Could Nanotech “Coaxial Cable” Increase Solar Cell Efficiency?

From NewScientistTech – Researchers at Boston College have developed cables 300 nanometers in diameter that can transmit visible light. In case you were wondering, 300 nanometers is smaller than the shortest visible wavelength and is invisible to the human eye. Like a regular coaxial cable, this cable consists of 3 parts – a carbon nanotube in the middle, a film of aluminum oxide surrounding the carbon nanotube, and an outside layer of chromium or aluminum. The scientists working on this are anticipating a wide range of applications, including quantum computers and artificial retinas. One of the first applications being targeted is to “increase the efficiency of energy conversion in solar cells by tightly packing together arrays of nano-coax filled with photovoltaic material rather than aluminium oxide.”
