Summary

Story summary

Researchers from Kyushu University and Johannes Gutenberg University have developed a solar energy technology that surpasses traditional efficiency limits.
They used a molybdenum-based spin-flip emitter to reach 130% quantum yield, enabling one photon to produce energy of two.
The approach uses singlet fission to split excitons, overcoming the Shockley-Queisser limit.
The team plans to integrate the technology into solid-state systems for solar cells, LEDs, and quantum technologies.
