“Everything that’s warm gives off some heat”, Sargent said. “So there actually is some power remaining in the infrared spectrum, even when it appears to us to be dark outside”.

The researchers combined specially designed nano-particles called quantum dots with a polymer to make the plastic that can detect energy in the infrared. With further advances, the new plastic “could allow up to 30 percent of the sun’s radiant energy to be harnessed, compared to 6 percent in today’s best plastic solar cells”, said Peter Peumans, a Stanford University electrical engineering professor, who studied the work.

Electrical Sweaters

The new material could make technology truly wireless. Sargent said that the plastic coating could be woven into a shirt or sweater and used to charge an item like a cell phone.

“A sweater is already absorbing all sorts of light both in the infrared and the visible”, said Sargent. “Instead of just turning that into heat, as it currently does, imagine if it were to turn that into electricity”.

Other possibilities include energy-saving plastic sheeting that could be spread on a rooftop to supply heating needs, or solar cell window coating that could let in enough infrared light to power home appliances.
