Leading Atomic Layer Deposition (ALD) systems manufacturer Picosun Oy, Finland, takes part in an EU funded research project aiming at dramatically increasing the efficiency of solar cells.
A single semiconductor laser chip with world-record wavelength tuning range of 200 nanometers - from 500 to 700 nanometers - has been demonstrated by a research team led by Cun-Zheng Ning, a professor in the Department of Electrical Engineering in the Ira A. Fulton School of Engineering at Arizona State University.
"These new pictures are instantaneous snap-shots of energy being transported between electrons across a protein. Remarkably, the pictures go further in unravelling the complex way the electrons interact. This gives us something akin to a fingerprint for electronic couplings," says Dr Ian Mercer from the School of Physics at University College Dublin, the lead author of the new study, who is a visiting researcher at Imperial College London.
Future telescopes, with mirrors half the size of a football field, will need special components to deal with the light they collect. Astronomers are turning to photonic devices that guide and manipulate light inside specially-designed materials. The greatest potential, which is described in the latest issue of Optics Express, the Optical Society's (OSA) open-access journal, may lie in a laser-based technique that carves out micron-sized light pathways in three dimensions.
The discovery that butterfly wings have scales that act as tiny solar collectors has led scientists in China and Japan to design a more efficient solar cell that could be used for powering homes, businesses, and other applications in the future. Their study appeared in the Jan. 13 issue of ACS' Chemistry of Materials, a bi-weekly journal.
"Knowledge of the sizes and shapes of asteroids is crucial to understanding how, in the early days of our Solar System, dust and pebbles collected together to form larger bodies and how collisions and re-accumulation have since modified them," says Marco Delbo from the Observatoire de la Côte d'Azur, France, who led the study.
Someday, moving a large, flat-screen TV across the country might be as simple as taking it off the wall, rolling it up and sliding it into a study tube. That's the vision of researchers Christopher Ober and George Malliaras at Cornell University, and Andrew Holmes at the University of Melbourne, Australia, who are fabricating organic semiconducting materials with a little help from supercritical carbon dioxide, or CO2.
There will be setbacks but according to a just-published report from NanoMarkets, an industry analysis firm based here, CIGS -- a photovoltaic material technology made of copper-indium-gallium-selenium -- will fulfill its potential as the wonder child of the thin-film photovoltaic (TFPV) materials business.
The Canadians are gathering at Photonics West 2009 in San Jose, CA with OCRI representatives to build on what a new industry report says is a shining success. In its survey entitled "Illuminating a World of Opportunity," the Canadian Photonics Consortium states Canada has 370 photonics companies employing some 20,000 people who collectively generate close to $4.5 billion annually, with approximately 85% from exports including 50% to the U.S.
The Spanish PV market grew by more than 2661 Megawatts of new installed power in 2008. As a result, the global PV market has grown by around 5600 Megawatts. This enormous 100% increase compared with the 2007 figure explains part of the scarcity and high module prices in 2008. But, with a cap of 500 MW in 2009, it also means that the Spanish market will decrease in size by at least 80% (or more than 2100 MW) this year.
