Die Wissenschaftler brechen die Effizienzgrenze für Solarzellen-Shockley-Queisser-von 33,7% auf 50-60%-für eine einzelne Silizium-Solarzelle in Experiment, indem die Temperaturen auf 25-50k fallengelassen werden
Scientists break Shockley-Queisser efficiency limit for silicon solar cell in experiment

Does that include dropping the temperature to 50K in the efficiency measure?
This sounds useless but can be quite helpful on cold distant planets I assume ?
I am not certain this is applicable technology in our current world, but this is futurology…

However, this is the first time I have ever heard about the Shockley limit being broken. Of course, „if stand solar cells collapse as energy carriers become trapped“, these words might not matter anymore.
As well, today, this might not matter because of things like multi layer chips that these days are being developed – but who knows in the future?
How cold is it in space in our lower orbit? Higher orbit? Would this be feasible for huge space solar panels? Beaming down energy to the earth?
Oh good, how practical this is for terrestrial deployment… Thanks guys.
