbed by semi-conducting materials.; Electrons (negatively charged) are knocked loose from their atoms as they are excited. . Due to their special structure and the materials in solar cells, the electrons are only allowed to move in a single directi

    Friction is the least-used of the six methods of producing energy. If a cloth rubs against an object, the object will display an effect called friction electricity. The object becomes charged due to the rubbing process, and now possesses an static electrical charge, hence it is also called static electricity. There are two main types of ...

    In 2023, solar power generated 5.5% (1,631 TWh) of global electricity and over 1% of primary energy, adding twice as much new electricity as coal. [ 65 ] [ 66 ] Along with onshore wind power , utility-scale solar is the source with the cheapest levelised cost of electricity for new installations in most countries.

  9. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    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. The photovoltaic effect is commercially used for electricity generation and as photosensors.
