Nanowires have the power to revolutionize solar energy


 

Imagine a solar panel more efficient than today's best solar panels, but using 10 000 times less material. This is what EPFL researchers expect given recent findings on these tiny filaments called nanowires. Solar technology integrating nanowires could capture large quantities of light and produce energy with incredible efficiency at a much lower cost. This technology is possibly the future for powering microchips and the basis for a new generation of solar panels.
Despite their size, nanowires have tremendous potential for energy production. "These nanowires capture much more light than expected," says Anna Fontcuberta i Morral about her research, published on 24 March 2013 in Nature Photonics ("Single-nanowire solar cells beyond the Shockley–Queisser limit").
