The TL;DR for those wondering, how the physics this works:

The cell selectively harnesses a portion of the solar spectrum that is invisible to the naked eye, while allowing the normal visible light to pass through.

This seems really neat. Future buildings will look like the ones in Titanfall lol.

I think I remember reading about this a few years back when it was fresh in concept - and if I recall correctly there were some concerns resource-efficiency wise that would make deploying it on a large scale unfeasible in the discussion. But, yeah, I am unsure, it’s been a few years and I shelved it in the back of my head. Maybe someone else knows more?
