  2. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    NASA used solar cells on its spacecraft from the beginning, their second successful satellite Vanguard 1 (1958) featured the first solar cells in space. Solar cells were first used in a prominent application when they were proposed and flown on the Vanguard satellite in 1958, as an alternative power source to the primary battery power source ...

  3. Perovskite solar cell - Wikipedia

    en.wikipedia.org/wiki/Perovskite_solar_cell

    Crystal structure of CH 3 NH 3 PbX 3 perovskites (X=I, Br and/or Cl). The methylammonium cation (CH 3 NH 3 +) is surrounded by PbX 6 octahedra. [13]The name "perovskite solar cell" is derived from the ABX 3 crystal structure of the absorber materials, referred to as perovskite structure, where A and B are cations and X is an anion.

    Fig. 3: Examples of organic photovoltaic materials. A photovoltaic cell is a specialized semiconductor diode that converts light into direct current (DC) electricity. . Depending on the band gap of the light-absorbing material, photovoltaic cells can also convert low-energy, infrared (IR) or high-energy, ultraviolet (UV) photons into DC ele

  6. Thin-film solar cell - Wikipedia

    en.wikipedia.org/wiki/Thin-film_solar_cell

    In a typical solar cell, the photovoltaic effect is used to generate electricity from sunlight. The light-absorbing or "active layer" of the solar cell is typically a semiconducting material, meaning that there is a gap in its energy spectrum between the valence band of localized electrons around host ions and the conduction band of higher-energy electrons which are free to move throughout the ...

  7. Crystalline silicon - Wikipedia

    en.wikipedia.org/wiki/Crystalline_silicon

    First generation solar cells are made of crystalline silicon, also called, conventional, traditional, wafer-based solar cells and include monocrystalline (mono-Si) and polycrystalline (multi-Si) semiconducting materials. Second generation solar cells or panels are based on thin-film technology and are of commercially significant importance.
