The main issue is with longevity, once they solve that, I am hopeful they will then this will dominate the Solar market completely and replace all the Silicon based single band gap panels. Even someone with relatively recent panels of 20-22% would benefit a lot from 35% panels, that is a lot of extra power in the same space.

Is longevity currently a deal breaker?

Asking because I'm pretty sure just saw an article about solar panels from the 90s that were still working at 70+% capacity

It's an issue for perovskite cells. "Traditional" silicon cells (which makes up probably 90+% of current installs) last 40+ years.

Longevity issues combined with harmful rare mineral extraction kinda eats ass in the long run

Worse the the status Quo though?
