The new process uses light to do photochemistry instead of the traditional method of using heat to do chemistry.

Scientists from Emory University are opening yet another door to renewable energy efforts. Their new way of performing light-driven reactions based on plasmon—the motion of free electrons that strongly absorb and scatter light—is said to be much more effective than previous processes.
“We’ve discovered a new and unexpected way to use plasmonic metal that holds potential for use in solar energy conversion,” says Tim Lian, professor of physical chemistry at Emory University and the lead author of the research. “We’ve shown that we can harvest the high energy electrons excited by light in plasmon and then use this energy to do chemistry.”
To get a better understanding of surface plasmonic, just think of how a cathedral’s stained glass windows absorb and shatter light.
Researchers involved in this study believe their plasmonic centered process could apply to efforts in electronics and renewable energy. Using plasmon could potentially make light-driven charge transfer for solar energy conversion much more efficient.
