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.

Thanks for the info

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

Worse the the status Quo though?
