2. Diffractive solar sail - Wikipedia

   en.wikipedia.org/wiki/Diffractive_solar_sail

   A diffractive solar sail, or diffractive lightsail, is a type of solar sail which relies on diffraction instead of reflection for its propulsion. [ 1 ] [ 2 ] Current diffractive sail designs use thin metamaterial films, containing micrometer-size gratings based on polarization or subwavelength refractive structures, causing light to spread out ...

3. Light tube - Wikipedia

   en.wikipedia.org/wiki/Light_tube

   The pipe is coated with a 99.3% specular reflective film and the distribution element at the end of the light pipe consists of a 4.6 m long diffusing radial film with an 87% visible transmittance. The light pipe introduces consistently illuminance levels ranging between 300 and 2,500 lux throughout the year at distances between 7.6 m to 10 m. [12]

4. Passive daytime radiative cooling - Wikipedia

   en.wikipedia.org/wiki/Passive_daytime_radiative...

   PDRC surfaces can be integrated with solar energy plants, referred to as solar energy–radiative cooling (SE–RC), to improve functionality and performance by preventing solar cells from 'overheating' and thus degrading. Since silicon solar cells have a maximum efficiency of 33.7% (with the average commercial panel reaching around 20%), the ...

5. Reflective surfaces (climate engineering) - Wikipedia

   en.wikipedia.org/wiki/Reflective_surfaces...

   The albedo of several types of roofs (lower values means higher temperatures). Reflective surfaces, or ground-based albedo modification (GBAM), is a solar radiation management method of enhancing Earth's albedo (the ability to reflect the visible, infrared, and ultraviolet wavelengths of the Sun, reducing heat transfer to the surface).

6. Solar radiation modification - Wikipedia

   en.wikipedia.org/wiki/Solar_radiation_modification

   Schematic with five proposed methods for solar radiation modification technologies. Solar radiation modification (SRM) (or solar radiation management or solar geoengineering), is a group of large-scale approaches to limit global warming by increasing the amount of sunlight (solar radiation) that is reflected away from Earth and back to space.

7. Space sunshade - Wikipedia

   en.wikipedia.org/wiki/Space_sunshade

   A sunshade could potentially be one climate engineering method for mitigating global warming through solar radiation management, because internationally negotiated reductions in carbon emissions may be insufficient to stem climate change. [5] [6] Sunshades could also be used to produce space solar power, acting as solar power satellites ...

9. Thin-film solar cell - Wikipedia

   en.wikipedia.org/wiki/Thin-film_solar_cell

   Thin-film solar cells, a second generation of photovoltaic (PV) solar cells: Top: thin-film silicon laminates being installed onto a roof. Middle: CIGS solar cell on a flexible plastic backing and rigid CdTe panels mounted on a supporting structure Bottom: thin-film laminates on rooftops Thin-film solar cells are a type of solar cell made by depositing one or more thin layers (thin films or ...
