ECN Heads Consortium to Develop a-Si Plastic Thin Films: Targets 7.5% Module Efficiencies
Posted February 22, 2010 on PV-tech.org

Development of a SI Plastic Thin FilmA program that started at the beginning of the year and headed by Energy Research Centre of the Netherlands (ECN), hopes to develop a new amorphous and microcrystalline silicon thin film cell using plastics as the substrate foil. The three-year 'Silicon-Light' programme is subsidized by the European Commission in the framework of the thematic research programme Energy in FP7. The R&D consortium includes EPFL, University of Copenhagen, University of Valencia, JiaoTong University of Shanghai, Umicore and VHF Technologies (Flexcell), the hopeful commercial end-user of the programme. Flexcell is a subsidiary of Q-Cells.

To be able to use low-cost materials such as plastics, the Silicon-Light' programme will develop low process temperatures (typically below 200C), using plasma enhanced chemical vapour deposition (PECVD) processes.

Photovoltaic Breakthroughs Brighten Outlook for Cheap Solar Power: Novel materials might make harvesting sunlight for electricity affordable
By David Biello, Scientific American, February 16, 2010

Enough sunlight bathes Earth's daytime half in an hour to meet all human energy needs for a year. Sadly, there are several problems with meeting human energy demands by tapping such abundant, free solar power-not least of which is the cost of making semiconducting material that can cheaply harvest the power in sunlight. But material improvements from the California Institute of Technology and IBM might just lower the cost of solar power.

Graduate student Michael Kelzenberg and other materials scientists at Caltech employed vertical crystals of silicon-microwires, like "blades of grass," Kelzenberg says-to capture as much as 85 percent of the full spectrum of incoming sunlight, the researchers report in the February 14 Nature Materials. (Scientific American is part of Nature Publishing Group.) Their efficiency is almost as good as that of traditional silicon wafers, yet they require just one percent of the silicon in such wafers.

"With one one-hundredth of the material, we've gotten it to absorb 96 percent of the peak visible light," Kelzenberg says. "There's lots of reasons to believe this could be scaled to make thin-film solar cells."

Gecko's Lessons Transfer Well: Dry Printing of Nanotube Patterns to Any Surface Could Revolutionize Microelectronics
From ScienceDaily - January 31, 2010
Nanotubes

Watch a gecko walk up a wall. It defies gravity as it sticks to the surface no matter how smooth it appears to be.

What's happening isn't magic. The gecko stays put because of the electrical attraction -- the van der Waals force -- between millions of microscopic hairs on its feet and the surface.


The principle applies to new research at Rice University reported this week in the online version of the journal ACS Nano. But in this case, the hairs figuratively come off the gecko and plant themselves on the wall.

Rice graduate student Cary Pint has come up with a way to transfer forests of strongly aligned, single-walled carbon nanotubes (SWNTs) from one surface to another -- any surface -- in a matter of minutes. The template used to grow the nanotubes, with its catalyst particles still intact, can be used repeatedly to grow more nanotubes, almost like inking a rubber stamp.

Pint is primary author of the research paper, which also details a way to quickly and easily determine the range of diameters in a batch of nanotubes grown through chemical vapor deposition (CVD). Common spectroscopic techniques are poor at seeing tubes bigger than two nanometers in diameter -- or most of the nanotubes in the CVD "supergrowth" process.

Super-Thin Films that Harvest Energy from Motion
Posted February 24, 2010 on www.azonano.com

Scientists are reporting an advance toward scavenging energy fromSuper Thin Fils that Harvest Energy from Motion walking, breathing, and other natural body movements to power electronic devices like cell phones and heart pacemakers.

In a study in ACS' monthly journal, Nano Letters, they describe development of flexible, biocompatible rubber films for use in implantable or wearable energy harvesting systems. The material could be used, for instance, to harvest energy from the motion of the lungs during breathing and use it to run pacemakers without the need for batteries that must be surgically replaced every few years.

