Sharp unveils semi-transparent solar panels, lets you see the sun while reaping its benefits

Sharp has announced an unusual photovoltaic panel for the Japanese market that collects energy from the sun while still allowing the light to shine on through. Though it's rated at a lowly 6.8 percent / 98 watt max efficiency, the glass-like properties make it useful as a construction material (as shown in the balcony railing above), with the semi-transparent nature giving occupants privacy, to boot. The energy-producing cells are embedded in a laminated glass structure and an air slot provides a thermal barrier, allowing the panels to also be used as "windows, curtain wall and eaves" according to Sharp's PR. Though the system won't win any potency prizes, it has garnered a design award in Japan, so it won't blight any landscapes. There's no mention of pricing or western availability so far, but you can hit the source for all the technical details.

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.

Inhabitat's Week in Green

Man-made technology is great, but Mother Nature is the greatest inventor of them all -- and scientists are discovering new ways to take advantage of the tools found in nature. Take, for example, a team of researchers from Vanderbilt University who developed a solar cell using the photosynthetic protein found in spinach. In New York, Scape Studio has proposed to use the oyster's natural cleaning ability to help clean up the contaminated waters of the Gowanus Canal. The firm has received funding to create Oyster-tecture, an oyster park at the mouth of the canal where millions of mollusks will "eat" toxins. Meanwhile, the US Forest Service has been deriving cellulose nanocrystals from wood pulp extract to create a material that's stronger than Kevlar and carbon fiber.

Spherical glass lens concentrates sunlight by up to 10,000 times, boosts solar cell efficiency

Eking out more power from solar cells is an ongoing challenge for scientists, and now architect André Broessel has developed a spherical glass energy generator that's said to improve efficiency by 35 percent. Acting as a lens, the rig's large water-filled orb concentrates diffused daylight or moonlight onto a solar cell with the help of optical tracking to harvest electricity. In certain configurations, the apparatus can be used for solar thermal energy generation and even water heating. In addition to the oversized globe, Broessel has cooked up a mobile version of the contraption for domestic use and an array of much smaller ball lenses with dual-axis tracking that offers 40 percent efficiency. These devices aren't the first venture into concentrated photovoltaics, but they are likely among the most visually impressive. If the Barcelona-based architect's vision of the future comes true, you'll be seeing these marbles incorporated into buildings and serving as standalone units. Hit the source links below for the picture spread of prototypes and renders.

IBM alliance sets efficiency record for solar power cells using common materials

IBM alliance sets efficiency record for solar power cells using common materials

There have been more than a few solar power efficiency records set in the past few months, let alone years. What makes IBM, DelSolar, Solar Frontier and Tokyo Ohka Kogyo think they can just waltz in and claim a record of their own? By using more commonplace elements in the periodic table, that's how. The partnership's new photovoltaic cell based on copper, zinc and tin (CZTS for short) can convert light rays to electric power with a 11.1 percent efficiency rate -- still nothing to upset traditional silicon power, but a large 10 percent more efficient than anything else in the class. In its early form, CZTS can already be manufactured through ink printing and could be produced in quantities equivalent to about 500 gigawatts of power per year, or five times more than some of the next-closest alternatives. The group wants to improve CZTS' efficiency over the course of the next several years, ideally reaching the point where it's useful as a truly cheap, ubiquitous source of power. We're looking forward to the day when there's a little slice of solar energy in just about everything, hopefully including a few more hybrid cars and private aircraft.

Researchers create record-breaking solar cell, set bar marginally higher

Solar cell development is typically a small numbers game, and a group of researchers at the University of Toronto have managed to eke out a few more percentage points in efficiency with a new record-breaking cell. Setting a high mark for this type of cell, the team's Colloidal Quantum Dot (CQD) film harvests both visible and non-visible light at seven percent efficiency, a 37 percent increase over the previous record. The breakthrough was achieved by leveraging organic and inorganic chemistry to make sure it had fewer nooks and crannies that don't absorb light. With the advantages of relatively speedy and cheap manufacturing, the technology could help lead the way for mass production of solar cells on flexible substrates. In the meantime, check out the source for the scientific lowdown.

