Space · AM0 spectrum
HighLIGHT AM0
Outside the atmosphere there is no air-mass attenuation: the AM0 spectrum is bluer and stronger than AM1.5, at roughly 1367 W/m². HighLIGHT AM0 reproduces it faithfully to characterise the space-qualified cells that have to work the first time, and every time, in orbit.

The spectrum above the atmosphere
AM0, the sun before the sky changes it.
Earth's atmosphere absorbs and scatters specific bands; a satellite never sees that filtering. Qualifying space hardware means reproducing AM0 across every sub-cell's response band, so the measured efficiency is what the cell will actually deliver in orbit.

From cell to qualification
The measurement space programmes rely on.
Pasan AM0 systems characterise single-junction and multi-junction space cells with the accuracy mission power budgets demand, the foundation for the larger SAT platform that tests full multi-junction arrays.
