How old are quantum dots? They seem ripe to replace this. Instead of trying to capture all the spectrum in multiple layers; capture one wavelength efficiently and convert the rest with quantum dots.

They did similar shit with phosphors back in the day.

Quantum dot solar cells are a long way off commercialisation. They are difficult to reliably produce at scale.

Is it the lack of sufficient spectrum coverage? Certainly Red and Green are commercially viable since they’re hitting TVs.

Does anyone know what primary spectrum of current PVs absorb is? If quantum dots let us focus on high energy blues and violets/ultraviolets then it could be worth it from cell degradation alone. Assuming the quantum dots don’t deteriorate over time. I have no idea, I just assume they’re solid state since they are allegedly better than phosphors.
