Researchers at Kyushu University in Japan have developed a technology that pushes the energy conversion efficiency of solar cells to 130% using a molybdenum-based 'spin-flip' metal complex. This breakthrough has the potential to significantly increase the amount of usable energy generated from sunlight, surpassing the traditional limits of solar cell efficiency.
Researchers at Kyushu University in Japan have made a breakthrough in solar cell technology. They used a molybdenum-based 'spin-flip' metal complex paired with a singlet fission material to generate more usable energy carriers than incoming photons. This process, called singlet fission, allows a single high-energy photon to result in two lower-energy excitons. The team's approach has the potential to double the number of usable charge carriers. The traditional limit of solar cell efficiency is around 33%, but this new technology has achieved an efficiency of 130%. This breakthrough could significantly increase the amount of usable energy generated from sunlight.
