New Solar Cell Sets World Efficiency Record

asoduk writes to tell us that a new world record has been set for the most efficient photovoltaic device. Topping the scale at 40.8% efficiency, the new solar cell differs significantly from the previous record holder. "Instead of using a germanium wafer as the bottom junction of the device, the new design uses compositions of gallium indium phosphide and gallium indium arsenide to split the solar spectrum into three equal parts that are absorbed by each of the cell's three junctions for higher potential efficiencies. This is accomplished by growing the solar cell on a gallium arsenide wafer, flipping it over, then removing the wafer. The resulting device is extremely thin and light and represents a new class of solar cells with advantages in performance, design, operation and cost.

7th-Grader Designs Three Dimensional Solar Cell

Hugh Pickens writes "12-year-old William Yuan's invention of a highly-efficient, three-dimensional nanotube solar cell for visible and ultraviolet light has won him an award and a $25,000 scholarship from the Davidson Institute for Talent Development. 'Current solar cells are flat and can only absorb visible light'" Yuan said. 'I came up with an innovative solar cell that absorbs both visible and UV light. My project focused on finding the optimum solar cell to further increase the light absorption and efficiency and design a nanotube for light-electricity conversion efficiency.' Solar panels with his 3D cells would provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells.

New Optics For Improved Solar Power Generators

A few years ago, the U.S. Defense Advanced Research Projects Agency (DARPA) launched its Very High Efficiency Solar Cell (VHESC) program. DARPA challenged the industry and the research community to make solar cells more efficient -- as measured by how well a solar cell converts the light it absorbs into electrical energy.

New Eye on the Outer Solar System Launches Successfully

There's a new spacecraft in Earth orbit, with a really "far out" mission: to map the outer solar system. NASA's Interstellar Boundary Explorer mission, or IBEX launched successfully from the Kwajalein Atoll in the Pacific Ocean at 1:47 p.m. EDT, Sunday, from an Orbital Sciences Pegasus XL launch vehicle. IBEX will be the first spacecraft to image and map dynamic interactions taking place in the outer solar system. The two Voyager probes sent back a limited amount of information about the region of space where our solar system ends and interstellar space begins. But beyond that, not much is known about this area. The region is about three times further from the sun than the orbit of planet Pluto. "No one has seen an image of the interaction at the edge of our solar system where the solar wind collides with interstellar space," said IBEX Pr

Solar Power Game-Changer: "Near Perfect" Absorption of Sunlight, From All Angles

Researchers at Rensselaer Polytechnic Institute have discovered and demonstrated a new method for overcoming two major hurdles facing solar energy. By developing a new antireflective coating that boosts the amount of sunlight captured by solar panels and allows those panels to absorb the entire solar spectrum from nearly any angle, the research team has moved academia and industry closer to realizing high-efficiency, cost-effective solar power.

Solar Cycle 24 Sunspots Finally Say "Hello!"

After an extended period of calm for Solar Cycle 24, a cluster of sunspots have appeared on the disk of the Sun. Although we have observed sunspots since the beginning of this new solar cycle (which officially began on January 4th, 2008 with the observation of a high-latitude sunspot pair), this is the first time for many months "new" Cycle 24 sunspots have shown themselves. Before today, the sunspots (including occasional flares and coronal mass ejections) belonged to the previous cycle (Cycle 23). It would appear the spots have evolved into a cluster in a high-latitude location with the magnetic polarity consistent with this new cycle. But does this mean we can expect an increase in solar activity after this pretty dull period of "blank" solar disk observations? Your guess is as good as mine…

Optomec Reports New Orders for Aerosol Jet Solar Lab Printing System: Solar Manufacturers and Material Developers Look to Aerosol Jet Printing for Imp

Optomec announced today that the company has received significant orders for its Aerosol Jet Solar Lab system since its introduction earlier this year. The Solar Lab system is a process development platform that enables customers to define and develop improved collector line patterns for current and next generation high-efficiency solar cells by printing much finer collector lines than is currently possible with traditional screen-printing methods. These narrower, high integrity collector lines have higher conductivity and a lower shadowing effect, thereby increasing photovoltaic cell efficiency (>1%). Additionally, the non-contact deposition process used by Aerosol Jet is ideal for printing on thinner wafers. The system is commonly used as a precursor before moving to a full production Aerosol Jet print line solution provided in partners

Apple Announces New MacBook, Pro, Air

Steve Jobs just got through announcing new MacBook lines in Cupertino. The MacBook, the Pro, and the Air all got revved. The old line of plastic-body MacBooks drops in price by $100, to $999. The new MacBooks have a metal body and multi-touch trackpad, just like the new Pros. The Pro features two NVidia graphics chips. Quoting Jobs: "With the 9400M, you get 5 hours of battery life, with the 9600M GT you get four hours of battery life. You choose." In summary: "We're building both [MacBook and Pro] in a whole new way. From a slab of aluminum to a notebook. New graphics. New trackpad, the best we've ever built. And LED-backlit displays that are far brighter, instant on, far more environmentally responsible." They are shipping today and should be in stores tomorrow.
