    en.wikipedia.org/wiki/Solar_cell

    A solar cell, also known as a 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.

    en.wikipedia.org/wiki/Theory_of_solar_cells

    The electronic structure of the materials is very important for the process to work, and often silicon incorporating small amounts of boron or phosphorus is used in different layers. An array of solar cells converts solar energy into a usable amount of direct current (DC) electricity.

  4. Photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Photovoltaics

    A basic thermophotovoltaic system consists of a hot object emitting thermal radiation and a photovoltaic cell similar to a solar cell but tuned to the spectrum being emitted from the hot object. [140] As TPV systems generally work at lower temperatures than solar cells, their efficiencies tend to be low.

  5. Solar power - Wikipedia

    en.wikipedia.org/wiki/Solar_power

    A solar cell, or photovoltaic cell, is a device that converts light into electric current using the photovoltaic effect. The first solar cell was constructed by Charles Fritts in the 1880s. [13] The German industrialist Ernst Werner von Siemens was among those who recognized the importance of this discovery. [14]

    en.wikipedia.org/wiki/Photovoltaic_effect

    The first demonstration of the photovoltaic effect, by Edmond Becquerel in 1839, used an electrochemical cell. He explained his discovery in Comptes rendus de l'Académie des sciences, "the production of an electric current when two plates of platinum or gold immersed in an acid, neutral, or alkaline solution are exposed in an uneven way to solar radiation."

  7. Photovoltaic system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_system

    A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...

  8. Multi-junction solar cell - Wikipedia

    en.wikipedia.org/wiki/Multi-junction_solar_cell

    There are four main categories of photovoltaic cells: conventional mono- and poly-crystalline silicon (c-Si) cells, thin film solar cells (a-Si, CIGS and CdTe), and multi-junction (MJ) solar cells. The fourth category, emerging photovoltaics , contains technologies that are still in the research or development phase and are not listed in the ...
