Triple junction device.

Let me know when they do this on a single junction…

The Shockley Quiesser theoretical limit for single junctions is at ~33%.

Yes. True. The amount of effort to even approach that and the insane amount of energy in purifying the precursors or chemically creating the precursors is insane. Cradle to grave- the use case is limited. And you’re right we’ll likely never even approach the SQ limit. But even if we did it would still be a losing energy proposition.

mrw somebody invents a material with a complex bandgap that breaks the shockley queisser limit

What does the number of junctions matter as long as long as it can be manufactured cheaply?
