Quick Answer: Which type of solar cells are used in space application?

What solar cells do NASA use?

SolAero Technologies

Solar cells manufactured by SolAero range from 28 – 32% average efficiency and have extensive flight heritage on both large and small spacecraft. SolAero also manufactures 27% – 29.5% efficiency solar cells (BJT, ATJ, and ZTJ) that are fully space qualified for small spacecraft missions (9).

Which material is used in space solar panels and why?

Silicon solar cells have proved to be suitable for use in space applications, despite their own limitations. Silicon cells have generally lower efficiencies and significant radiation damage than others new materials.

Which cells are used in spacecraft?

Alkaline fuel cells have been the primary source of electrical power on human spaceflight systems for over four decades. However, alkaline fuel cells use a costly, aging technology.

How are space solar panels made?

Solar arrays that convert energy to electricity on the International Space Station are made of thousands of solar cells, made from purified chunks of the element silicon. These cells directly convert light to electricity using a process called photovoltaics.

Is polycrystalline or monocrystalline better?

Monocrystalline solar cells are more efficient because they are cut from a single source of silicon. Polycrystalline solar cells are blended from multiple silicon sources and are slightly less efficient. Thin-film technology costs less than mono or poly panels, but is also less efficient.
