Researchers have used magnetic fields to reveal the mystery of how light particles split. Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light photons into small chunks.
Scientists are closer to giving the next generation of solar cells a powerful boost by integrating a process that could make the technology more efficient by breaking particles of light -- photons -- into small chunks., researchers unravel the scientific understanding of what happens when light particles split -- a process called singlet fission -- and its underlying workings.
"But as part of this process, a lot of this light is lost as heat. Which is why solar panels don't run at full efficiency." "The highest efficiency was set earlier this year by our industrial collaborator, LONGi. They demonstrated a 27.3 per cent efficient silicon solar cell," he says.Prof. Schmidt says scientists were still trying to understand how the molecular process of singlet fission worked. Specifically, how does one become two? He says the process is complex and detailed.Working smarter, not harder
The team used a single wavelength laser to excite the singlet fission material. Then they used an electromagnet to apply magnetic fields -- which reduced the speed of the singlet fission process, making it easier to observe.
