  2. Solar cell - Wikipedia

    en.wikipedia.org/wiki/Solar_cell

    A solar cell or 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.

  3. Solar cell fabric - Wikipedia

    en.wikipedia.org/wiki/Solar_cell_fabric

    Solar cell fabric is a fabric with embedded photovoltaic cells which generate electricity when exposed to light. Traditional silicon based solar cells are expensive to manufacture, rigid and fragile. Although less efficient, thin-film cells and organic polymer based cells can be produced quickly and cheaply.

  4. Photoactive layer - Wikipedia

    en.wikipedia.org/wiki/Photoactive_layer

    A photoactive layer is used in solar cells for absorbing light. It can be found in all solar cells, but with different panels the photoactive layer is made of different materials. Inorganic layers are made from inorganic materials such as silicon. The film has a layer arrangement of electrodes and counter electrode with organic layers in ...

    Used in photoresistors and solar cells; CdS/Cu 2 S was the first efficient solar cell. Used in solar cells with CdTe. Common as quantum dots. Crystals can act as solid-state lasers. Electroluminescent. When doped, can act as a phosphor. II-VI: 2: Cadmium telluride: CdTe: 1.49 [6] direct: Used in solar cells with CdS.

  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. 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 ...

  9. 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.
