Electrons in solar materials can be launched across molecules almost as fast as nature allows, thanks to tiny atomic vibrations acting like a “molecular catapult.” In experiments lasting just 18 femtoseconds, researchers at the University of Cambridge observed electrons blasting across a boundar y in a single burst, far faster than long-standing theories predicted. Instead of slow, random movement, the electron rides the natural vibrations of the molecule itself, challenging decades of design rules for solar materials. ...read more read less
