Scientists Just Broke the Solar Power Limit Everyone Thought Was Absolute Solar energy is widely seen as a key tool in reducing reliance on fossil fuels and slowing climate change. The Sun delivers a vast amount of energy to Earth every second, but today’s solar cells can only capture a small portion of it. This limitation comes from a so-called “physical ceiling” that has long been considered unavoidable. Breakthrough Spin-Flip Technology Boosts Solar Efficiency In a study published today (March 25) in the Journal of the American Chemical Society, researchers from Kyushu University in Japan, working with collaborators at Johannes Gutenberg University (JGU) Mainz in Germany, introduced a new approach to overcome this barrier. They used a molybdenum-based metal complex known as a “spin-flip” emitter to capture extra energy through singlet fission (SF), often described as a “dream technology” for improving light conversion. This method achieved an energy conversion efficiency of about 130%, exceeding the traditional 100% limit and pointing toward more powerful future solar cells. Source:SciTechDaily @EverythingScience
