  2. Biological photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Biological_photovoltaics

    Biological photovoltaic devices are a type of biological electrochemical system, or microbial fuel cell, and are sometimes also called photo-microbial fuel cells or “living solar cells”. [3] In a biological photovoltaic system , electrons generated by photolysis of water are transferred to an anode . [ 4 ]

  3. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    A solar cell, also known as a photovoltaic cell (PV cell), is an electronic device that converts the energy of light directly into electricity by means of the photovoltaic effect. [1] 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.

    The cradle to gate of CO 2-eq/kWh ranges from 37.3 to 72.2 grams when installed in Southern Europe. [68] Techniques to produce multi-crystalline silicon (multi-si) photovoltaic cells are simpler and cheaper than mono-si, however tend to make less efficient cells, an average of 13.2%. [66] EPBT ranges from 1.5 to 2.6 years. [67]

    en.wikipedia.org/wiki/List_of_prime_numbers

    This is a list of articles about prime numbers.A prime number (or prime) is a natural number greater than 1 that has no positive divisors other than 1 and itself. By Euclid's theorem, there are an infinite number of prime numbers.

  6. Double Mersenne number - Wikipedia

    en.wikipedia.org/wiki/Double_Mersenne_number

    Since a Mersenne number M p can be prime only if p is prime, (see Mersenne prime for a proof), a double Mersenne number can be prime only if M p is itself a Mersenne prime. For the first values of p for which M p is prime, M M p {\displaystyle M_{M_{p}}} is known to be prime for p = 2, 3, 5, 7 while explicit factors of M M p {\displaystyle M_{M ...

  7. Organic solar cell - Wikipedia

    en.wikipedia.org/wiki/Organic_solar_cell

    An organic solar cell (OSC [1]) or plastic solar cell is a type of photovoltaic that uses organic electronics, a branch of electronics that deals with conductive organic polymers or small organic molecules, [2] for light absorption and charge transport to produce electricity from sunlight by the photovoltaic effect.

  9. Theory of solar cells - Wikipedia

    en.wikipedia.org/wiki/Theory_of_solar_cells

    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 solar cell efficiency. Band diagram of a solar cell, corresponding to very low current (horizontal Fermi level), very low voltage (metal valence bands at same height), and ...
