Perovskite PV...not an easy nut to crack:

*No mention in this particular article of alternative QD-perovskite formulas currently being researched in this zone, but it gives a well-stated picture of where things stand across the board...incl names, capabilities & status of players. 'Lead' seems to be seen as a significant stumbling block...perhaps somewhat akin to the CdSe formula restrictions that ultimately killed-off CdQd solar & LED via RoHs[?]. Meanwhile; there continues to be a lot of ongoing research into perovskite-QD formulas, both lead & lead-free:
On the other hand currently, this one example using aluminum w/ perovskite -QD's brings in a PCE (power conversion efficiency) of 18.02%: https://onlinelibrary.wiley.com/doi/abs/10.10....201900041
...and this one adding PbSQD's into the mix, to a total of 19.24%PCE: https://www.sciencedirect.com/science/article...3219313741
...yet this one shows a 'lead free' formula with a paltry 5.03% PCE: https://pubs.rsc.org/en/content/articlelandin...ivAbstract
