Elon Musk: Tesla's Solar Roofs Will Be Cheaper Than Regular Roofs & Have "Infinity Warranty" In Brief Last night, Elon Musk announced that Tesla's solar roofs would be on sale starting today.
At the time, he also stated that more information on the panels was forthcoming. Hot Solar Cells: 10 Breakthrough Technologies 2017 - MIT Technology Review. Availability: 10 to 15 years by James Temple Solar panels cover a growing number of rooftops, but even decades after they were first developed, the slabs of silicon remain bulky, expensive, and inefficient.
Fundamental limitations prevent these conventional photovoltaics from absorbing more than a fraction of the energy in sunlight. Hot Solar Cells: 10 Breakthrough Technologies 2017 - MIT Technology Review. NowThis Future - New Solar Technology Turns Any Surface... 10 Breakthrough Technologies 2017: Hot Solar Cells. Non-toxic solvent removes barrier to commercialization of perovskite solar cells. Scientists at Oxford University have developed a solvent system with reduced toxicity that can be used in the manufacture of perovskite solar cells, clearing one of the barriers to the commercialisation of a technology that promises to revolutionise the solar industry.
Perovskites - a family of materials with the crystal structure of calcium titanate - have been described as a 'wonder material' and shown to be almost as efficient as silicon in harnessing solar energy, as well as being significantly cheaper to produce. By combining methylamine and acetonitrile, researchers have developed a clean solvent with a low boiling point and low viscosity that quickly crystallises perovskite films at room temperature and could be used to help coat large solar panels with the material. The results are published in the Royal Society of Chemistry journal Energy & Environmental Science. Virginia Tech flexible solar panel goes where silicon can't. In the very near future, recycling light energy may be easier than recycling any other item in your house.
Led by Shashank Priya, a team of mechanical and materials engineers and chemists at Virginia Tech, including post-doctoral researchers Xiaojia Zheng and Congcong Wu, as well as College of Science chemistry Professor Robert Moore and Assistant Professor Amanda Morris, is producing flexible solar panels that can become part of window shades or wallpaper that will capture light from the sun as well as light from sources inside buildings. Solar modules less than half-a-millimeter thick are being created through a screen-printing process using low-temperature titanium oxide paste as part of a five-layer structure that creates thin, flexible panels similar to tiles in one's bathroom.
Perovskite solar cells hit new world efficiency record. They're flexible, cheap to produce and simple to make - which is why perovskites are the hottest new material in solar cell design.
And now, engineers at Australia's University of New South Wales in Sydney have smashed the trendy new compound's world efficiency record. Speaking at the Asia-Pacific Solar Research Conference in Canberra on Friday 2 December, Anita Ho-Baillie, a Senior Research Fellow at the Australian Centre for Advanced Photovoltaics (ACAP), announced that her team at UNSW has achieved the highest efficiency rating with the largest perovskite solar cells to date. The 12.1% efficiency rating was for a 16 cm2 perovskite solar cell, the largest single perovskite photovoltaic cell certified with the highest energy conversion efficiency, and was independently confirmed by the international testing centre Newport Corp, in Bozeman, Montana. Combining conventional and concentrated solar technology results in efficiency gains. MIT's artificial leaf is ten times more efficient than the real thing. Speaking at the National Meeting of the American Chemical Society in California, MIT professor Daniel Nocera claims to have created an artificial leaf, made from stable and inexpensive materials, which mimics nature's photosynthesis process.
The device is an advanced solar cell, no bigger than a typical playing card, which is left floating in a pool of water. Then, much like a natural leaf, it uses sunlight to split the water into its two core components, oxygen and hydrogen, which are stored in a fuel cell to be used when producing electricity. Forget solar panels, optical ‘rectenna’ converts light directly to electricity.
From Georgia Tech, a news release that we missed when it first came out, but still well worth talking about.
First Optical Rectenna – Combined Rectifier and Antenna – Converts Light to DC Current Using nanometer-scale components, researchers have demonstrated the first optical rectenna, a device that combines the functions of an antenna and a rectifier diode to convert light directly into DC current. This schematic shows the components of the optical rectenna developed at the Georgia Institute of Technology. (Credit: Thomas Bougher, Georgia Tech) Based on multiwall carbon nanotubes and tiny rectifiers fabricated onto them, the optical rectennas could provide a new technology for photodetectors that would operate without the need for cooling, energy harvesters that would convert waste heat to electricity – and ultimately for a new way to efficiently capture solar energy. “The physics and the scientific concepts have been out there,” said Cola. Like this: Elon Musk Announces That SolarCity Will Create a Roof Made Entirely of Solar Panels. In Brief The next project for newly acquired company SolarCity?
Solar panels that aren't just added to existing roofs, it's actually THE roof. Solar Roof SolarCity, the company recently acquired by Elon Musk’s Tesla Motors, has just announced what’s next in the pipeline—a roof made entirely of solar panels. The announcement of their new “solar roof” was revealed by SolarCity chairman, Elon Musk, who says the they will not only look better but also last longer than current, traditional roofs. Tata Steel to Turn Steel Sheets into Solar Cells Using Spray-on PV Coating. A group of organisations including Tata Steel-led Corus and Swansea University (Wales, UK) are developing a new technology that would convert steel sheets into power generating solar cells.
