  2. Celiac plexus - Wikipedia

    en.wikipedia.org/wiki/Celiac_plexus

    The celiac plexus is often popularly referred to as the solar plexus. In the context of sparring or injury, a strike to the region of the stomach around the celiac plexus is commonly called a blow "to the solar plexus". In this case it is not the celiac plexus itself being referred to, but rather the region around it.

  3. Unpolarized light - Wikipedia

    en.wikipedia.org/wiki/Unpolarized_light

    Unpolarized light can be produced from the incoherent combination of vertical and horizontal linearly polarized light, or right- and left-handed circularly polarized light. [1] Conversely, the two constituent linearly polarized states of unpolarized light cannot form an interference pattern, even if rotated into alignment (Fresnel–Arago 3rd ...

  4. Photovoltaic effect - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_effect

    The first demonstration of the photovoltaic effect, by Edmond Becquerel in 1839, used an electrochemical cell. He explained his discovery in Comptes rendus de l'Académie des sciences, "the production of an electric current when two plates of platinum or gold immersed in an acid, neutral, or alkaline solution are exposed in an uneven way to solar radiation."

  5. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system , in combination with latitude and climate, determines the annual energy output of the system.

  6. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    The theory of solar cells explains the process by which light energy in photons is converted into electric current when the photons strike a suitable semiconductor device. The theoretical studies are of practical use because they predict the fundamental limits of a solar cell , and give guidance on the phenomena that contribute to losses and ...

  7. Solar Plexus - Wikipedia

    en.wikipedia.org/wiki/Solar_Plexus_(disambiguation)

    The celiac plexus (or solar plexus) is a complex network of nerves located in the abdomen. Solar plexus or Solar Plexus may also refer to: The solar plexus chakra in Hinduism, see Manipura

  8. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    It is a form of photoelectric cell, a device whose electrical characteristics (such as current, voltage, or resistance) vary when it is exposed to light. Individual solar cell devices are often the electrical building blocks of photovoltaic modules, known colloquially as "solar panels".

  9. Solar energy - Wikipedia

    en.wikipedia.org/wiki/Solar_energy

    Solar energy is the radiant energy from the Sun's light and heat, which can be harnessed using a range of technologies such as solar electricity, solar thermal energy (including solar water heating) and solar architecture.