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.

DNP This Week in Green TKTKTK

LED technology shone brighter than the summer sun this week as artist Bruce Munro unveiled plans for his largest lighting installation ever -- a field of thousands of LED flowers that will spring up next year at Australia's Ayers Rock. Best of all, the entire installation will be powered by solar energy! We also saw Rice University flip the switch on its new Epiphany Skyspace -- a green-roofed pavilion that's topped with a brilliant blue canopy of light. If you're still not convinced that LEDs are the future, we recently produced two videos that are sure to show you the light -- check out our interview with five professional lighting designers on today's state of the art LED bulbs and watch as we give Inhabitots editor Julie Seguss a light bulb overhaul that shaves over $400 off her utility bills. And if you're ready to make the switch, check out our guide to 24 gorgeous green lamps that look great with LED bulbs.

This week saw some exciting new developments in the realm of renewable energy. First, a group of scientists in the UK developed a new energy-harvesting device that attaches to the joint between the thigh and shin. The device could be used to power monitors and mobile devices, to name a few possible applications. Meanwhile, scientists from Nanyang Technological University in Singapore have invented a new toilet that turns human waste into electricity while reducing the amount of water needed for flushing by up to 90 percent. That's what we call, win-win!

All-carbon solar cell draws power from near-infrared light, our energy future is literally that much brighter

Fully carbon solar cell can power up from infrared light, our future is literally that much brighter

What's this orange-like patch, you ask? It's a layer of carbon nanotubes on silicon, and it might just be instrumental to getting a lot more power out of solar cells than we're used to. Current solar power largely ignores near-infrared light and wastes about 40 percent of the potential energy it could harness. A mix of carbon nanotubes and buckyballs developed by MIT, however, can catch that near-infrared light without degrading like earlier composites. The all-carbon formula doesn't need to be thickly spread to do its work, and it simply lets visible light through -- it could layer on top of a traditional solar cell to catch many more of the sun's rays. Most of the challenge, as we often see for solar cells, is just a matter of improving the energy conversion rate. Provided the researchers can keep refining the project, we could be looking at a big leap in solar power efficiency with very little extra footprint, something we'd very much like to see on the roof of a hybrid sedan.

Apple breaks ground on second solar farm for North Carolina data center

Last February, Apple came clean about its efforts to clean up the environment, detailing intentions to make its Maiden, NC data facility a greener place. That site, already home to one solar farm, is now set to host a second 20 megawatt photovoltaic array spanning 100 acres, a one-two power punch that'll jointly generate 84 million kWh annually. Combined with the company's in-development biofuel cell plant, scheduled for opening later this year, that theoretic yield should hit the 124 million kWh mark -- an amount sufficient to power nearly 11,000 households -- providing 60 percent of the center's electric demands. Still, that's not enough to adequately keep operations afloat, so for that very necessary, leftover 40 percent, the house that Jobs built plans to purchase similar clean energy from outside local sources. When all is finally up and running smoothly, the southern facility will earn the distinction of "most environmentally sound data center ever built." Or, at least until another well-heeled competitor comes along to contest that title. Now that's a friendly competition we can get behind.

First solar-powered boat to circle the world pulls into home port, contemplates next move

It's been two years since we last heard of the 98-foot-long solar-powered boat, which at the time was gearing up for its big journey around the world. Well, some 19 months and 37,286 miles after setting sail from Monaco, the MS Turanor PlanetSolar has finally made it home. The PlanetSolar broke four Guinness world records along the way, including the all-important "first circumnavigation by solar-powered boat," and it made stops on six continents to promote solar energy. Oh, and the team fended off Somalian pirates in the process, too. Now that it has a moment to catch its breath and soak up some rays at leisure, the MS Turanor could become any number of things -- from the world's largest solar battery to a "green luxury yacht." The latter option would certainly befit its chichi home port.
