  2. Photosynthetic efficiency - Wikipedia

    en.wikipedia.org/wiki/Photosynthetic_efficiency

    68% of the used energy is lost in conversion into d-glucose; 35–45% of the glucose is consumed by the leaf in the processes of dark and photo respiration; Stated another way: 100% sunlight → non-bioavailable photons waste is 47%, leaving; 53% (in the 400–700 nm range) → 30% of photons are lost due to incomplete absorption, leaving

  3. Photosynthesis - Wikipedia

    en.wikipedia.org/wiki/Photosynthesis

    Photosynthesis (/ ˌ f oʊ t ə ˈ s ɪ n θ ə s ɪ s / FOH-tə-SINTH-ə-sis) [1] is a system of biological processes by which photosynthetic organisms, such as most plants, algae, and cyanobacteria, convert light energy, typically from sunlight, into the chemical energy necessary to fuel their metabolism.

  4. Solar core - Wikipedia

    en.wikipedia.org/wiki/Solar_core

    The core produces almost all of the Sun's heat via fusion; the rest of the star is heated by the outward transfer of heat from the core. The energy produced by fusion in the core, except a small part carried out by neutrinos , must travel through many successive layers to the solar photosphere before it escapes into space as sunlight , or else ...

  5. Sunlight - Wikipedia

    en.wikipedia.org/wiki/Sunlight

    Sunlight is a key factor in photosynthesis, the process used by plants and other autotrophic organisms to convert light energy, normally from the Sun, into chemical energy that can be used to synthesize carbohydrates and fuel the organisms' activities. Daylighting is the natural lighting of interior spaces by admitting sunlight.

  6. Solar energy conversion - Wikipedia

    en.wikipedia.org/wiki/Solar_energy_conversion

    This energy can be used for water heating, space heating, space cooling and process heat generation. Many steam generation systems have adapted to using sunlight as a primary source for heating feed water, a development that has greatly increased the overall efficiency of boilers and many other types of waste heat recovery systems.

  7. Shockley–Queisser limit - Wikipedia

    en.wikipedia.org/wiki/Shockley–Queisser_limit

    The electron is ejected with higher energy when struck by a blue photon, but it loses this extra energy as it travels toward the p-n junction (the energy is converted into heat). [10] This accounts for about 33% of the incident sunlight, meaning that, for silicon, from spectrum losses alone there is a theoretical conversion efficiency limit of ...

    Average mortgage rates edge higher for 30-year and 15-year terms as of Wednesday, December 18, 2024, as the Federal Reserve is set to conclude its final policy session of the year.

  9. Outline of solar energy - Wikipedia

    en.wikipedia.org/wiki/Outline_of_solar_energy

    Thermophotovoltaic (TPV) – energy conversion is a direct conversion process from heat differentials to electricity via photons. Polycrystalline silicon photovoltaics – are a type of solar cell. Thermodynamic efficiency limit – the absolute maximum theoretically possible conversion efficiency of sunlight to electricity.