Michael McAlpine and colleagues point out that popular hand-held consumer electronic devices are using smaller and smaller amounts of electricity. That opens the possibility of supplementing battery power with electricity harvested from body movements. So-called "piezoelectric" materials are the obvious candidates, since they generate electricity when flexed or subjected to pressure. However, manufacturing piezoelectric materials requires temperatures of more than 1,000 degrees F., making it difficult to combine them with rubber.
 


Crystal Growth Points to Defect-Free Thin Films
Alexander E. Braun, Senior Editor -- Semiconductor International, 2/1/2010

Cornell University (Ithaca, N.Y.) scientists are studying the challenges that arise from the fact that to make semiconductor thin films, layers of atoms must be grown in neat, crystalline sheets. While some materials usually grow smooth crystals, others develop bumps and defects, leading researchers to seek insights into how atoms arrange themselves into thin films.

Physics ProCornell Studying   Colloidal Crystalfessor Itai Cohen, who leads the research, indicated that the effort resulted from his colloidal suspension work. "Colloids are a good model system for investigating atomic-scale phenomena," he said. "The particles are small enough to behave like atoms but still large enough to be observed under a microscope and manipulated with optical tweezers. They're ideal because you set up the experiment and nature does the calculations."

Using an optical microscope, the Cornell scientists see exactly what these atom-mimicking particles - micron-sized silica particles suspended in fluid - do as they crystallize. By manipulating them individually they tested conditions that lead to smooth crystal growth, and discovered that the random darting motion of the particles is a key factor affecting how crystals grow.

Template Engineering Demonstrates Possibilities of New Superconducting Material

By Sandra Knisely, University of Wisconsin-Madison News,

Feb. 28, 2010


A breakthrough approach by University of Wisconsin-Madison researchers and their collaborators in fabricating thin films of a new superconducting material has yielded promising results: The material has a current-carrying potential 500 times that of previous experiments, making it significant for a variety of practical applications.


The new approach and results appeared online in the journal Nature Materials today (Feb. 28) and illustrate a significant step forward in superconductor research.


"We've shown how to grow quality, single-crystal thin films of this class of materials, so people can study the fundamental properties and limits of them," says Chang-Beom Eom, a UW-Madison professor of materials science and engineering, who led the collaboration between UW-Madison and teams from the National High Magnetic Field Laboratory and the University of Michigan.

LASER MARKETPLACE 2010: How wide is the chasm?

Laser Focus World, Jan 1, 2010 - Gail Overton, Stephen G. Anderson, David A. Belforte, and Tom Hausken

The Laser Focus World 2010 annual review and forecast of the laser marketplace is conducted in conjunction with Strategies Unlimited (Mountain View, CA; a PennWell company) with additional input from Industrial Laser Solutions magazine. This article covers the global market for both nondiode and diode lasers.

The economiLaser Focus World Graphc indicators were so dire in the latter part of 2008 that Laser Focus World-anticipating laser sales to remain flat or decrease as much as 20%, depending on the market sector-forecast an overall 11.3% drop in the worldwide laser markets to $6.32 billion (see www.laserfocusworld.com/articles/349353). But by early 2009, it was obvious that the chasm would be even deeper. According to our annual survey, actual laser sales for 2009 were $5.32 billion-a 24.1% drop from the $7.01 billion for 2008, setting sales back to 2003 levels. And if Main Street is any indication (forget the "subsidized" rally on Wall Street), this deep chasm is also wide. Even though the U.S. unemployment rate dropped to 10.0% in November 2009 from its 10.2% high (a jobless recovery), many economists predict that it could be three years before jobs return and sales improve to pre-2008 levels.

Fire-Rated Glass Forecast

Katy Devlin, Glass Magazine, January 7, 2010


Safti First, San Francisco, supplied its SuperLite II-XL 120 in GPX Framing for Ohio's Cleveland Clinic.

Nonresidential construction spending is expected to fall 5 percent in 2010, following a 5.7 percent loss in 2009, and isn't expected to rebound until 2011, according to Jim Haughey, chief economist, Reed Construction Data, Norcross, Ga. Despite the grim forecast, representatives from fire-rated glazing suppliers remain optimistic. The market segment is partly insulated from the downturn thanks to code requirements, building trends and increased funding for some public projects, they say.


