"So far, we haven't been able to make these materials stable with the bandgap we need, so we've been trying to immobilise the ion movement by tweaking the chemical composition of the perovskite layers," said Dr Sam Stranks from Cambridge's Cavendish Laboratory, who led the research. "This would enable perovskites to be used as versatile solar cells or as coloured LEDs, which are essentially solar cells run in reverse."

If you read QMC perovskite PR they make the point -
Perovskite quantum dots are leading a breakthrough in materials technology, but the commercialization of these materials has been hampered due to inabilities to produce large volumes of these materials at low cost points while still achieving long term reliability. Quantum Materials Corp has developed a high volume production process that produces extremely high purity PQDs with significantly improved stability.

My point is that noone has made perovskite QD like this before.
You can't go by ANY perovskite research papers to define this QMC perovskite QD.
Everyone is still trying to perfect a perovskite QD on established methods.
QMC threw all that out and started from scratch.
Further point -my belief is that these perovskite QD share the advantages of other types of QMC QD made by continuous flow reactor. The process is so different from all other methods that the industry is not aware of its capabilities.
