New Material Absorbs Light Completely And Generates Electricity


A partnership between Duke University and Boston College turned out to be very beneficial for the science world, as they obtained a metamaterial that absorbs all the light it gets (no, it doesn’t make things invisible), thus capable of generating more energy even than the solar cells.

It can’t be used as a camouflage, as it’s simply black, but scientists surely have other applications to put it to work into. The metallic material absorbs both the magnetic and electrical properties of electromagnetic waves over a certain frequency range, thus turning the light into heat. And as many of us already know, there are just a few sources of energy more efficient than heat.

The fact that science still finds new ways to produce electricity is laudable, but in the same time, it shows us that we have much to learn and that many unexploited areas of science are waiting to be unveiled. Meanwhile, it will surely be interesting to see how this discovery will evolve.
