  2. Zinc–carbon battery - Wikipedia

    en.wikipedia.org/wiki/Zinc–carbon_battery

    The zinc-chloride cell, frequently referred to as a heavy-duty, extra-heavy-duty, super-heavy-duty, or super-extra-heavy-duty battery, is an improvement on the original zinc–carbon cell, using purer chemicals and giving a longer service life and steadier voltage output as it is used and offering about twice the service life of general-purpose ...

  3. Dye-sensitized solar cell - Wikipedia

    en.wikipedia.org/wiki/Dye-sensitized_solar_cell

    Dye-sensitized solar cell. A selection of dye-sensitized solar cells. A dye-sensitized solar cell ( DSSC, DSC, DYSC[ 1] or Grätzel cell) is a low-cost solar cell belonging to the group of thin film solar cells. [ 2] It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, a photoelectrochemical system.

  4. List of battery sizes - Wikipedia

    en.wikipedia.org/wiki/List_of_battery_sizes

    Some such circuits increase cell diameter instead. The increased dimensions may mean the cell will no longer fit in battery compartments intended for cells without such circuitry. Commonly-used designation numbers indicate the physical dimensions of the cylindrical cell, as given in IEC standard 60086-1 for cylindrical primary cells.

  5. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    Solar cell. A conventional crystalline silicon solar cell (as of 2005). Electrical contacts made from busbars (the larger silver-colored strips) and fingers (the smaller ones) are printed on the silicon wafer. Symbol of a Photovoltaic cell. A solar cell or photovoltaic cell ( PV cell) is an electronic device that converts the energy of light ...

  6. Sodium–sulfur battery - Wikipedia

    en.wikipedia.org/wiki/Sodium–sulfur_battery

    A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. [ 1][ 2] This type of battery has a similar energy density to lithium-ion batteries, [ 3] and is fabricated from inexpensive and non-toxic materials. However, due to the high operating temperature required (usually between 300 ...

  7. Nanocrystal solar cell - Wikipedia

    en.wikipedia.org/wiki/Nanocrystal_solar_cell

    Nanocrystal solar cell. Efficiency of different solar cells. Nanocrystal solar cells are solar cells based on a substrate with a coating of nanocrystals. The nanocrystals are typically based on silicon, CdTe or CIGS and the substrates are generally silicon or various organic conductors. Quantum dot solar cells are a variant of this approach ...

  8. Tesla Powerwall - Wikipedia

    en.wikipedia.org/wiki/Tesla_Powerwall

    The Tesla Powerwall is a rechargeable lithium-ion battery stationary home energy storage product manufactured by Tesla Energy. The Powerwall stores electricity for solar self-consumption, time of use load shifting, and backup power. [ 1][ 2] The Powerwall was introduced in 2015 as Powerwall 1 with limited production.

  9. 2011 in science - Wikipedia

    en.wikipedia.org/wiki/2011_in_science

    The solar-powered probe Juno is launched from Kennedy Space Center on a five-year mission to Jupiter. Bypassing stem cells, scientists have made neurons directly from human skin. Scientists have developed a new class of molecules that target cells' entry systems to ensure harmful organisms do not gain access.
