Nasa Solar Panels In Space

The international space station has four solar arrays which produce more power than the station needs at one time for station systems and experiments.

Nasa solar panels in space.

Regular silicon cells were used first until gallium arsenide made it out of r d in the 90s. Nasa has taken an interest in solar for a long time. Each wing contains around 33 000 solar cells which convert about 14 percent of the sunlight that hits them into usable energy source. While the very first satellites were battery powered solar arrays became common in orbit by the 60s.

The solar arrays produce more power than the station needs at one time for station systems and experiments. One of humankind s most ambitious projects the international space station iss is dwarfed by the size of its eight 114 foot 35 meter long solar array wings. 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.

Now almost everything arriving in the ionosphere is multi junction. Engineers lyndsey mcmillon brown and timothy peshek are leading a project to test perovskite solar cells which could be an alternative to silicon solar cells currently used in space.
