Possible source: Solar panels with this material were hyped a couple years ago.

Ah, that's what it was for me.

Perovskite solar cells, ah yes, the ones that degrade rapidly in sunlight. Good thing they are typically safely tucked away in labs with controlled lighting.

Idk what you're trying to say. Every technology starts in a lab. Perhaps the degradation problem is solvable?

It’s just a mindless comment by someone who doesn’t keep up with the latest developments. Perovskites already entered small scale commercial production last year and are being deployed in the field to validate how well they hold up in real-world conditions, so it seems we’re only one step away from large-scale deployment.

IIRC it was some different type of imaging sensor, so looked it up that way

They are used in thin-film solar panel development. Not sure anyone has cracked the big problem with them, which is durability.

You may have a Perovskia growing in the garden also. The brothers left their print.
