  2. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    Solar panel. A solar panel is a device that converts sunlight into electricity by using photovoltaic (PV) cells. PV cells are made of materials that produce excited electrons when exposed to light. The electrons flow through a circuit and produce direct current (DC) electricity, which can be used to power various devices or be stored in ...

  3. Perovskite solar cell - Wikipedia

    en.wikipedia.org/wiki/Perovskite_solar_cell

    A perovskite solar cell ( PSC) is a type of solar cell that includes a perovskite-structured compound, most commonly a hybrid organic–inorganic lead or tin halide-based material as the light-harvesting active layer. [ 1][ 2] Perovskite materials, such as methylammonium lead halides and all-inorganic cesium lead halide, are cheap to produce ...

  4. 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.

    In 2023, utility-scale solar power generated 164.5 terawatt-hours (TWh), or 3.9% of electricity in the United States. Total solar generation that year, including estimated small-scale photovoltaic generation, was 238 TWh. [ 2] As of the end of 2023, the United States had 179 gigawatts (GW) of installed photovoltaic (utility and small scale) and ...

  7. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    Solar panels on the International Space Station. Photovoltaics ( PV) is the conversion of light into electricity using semiconducting materials that exhibit the photovoltaic effect, a phenomenon studied in physics, photochemistry, and electrochemistry. The photovoltaic effect is commercially used for electricity generation and as photosensors .
