Silicon is the second most abundant element on Earth, and the ability to manufacture supercapacitors from it along with the integrated circuits that it powers could have very interesting repercussions all across the electronics industry.

According to the researchers, it should be possible to build cheap silicon supercapacitors out of the excess silicon contained inside many electronic devices. One such example are solar cells: supercapacitors built out of the silicon in the back side of solar cells could store energy during the day and gradually release it into the energy grid during the hours of peak consumption.

The advance is described in an open-access paper in the journal Nature Scientific Reports.
