In tiny perovskite crystals, physicists saw the reverse of synchronized light emission: a coordinated light absorption that works even at room temperature.

A crystal can flash light in perfect sync—like an orchestra hitting a chord. Now, physicists have seen the reverse: a synchronized light gulp. This 'superabsorption' works in cheap perovskite dots at room temperature. Could lead to solar panels that catch every photon.

🎯 The cooperative absorption happens 10 trillion times faster than the blink of an eye.

🎬 In science fiction, perfect light absorbers enable cloaking devices or endless energy; this discovery might bring that fantasy closer to reality.
