Nano structures are the thinnest light absorbers ever.
Stanford University researchers say that their nanosize structures are capable of absorbing almost 100 percent of visible light from specific wavelengths, while remaining thousands of times thinner than a sheet of paper.
Much like a guitarist tunes a guitar string to create a different frequency sound, the team say that their ultrathin wafers can be tuned to absorb different wavelengths of light by varying the thickness of the layers of gold nanodots which are used to create the wafers.

The team believes the light-absorbers have the potential to significantly enhance the efficiency of solar cells. The small size of the structure as a whole forces energy charge carriers closer to one another, meaning it won’t take as long for the charge carriers to be collected and stimulate electrical current production. As the structures require less material, they could also make solar cell technology more affordable.
