Laser pulse doubles black silicon’s solar efficiency
Dec 1, 2012 — A solar material that takes advantage of a spectrum totally unused by standard cells could be the key to more efficient photovoltaics, now that a team in Germany has successfully doubled its efficiency. Solar cells convert three-quarters of the energy in the sun’s spectrum into electricity, but about a quarter of its spectrum – the infrared – is lost in standard solar cells. Black silicon cells, however, are specifically designed to absorb nearly all of the sunlight that hit...

Quantum dot ink will make lasers printable
CLAYTON SOUTH and MELBOURNE, Australia, & PADUA, Italy – Printing techniques that already have been incorporated into solar cell manufacturing could prove useful for the production of lasers and other emitting optoelectronic devices, according to researchers from Australia and Italy. Quantum dots are...
"Totally new physics" yields first germanium laser
BOSTON – It’s the very first germanium laser capable of emitting wavelengths useful for optical communications. It’s also the first operable at room temperature. And this new laser not only holds promise for optical computing but also proves that...
