Nanotechnology breakthrough enables conversion of infrared light to energy

Capturing infrared light for solar cell applications.


Invisible infrared light accounts for half of all solar radiation on the Earth’s surface, yet ordinary solar energy systems have limited ability in converting it to power. A breakthrough in research at KTH could change that.

A research team led by Hans Ågren, professor in at KTH Royal Institute of Technology, has developed a film that can be applied on top of ordinary , which would enable them to use in energy conversion and increase efficiency by 10 percent or more.

“We have achieved a 10 percent increase in efficiency without yet optimizing the technology,” Ågren says. “With a little more work, we estimate that a 20 to 25 percent increase in efficiency could be achieved.”
