Nanoshells trap light for more efficient solar panels
Scientists at Stanford are hard at work trying to improve the efficiency and durability of solar panels -- two key factors that have kept the Sun from becoming a more popular source of energy. Their latest effort involves nanocrystalline-silicon, a material that has proven resilient and highly conductive, but not very good at absorbing light. Their solution, nanoshells -- hollowed out spheres of silicon that trap and recirculate light much like a whispering gallery does sound. Balls of the crystalline material are dipped in silicon, then hydrofluoric acid is used to eat way the center of the sphere, leaving a path for light to enter. The shells trap the light, allowing more of it to be absorbed, and also reduces the effect of non-optimal angles on energy production. Hit up the source for a few more details.
Arman Ahnood teases OLED display with solar cells, idealizes the self-sustaining smartphone
Plenty of effort is going into improving smartphone battery life, but only a few individuals are delving into radical realms to achieve the goal. Take for example, Arman Ahnood, a researcher at the London Centre for Nanotechnology, whose latest prototype uses solar cells to capture wasted energy from OLEDs. Similar to Wysips (which uses only ambient light), and equipment from UCLA (designed for LCDs), each project faces the unenviable task of making the smartphone a self-sustaining piece of gear.Ahnood's handiwork relies on an array of solar cells that surround and sit beneath the phone's display. Currently, the system averages 11 percent efficiency in its energy capture, with a peak efficiency of 18 percent. Naturally, there are gains to be made. Of the light generated from OLEDs, Ahnood approximates that only 36 percent is actually projected outward. Critically speaking, this also suggests that similar power savings could be achieved with dimmer, more efficient displays, but we'll let that slide. As it stands, Ahnood's system is able to generate approximately five milliwatts of additional power, given a screen size of 3.7-inches. It's hardly sustainable, but if the creation lets us squeeze in a few more text messages on Friday night, we'll take it.
Powerskin's SolarCharge still believes in the sun
Remember when Nokia poo-poohed the idea of solar charging as a viable way to keep a smartphone juiced? It seems that no-one told XPal Power, since its PowerSkin brand has just launched a new photovoltaic kit as part of its 2012 lineup here at CES: SolarCharge is a silicone-wrapped brick with a solar panel on one end that'll charge most devices via a microUSB port. The 1000mAh battery tucked inside is rated to pony up around 350 minutes of talk time for your average smartphone. It'll set you back $70 when it arrives in February. KeyCharge attaches to your keychain and can offer a quick boost 90 minutes of additional time on its 750mAh battery, again via its microUSB port. It'll cost a more modest $25 and will be available to order at the same time Come with us, and you'll be, in a world of pure press releases, after the break.
Inhabitat's Week in Green: 2012 Detroit Auto Show, 3D-printed geometric kite and the world's largest battery
Each week our friends at Inhabitat recap the week's most interesting green developments and clean tech news for us -- it's the Week in Green. Green transportation kicks into high gear this week with the launch of the 2012 Detroit Auto Show -- and Inhabitat is set to bring you breaking coverage of this year's event! So far we've taken a look at 6 green cars to watch at NAIAS 2012 -- including Lexus' sexy LF-LC hybrid sports car -- Volkswagen's Beetle-inspired electric concept car, and Smart's For-US super-compact electric pickup truck.

SolarKindle cover basks in the sun's rays, charges for days and days
Direct sunlight and Amazon's Kindle have always gone hand in hand -- you simply can't read E-Ink without a strong light source. So, it would make sense to pair that lighting requirement with a solar panel, pack it into a convenient case, toss in a reading lamp and give readers the gift of effortlessly extended battery life -- which is exactly what SolarFocus intends to do. Scheduled to be shown off at this week's CES, the company's SolarKindle adds three months of unplugged use, in addition to 50 hours for its included LED lamp. And unlike most innovations that take their sweet time getting to market, this cover's slated for a January 15th bow, priced at $80. Take that paperbacks.
Onyx develops 330-watt 'plug-n-play' solar panel with built-in AC outlet
Onyx's new 330-watt solar panel isn't the first to offer a "plug-n-play" solution for getting power to your gadgets, but it may be the first to include a standard US power outlet, and enough output to juice up a computer, light or any other appliance (within reason) through its built-in micro inverter. "You can literally point the panel at the sun and plug an extension cord directly into the panel for immediate power," according to the Onyx PR, which you'll find in full just past the break.
Google's letting it shine as it nears $1 billion investment in solar energy
Google's feeling charitable this holiday and has pumped $94 million into a Californian solar-energy project. The photovoltaic power plant (which is a posh way of saying "lots of solar panels in the Sacramento desert valley") currently being built by Recurrent Energy will generate 88MW, enough juice for 13,000 homes. Additional investment is coming from equity fund KKR, who has already sold the first 20 years of energy to the Sacramento Municipal Utility District. It brings the search giant's investment in clean energy projects to $915 million -- with the company expected to cross the billion dollar mark some time next year, when we hope it'll get a nice loyalty bonus from Mother Nature.