"Although we areGlass Magazine currently experiencing a very soft market in the commercial construction industry, demand for non-wired fire-rated glazing products continues to grow," says Dan Poling, sales manager, fire rated glass products, Schott North America Inc., Elmsford, N.Y. Poling attributes the growth to adoption of International Building Codes nationwide.

Photonics Applied: Optical biomimetics emerge from a deep, dark past

Andrew Parker, Laser Focus World, January 1, 2010


"In the country of the blind, the one-eyed man is king." This famous dictum from H. G. Wells tells us something that may seem self-evident: sight matters. But imagine for a moment that the country of the blind is in fact the whole world, 521 million years ago. It's a world in which life is primitive and aimless, and evolution slow and painstaking.

 

Optical BiomimeticsThen something remarkable happens. Over the next million years,Biomimetics the process of evolution kicks into overdrive. For the first time, animals evolve hard external parts. Both hunters and prey develop armaments and defenses. So in this short space of time-the blink of an eye in geological terms-all animals on Earth, no matter how unrelated, leave their soft skins behind. When I traced back the origin of vision, I found that the first image-forming eye evolved in a predatory animal (one that could have an impact on others) around 521 million years ago, precisely at the beginning of this Big Bang of evolution. Hence vision appears to have lit the fuse for life's explosion.

 

But why is this important to the photonics community? Because with those first hard parts in animals came the first photonic nanostructures on Earth. With the evolution of the eye, the size, shape, color, and behavior of animals were suddenly revealed for the first time. The animal kingdom exploded into life. Color was among their main weapons. And from that moment until today, color on Earth has functioned to provide camouflage and crypsis, as well as warning colors and mating colors to attract the eye...

Heavy Elements: International body dubs element 112 Copernicium

Mitch Jacoby, Chemical and Engineering News, February 26, 2010


The periodic table officially has a new entry.  The International Union of Pure & Applied Chemistry announced its approval last week of the name copernicium and symbol Cn for element 112 (Pure Appl. Chem., DOI: 10.1351/PAC-REC-09-08-20).


The approval follows IUPAC's extensive review of claims made by the GSI Helmholtz Center for Heavy Ion Research, in Darmstadt, Germany, of being the first team to synthesize element 112. GSI's claims date back to 1996. IUPAC's announcement raises to six the total number of elements officially discovered and named by GSI.

GSI team leader Sigurd Hofmann explains that his team's intention in selecting the name for element 112 is "to salute Nicolaus Copernicus, an influential scientist who didn't receive any accolades in his own lifetime, and to highlight the link between astronomy and the field of nuclear chemistry." Copernicus was the 16th-century Polish astronomer who developed the sun-centered model of the solar system-a radical departure from the thinking that prevailed in Copernicus' day.


The Darmstadt researchers have previously been recognized for the discovery of five other elements, which they named bohrium (107), hassium (108), meitnerium (109), darmstadtium (110), and roentgenium (111).

Mechanical Devices Stamped on Plastic

Larry Hardesty, MIT News, February 26, 2010


Microelectromechanical devices - tiny machines with moving parts - are everywhere these days: they monitor air pressure in car tires, register the gestures of video game players, and reflect light onto screens in movie theaters. But they're manufactured the same way computer chips are, in facilities that can cost billions of dollars, and their rigidity makes them hard to wrap around curved surfaces.


Devices Stamped on PlasticMIT researchers have discovered a way to make microelectromechanical devices, or MEMS, by stamping them onto a plastic film. That should significantly reduce their cost, but it also opens up the possibility of large sheets of sensors that could, say, cover the wings of an airplane to gauge their structural integrity. The printed MEMS are also flexible, so they could be used to make sensors with irregular shapes. And since the stamping process dispenses with the harsh chemicals and high temperatures ordinarily required for the fabrication of MEMS, it could allow MEMS to incorporate a wider range of materials.

Conventional MEMS are built through a process called photolithography, in which different layers of material are chemically deposited on a substrate - usually a wafer of some semiconducting material - and etched away to form functional patterns. Since a wafer is at most 12 inches across, arranging today's MEMS into large arrays requires cutting them out and bonding them to some other surface.
