Nanotechnologies which can artificially change the optical properties of materials to allow light to be trapped in solar cells could greatly reduce the cost of solar energy.
Research being carried out by the School of Electronics and Computer Science (ECS) at the University of Southampton is focusing on nanopatterning as the way to design effective solar panels. ‘By drawing features that are much smaller than the wavelength of light, photons can be confused into doing things they normally wouldn’t do,’ says Dr Darren Bagnall, of the School of Electronics and Computer Science. ‘By creating diffractive nanostructured arrays on the surface of solar cells we ensure that optical asymmetries are created that prevent light from escaping the solar cells.’
According to Dr Bagnall the light-trapping technologies could reduce the thickness of semiconductor materials needed in solar panels, and this would directly reduce the cost. The first challenge is to prove that the technology works in practice, the second key challenge will be to develop cost effective ways to produce nanopatterned layers.

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.
This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.
"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...
