  2. 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 ...

  3. Building-integrated photovoltaics - Wikipedia

    en.wikipedia.org/wiki/Building-integrated...

    Building-integrated photovoltaics (BIPV) are photovoltaic materials that are used to replace conventional building materials in parts of the building envelope such as the roof, skylights, or façades. [1] They are increasingly being incorporated into the construction of new buildings as a principal or ancillary source of electrical power ...

    en.wikipedia.org/wiki/Solar_power_in_the_United...

    Solar potential. The UK's annual insolation is in the range of 750–1,100 kilowatt-hours per square metre (kWh/m 2). London receives 0.52 and 4.74 kWh/m 2 per day in December and July, respectively. [5] While the sunniest parts of the UK receive much less solar radiation than the sunniest parts of Europe, the country's insolation in the south ...

  5. Solar panel - Wikipedia

    en.wikipedia.org/wiki/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 batteries.

  6. 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.

  7. Solar-cell efficiency - Wikipedia

    en.wikipedia.org/wiki/Solar-cell_efficiency

    Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system , in combination with latitude and climate, determines the annual energy output of the system.

  8. Thermophotovoltaic energy conversion - Wikipedia

    en.wikipedia.org/wiki/Thermophotovoltaic_energy...

    Thermophotovoltaic energy conversion. Thermophotovoltaic (TPV) energy conversion is a direct conversion process from heat to electricity via photons. 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.

  9. List of types of solar cells - Wikipedia

    en.wikipedia.org/wiki/List_of_types_of_solar_cells

    A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect, which is a physical and chemical phenomenon. It is a form of photoelectric cell, defined as a device whose electrical characteristics, such as current ...
