Artificial moth eyes enhance the performance of silicon solar cells

Mimicking the texture found on the highly antireflective surfaces of the compound eyes of moths, researchers use block copolymer self assembly to produce precise and tunable nanotextured designs in the range of about 20 nm across macroscopic silicon solar cells. This nanoscale texturing imparts broadband antireflection properties and significantly enhances performance compared with typical antireflection coatings.

Nanocomposite window materials can control light and energy

Researchers are one step closer to delivering smart windows with a new level of energy efficiency, engineering materials that allow windows to reveal light without transferring heat and, conversely, to block light while allowing heat transmission.

New molecular butterflies help advance energy research

Imagine a family of butterflies fluttering around in a controlled lab space. Except, the butterflies aren't really butterflies. They are molecules designed and produced as new functional materials that have a wide range of applications from molecular sensors to light-controlling devices.

Boosting gas mileage with graphene

Researchers report the development of a material that could convert engine heat that's otherwise wasted into electrical energy to help keep a car running - and reduce the need for fuels.

The virtual laboratory

Different length and time scale domains provide different levels of information, but little is currently known about how these levels of information are connected. A long-term programme aims to connect the scales, relating the behaviour of atoms and molecules to tangible properties at the macroscale.

An easy, scalable and direct method for synthesizing graphene in silicon microelectronics

Researchers have developed an easy and microelectronics-compatible method to grow graphene and have successfully synthesized wafer-scale (four inches in diameter), high-quality, multi-layer graphene on silicon substrates. The method is based on an ion implantation technique, a process in which ions are accelerated under an electrical field and smashed into a semiconductor.
