Tesla 3 Solar Roof

Not much detail yet, but my guess is it’s something like this:

Imagine this:
* Center layer contains IR fluorescing organic salts
* Refractors bend the new IR out to the edges
* Edges are high efficiency NIR photovoltaic cells.
* Inside layer would be reflective coated on the outer face.

This would reduce IR ingress during sunny days, and convert IR and UV to electricity.
The black edges could also be monocrystalline PV cells in the visible spectrum.

I think you could expect a few hundred watts during a sunny TX day, which would be enough to keep things topped off between short commutes.
