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.

When choosing materials to make something, trade-offs need to be made between a host of properties, such as thickness, stiffness and weight. Depending on the application in question, finding just the right balance is the difference between success and failure

Scientists developed specially coated nanometer-sized vehicles that can be actively moved through dense tissue like the vitreous of the eye. So far, the transport of nano-vehicles has only been demonstrated in model systems or biological fluids, but not in real tissue. The work was published in the journal Science Advances and constitutes one step further towards nanorobots becoming minimally-invasive tools for precisely delivering medicine to where it is needed.
Researchers of the “Micro, Nano and Molecular Systems” Lab at the Max Planck Institute for Intelligent Systems in Stuttgart, together with an international...
