Electrons catapult across solar materials in just 18 femtoseconds
General • March 5, 2026
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 boundary 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.
