It’s hard to overstate how wild perovskite materials really are. They look simple — just these thin, shimmering films — but inside, they’re doing things that used to sound impossible. They can absorb light better than silicon, emit light brighter than LEDs, and do both with almost no wasted energy. That’s not just incremental progress. That’s flipping the script on how materials behave. What makes them revolutionary isn’t one big breakthrough — it’s the combination of everyth
