Summary

Story summary

Researchers at the University of Cambridge identified a mechanism enabling charge transfer in solar materials in 18 femtoseconds.
The finding challenges the traditional belief that ultrafast transfer requires large energy differences and strong electronic interactions.
Molecular vibrations actively propel electrons, effectively acting as a catapult.
This suggests a design principle to engineer materials that use molecular vibrations to boost solar efficiency.
