This is a combination of two different cells not one material

Currently most perovskites are based on Lead salts. So theyre cheap to manufacture but have obvious environmental issues
As long as they don’t leak lead, I don’t really see the problem.
the lead will be perfectly safe until someone crushes them up into a bunch of powder with a front loader, and then dumps in the nearest unsealed landfill
also lead mining/production is not waste free in of itself
Theyre lead salts. I guarantee that some of it is going to leech into the environment. And at some point theyre going to need to be manufactured in the first place and recycled/disposed of
The companies that make these need to provide free recycling for every panel they sell.

Oh great! I can’t wait to not see it or hear about it again just like all those other amazing breakthroughs 😭
A team from the Chinese solar technology firm Longi set a new world record of 33.9 per cent for a silicon-perovskite tandem solar cell, breaking the previous record set in May this year by King Abdullah University of Science & Technology (KAUST) in Saudi Arabia.
