TechnologyNew Solid Material Turns Ordinary Sunlight Into Higher-Energy UV LightA Kyushu University team built a stable solid material that fuses two visible photons into one ultraviolet photon — a long-sought breakthrough that could power cleaner air purification and solar chemistry.
ScienceSolar Cells Just Hit 130% Efficiency — Breaking a Long-Standing LimitScientists in Japan and Germany used a molybdenum "spin-flip" emitter to harvest extra energy from sunlight through singlet fission, reaching a quantum yield of about 130% — past the long-standing Shockley-Queisser ceiling.
TechnologyScientists Shatter the Solar Cell Efficiency Ceiling with a 130% Quantum YieldA team from Kyushu University and Johannes Gutenberg University achieved what was long thought impossible — extracting more energy carriers from sunlight than photons absorbed.
