Researchers achieved a 130% energy yield from a single light source by utilizing a „spin-flip“ metal complex, and demonstrating a method to generate more energy carriers than incident photons, breaking the 100% quantum yield barrier. This could change how we store energy more effectively in the future.

For the thermodynamically inclined: A single photon can displace a single electron, and the efficiency of that process sets the 100% limit. However, high energy photons can be split into two lower-energy photons, each of which can knock off an electron. Energy remains conserved.

Creative use of percentages. Makes for good headlines. 100 photons release 130 excitons is interesting enough but doesn’t imply magical free energy.
