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."

A 10 percent increase in efficiency is huge. To read more, click here.
