  2. Solar panels on spacecraft - Wikipedia

    en.wikipedia.org/wiki/Solar_panels_on_spacecraft

    Concentrators work best when there is a single source of light and the concentrator can be pointed right at it. This is ideal in space, where the Sun is a single light source. Solar cells are the most expensive part of solar arrays, and arrays are often a very expensive part of the spacecraft.

  3. Space-based solar power - Wikipedia

    en.wikipedia.org/wiki/Space-based_solar_power

    collecting solar energy in space with reflectors or inflatable mirrors onto solar cells or heaters for thermal systems; wireless power transmission to Earth via microwave or laser; receiving power on Earth via a rectenna, a microwave antenna; The space-based portion will not need to support itself against gravity (other than relatively weak ...

  4. Thermophotovoltaic energy conversion - Wikipedia

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

    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. [1] As TPV systems generally work at lower temperatures than solar cells, their efficiencies tend to be low.

    International Space Station solar array wing (Expedition 17 crew, August 2008).An ISS solar panel intersecting Earth's horizon.. The electrical system of the International Space Station is a critical part of the International Space Station (ISS) as it allows the operation of essential life-support systems, safe operation of the station, operation of science equipment, as well as improving crew ...

  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. 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 ...

    An example of work on this type of technology is Advanced Electric Propulsion System. [5] The NASA Solar Technology Application Readiness (NSTAR) ion engine has been used with photovoltaic solar panels, which was tested on the Deep Space 1 mission along with Solar Concentrator Arrays (Launched in 1998 as part of the New Millennium Program).
