ISRO exports tech from US to produce solar cells for satellites in space
- ISRO will export technology from the US for mass production of
space solar cellsto power Indian satellites.
- Until now,
Indiawas procuring the solar cells from private American companies.
- This will make India more independent and will also reduce the expenses incurred because of the expensive exports.
Before the country decided to buy this technology, India was procuring solar cells from private American companies at rather expensive rates. Furthermore, there were restrictions on buying them in bulk. Our satellite programmes were completely dependant on these cells and without the tech to make more indigenously, there was little else to do but to count wholly on the transaction.
Producing a small remote-sensing satellite requires about 1,500 solar cells, while big satellites like
These satellites, once launched in space, open up their wings, that have the solar cells, to absorb sunlight and turn solar power to electricity. The satellite is kept up and functioning by these cells and will maintain power and working capacity unless the cells last. Once the cells die out, the satellite powers down, stops functioning and becomes space debri.
