Archmage of ProcrastinationSolar cells just passed the Shockley-Queisser limit (solar cells can only utilize about 1/3 of incoming sunlight)
Under normal conditions, each photon produces only one spin-singlet exciton after excitation. With SF (singlet fission), this single exciton can split into two lower-energy spin-triplet excitons, which could effectively double the available energy.

Solar cells just did the “impossible” with this 130% breakthrough
A new solar breakthrough may overcome a long-standing efficiency barrier. Researchers used a “spin-flip” metal complex to capture and multiply energy from sunlight through singlet fission. The result reached about 130% efficiency, meaning more energy carriers were produced than photons absorbed. This could lead to much more powerful solar panels in the future.
