  2. Schottky junction solar cell - Wikipedia

    en.wikipedia.org/wiki/Schottky_junction_solar_cell

    In a basic Schottky-junction (Schottky-barrier) solar cell, an interface between a metal and a semiconductor provides the band bending necessary for charge separation. [1] Traditional solar cells are composed of p-type and n-type semiconductor layers sandwiched together, forming the source of built-in voltage (a p-n junction ). [ 2 ]

  3. 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 ...

  4. Amorphous silicon - Wikipedia

    en.wikipedia.org/wiki/Amorphous_silicon

    Amorphous silicon (a-Si) is the non-crystalline form of silicon used for solar cells and thin-film transistors in LCDs. Used as semiconductor material for a-Si solar cells, or thin-film silicon solar cells, it is deposited in thin films onto a variety of flexible substrates, such as glass, metal and plastic. Amorphous silicon cells generally ...

    The demand for cheaper, greener electricity means that the energy landscape is changing faster than at any other point in history. This is particularly true of solar-powered electricity and ...

  6. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series creating additive voltage. Connecting ...

  7. Multi-junction solar cell - Wikipedia

    en.wikipedia.org/wiki/Multi-junction_solar_cell

    Multi-junction (MJ) solar cells are solar cells with multiple p–n junctions made of different semiconductor materials. Each material's p–n junction will produce electric current in response to different wavelengths of light .

  8. Heterojunction solar cell - Wikipedia

    en.wikipedia.org/wiki/Heterojunction_solar_cell

    In 2017, tandem solar cells using a SHJ bottom cell and Group III–V semiconductor top cells were fabricated with power conversion efficiencies of 32.8% and 35.9% for 2- and 3-junction non-monolithic stacks respectively.

  9. Monocrystalline silicon - Wikipedia

    en.wikipedia.org/wiki/Monocrystalline_silicon

    With a recorded single-junction cell lab efficiency of 26.7%, monocrystalline silicon has the highest confirmed conversion efficiency out of all commercial PV technologies, ahead of poly-Si (22.3%) and established thin-film technologies, such as CIGS cells (21.7%), CdTe cells (21.0%), and a-Si cells (10.2%). Solar module efficiencies for mono ...
