One energy sources considered the cleanest, also that does not require a charge for this to work, is of natural origin, sunlight, and to be exploited to the fullest, various scientific communities are constantly working.
On this occasion, presented the work done by the Berkeley National Laboratory, in conjunction with the University of California at Berkley, those developing an innovation in the field of nano-pillars, a technology that allows to absorb sunlight either similar or better than conventional solar cells.
Firstly, the main advantage is given in dimensions, since it is nanotechnology works at very small sizes, offering equal performance and up to the possibility of having greater benefits, since for reasons of size, unless needed half of the semiconductor material used for the a solar panel construction.
As reported, with a height of only two microns, these nanopilares have managed to absorb the magnetic spectrum range among the 300 and 900 nanometers, with an efficiency of 99%, without using light anti-reflexivas decks.
The application on a large scale of this technology will allow renewed form of photovoltaic, solar energy and significantly reduce the necessary spaces for a lot of energy.
