HighLIGHT SAT
Multi-junction 3/4/5J
The sun, the way a satellite sees it, at array scale. HighLIGHT SAT is a large-area AM0 platform for the multi-junction cells and panels that power spacecraft, current-matching every junction so the limiting current and the true efficiency are what you measure, not an artefact of the lamp.
AM0 · 3J / 4J / 5J · cell to panel
Every junction, current-matched.
A 3J, 4J or 5J stack only performs when its sub-cells are balanced. SAT illuminates each junction's band correctly so the limiting current, and the true efficiency, is what you measure, with junction-specific I–V, Jsc, Voc and fill factor.

The only large-area multi-junction platform.
SAT scales AM0 measurement from a single cell to a complete satellite panel, the industrial-scale platform space programmes use to qualify arrays and assess reliability margin before launch.