Scientists create first solar cell with over 100 percent quantum efficiency
Researchers over at the National Renewable Energy Lab have reportedly made the first solar cell with an external quantum efficiency over 100 percent. Quantum efficiency relates to the number of electrons-per-second flowing in a solar cell circuit, divided by the number of photons from the energy entering. The NREL team recorded an efficiency topping out at 114 percent, by creating the first working multiple exciton generation (MEG) cell. Using MEG, a single high energy photon can produce more than one electron-hole pair per absorbed photon. The extra efficiency comes from quantum dots 'harvesting' energy that would otherwise be lost as heat. The cell itself uses anti-reflection coating on a transparent conductor, layered with zinc oxide, lead selenide, and gold. NREL scientist Arthur J. Nozik predicted as far back as 2001 that MEG would do the job, but it's taken until now for the concept to leap over from theory. The hope is, of course, that this will lead to more competitively priced solar power, fueling the transport of the future.
Cheap electronic skin edges us closer to cyberpunk future
Researchers working for the Department of Energy's Berkeley Lab have figured out how to create relatively inexpensive "electronic skin" comprising carbon nanotubes enriched with semiconductors. Their process involves an enriched single walled carbon nanotube (SWNT) solution embedded in a honeycomb pattern of hexagonal holes to make it more flexible and stretchable - it's so limber, they wrapped it around a baseball, as you can see in the photo above. Combined with inkjet printing of electrical contacts, the technology paves the way for making flexible, wearable computers and a host of other cool things that William Gibson and other cyberpunk authors thought of back in the 1980s: smart bandages, flexible solar cells and electronic skin that can sense touch. Bring on the Zeiss eye implants and neural interface jacks!

Apple solar patent wants a sunny display light for your Sunny (De)light
Let's begin with the usual disclaimer: Apple patent applications do not mean the outlandish technology will be arriving in the next iPhone, just that someone in a Cupertino basement cooked it up during a marathon "imagining" session (possibly while enjoying a cool glass of purple stuff). The company's latest drawings-and-charts masterpiece concerns the construction and placement of photovoltaic cells and, more importantly, using the sun's energy to illuminate a display. By using a mirror pointed at the sky, you could reflect some rays toward your screen to supplement an LED backlight, or by turning the top lid of your Macbook into a solar panel. Although we can see one minor drawback in using solar powered backlighting -- if you have to point your display toward the sun, you're gonna need some powerful shades.
GE's new factory will push out one solar panel every ten seconds
General Electric is sending its troops to Colorado to conquer the thin film solar panel business. The 38th state will play home to a new facility that leverages the supermodel-thin panel know-how of PrimeStar Solar, which GE scooped up back in 2008. In traditional solar panels, sand is refined into silicon ingots, sliced wafers of which are then placed in a frame. The thin film process eliminates this, sandwiching layers of semiconductors between panes of glass -- saving time, money and, most importantly, energy. The factory will open ahead of schedule in 2012 and is reportedly capable of producing a new panel every ten seconds. You can learn all of that and more in the press release we've got for you after the break.
MIT researchers suggest graphene could be used to build a better camera sensor
As you may have noticed from the pace of research over the past few years, graphene is promising to make a whole lot of things a whole lot better. Now, it seems, you can also add camera sensors to the list. A team of MIT researchers recently discovered that graphene can serve as a photodetector over a "very wide energy range," and that it works particularly well in infrared light, where other types of detectors often come up short. That, the researchers say, could open to the door to everything from better nightvision systems to more advanced detectors for astronomical telescopes -- not to mention more inexpensive camera sensors in general, since graphene is cheap to work with. What's more, the researchers also suggest that those same light-detecting abilities could make graphene a good material for collecting solar energy, although they note that there's still much more research needed to determine if it's truly an efficient means of generating energy.
Murata Tactile Controller TV remote hands-on (video)
What's that, you're not into changing the channel with that boring old remote, or even with your voice? Murata's ground-up Tactile Controller brings a real twist to every couch potato's favorite gadget. Quite literally. The company's prototype remote uses touch-pressure pads and pyroelectricity to analyze the position of a piezoelectric film. In English: a plastic film produces tiny amounts of electricity at various voltages (output as data) when it's forced into a variety of positions, letting you change the channel simply by twisting the controller in either direction, or flexing to adjust volume. The model we saw was a plastic sandwich of sorts, and also included four solar cells, capable of producing one milliwatt of electricity -- just enough to power the device. We put the controller through its paces at the company's CEATEC booth, adjusting a TV's volume and channel up and down, and, well, up and down, since that's just about all you can do with the thing. The model we saw only supported five twist positions and four bending positions in each direction, so it could theoretically adjust those two basic settings more quickly based on how much pressure you put on the film, but realistically can't do much beyond that. The Tactile Controller on display here is more of a proof of concept of sorts -- with the concept being the plastic film technology itself, and not the battery-free remote control, which the company decided would be the most visual application for testing its new film, though not necessarily the most practical. Understandably, Murata doesn't have any plans to release the remote that we saw today, but you can jump past this to see us do the twist.%Gallery-135771%
