small samples can achieve ridiculous efficiencies. @ me when they 1. can scale this thing to entire panel, and 2. lasts longer than it takes to get it out of lab. silicon can pull 22% and more, scales reliably and lasts longer. also, it's a bunch of marketing fluff, linked to other marketing fluff. if there's anything real, you could just post DOI
also does it contain lead? i bet it does, but there are no details at all
Lead isn't a problem if it's contained, but there needs to be a disposal plan.
from everything i've learned about chemical waste management and recycling, no it won't remain contained
