Sun's Rays into a Nanowire (IMAGE) University of Copenhagen - Niels Bohr Institute Caption The figure shows that the sun's rays are drawn into a nanowire, which stands on a substrate. At a given wavelength the sunlight is concentrated up to 15 times. Consequently, there is great potential in using nanowires in the development of future solar cells.