The technology involves coating steel sheets with photo-sensitive dyes. The technology has significant applications since it is highly efficient even in diffused sunlight. Therefore, countries at higher latitudes or those with limited solar energy resource can generate significant amounts of solar-powered electricity with going for large-scale power plants. If extended, the technology can find its way to the automobile industry where photo-sensitive dyes can be applied to cars to generate electricity to split water into hydrogen and oxygen for fuel cells. Tata recently invested in an American company, Sun Catalytix, which integrates low-cost catalyst with solar-powered fuel cells to generate power. Cientistas australianos criam célula fotovoltaica 34,5% mais eficiente – CicloVivo.
Startup cria placas fotovoltaicas que se camuflam às superfícies – CicloVivo. This Hot Water System Can Save You Up to 80% on Energy Bills (Videos) New Printable Solar Panels Are Ready To Hit The Market! IBM Solar Collector Magnifies Sun By 2000X – These Could Provide Power To The Entire Planet. A team at IBM recently developed what they call a High Concentration Photo Voltaic Thermal (HCPVT) system that is capable of concentrating the power of 2,000 suns, they are even claiming to be able to concentrate energy safely up to 5,000X, that’s huge.
The process of trapping the sunlight produces water that can be used to produce filtered drinkable water, or used for other things like air conditioning etc. Scientists envision that the HCPVT system could provide sustainable energy and fresh water to communities all around the world. “Each 1cmX1cm chip can convert 200-250 watts, on average, over a typical eight-hour day in a sunny region. In the HCPVT system, instead of heating a building, the 90 degree Celsius water will pass through a porous membrane distillation system where it is then vaporized and desalinated. The heat is absorbed into hundreds of tiny solar cells called photovoltaic chips. This project is being funded by the Swiss Commission for Technology and Innovation. The Solar Sunflower: Harnessing the power of 5,000 suns.
Sebastian Anthony Behold, the Solar Sunflower! Here they are trying a bunch of different reflector materials, which is why the segments all look slightly different. Some of the reflectors are covered up to protect them from the elements, or to stop them from frying a nearby engineer. Sebastian Anthony Behold, the Solar Sunflower! EWAO Nigerian Man Turns A VW Beetle Into A Solar And Wind Powered Car. This is one of the coolest ideas and to top it off it’s completely reasonable too! Segun Oyeyiola was a student at Obagemi Awolowo University and while he was in attendance there, he converted his gas thirsty Volkswagen into a completely green energy machine by installing a large solar panel on the top of the car, with an additional wind turbine underneath the hood. His idea is to have his concept of his new invention to become “Nigeria’s future car.”
At birth, the battery took 4-5 hours to charge, that was definitely not ideal. Yet the largest challenge, according to Mr. Oyeyiola, was obtaining the best materials to use, and it didn’t help at all being surrounded by people telling him that he was wasting his time. Check out this animation of a solar/wind-powered vehicle, illustrating how the batteries are charged via the multiple turbines. Under the hood of this bad boy boasts three wind turbines that transfer air into energy and is then stored in the main battery. Vascular Channels Based On Plant Leaves Allow For Self-Healing In New Solar Cells.
Clean Power Published on August 15th, 2013 | by James Ayre Self-healing solar cells — possessing “vascular” networks similar to those in plant leaves — have now been created by researchers from North Carolina State University. The new solar cells are able to effectively and inexpensively restore themselves to optimal functioning thanks to their possession of a “network of channels” which mimics the organic vascular systems found in most plants. North Carolina State University explains: In their new paper, the researchers show that creating solar cell devices with channels that mimic organic vascular systems can effectively reinvigorate solar cells whose performance deteriorates due to degradation by the sun’s ultraviolet rays.
A Seriously Bright Idea That's Giving An Amazing New Purpose To Something We Usually Throw Away. Solar-Powered LED Clothespins Light Up Urban Nights - WebEcoist. While we can’t exactly call this a ‘sustainable’ version of a clothespin, since it’s made of plastic and far more complicated than the simple ones made of renewable wood, it does have an interesting spin. Designers Idan Noyberg and Gal Bulka have created the ‘Lightly,’ a clothespin with built-in solar panels and LED lights that emit decorative ambient illumination once the sun goes down. The panels collect sunlight by day while a sensor automatically cues the lights to turn on at dusk. Of course, the design is waterproof, so leaving them out in the weather is no problem. Sure, clothespins don’t need to have lights built in, but imagine how much cooler lines of laundry would look hanging in backyards or billowing in the wind on city streets if they were covered in tiny multicolored lights. This glass sphere might revolutionize solar power on Earth.
German architect André Broessel, of Rawlemon, has looked into his crystal ball and seen the future of renewable energy. This solar panel printer can make 33 feet of solar cells per minute. Whatever oil and gas true believers want to think, the world is doing this solar power thing. It’s getting cheaper and cheaper to make solar panels, and the panels are getting more and more effective. New Material Converts Sunlight to Steam. Spray-On Solar Power Will Likely Soon Change The World. The Power Cube: It generates, it Internets, and it's back. Seven years ago we first covered the Magic Box That Does Everything, the Ecos LifeLink. Design Concepts. Hybrid Material May Help Crush Solar Cell Efficiency Record. During photosynthesis, plants only convert about 10% of the light they receive from the sun into usable hydrogen to fuel the reaction.
Last summer, a group of researchers were able to break the world record for laboratory efficiency by reaching 44.7% with a new cell, with 50% as the ultimate goal. German Engineer 3D Prints World’s First Solar Powered Stirling Engine. Each and every day, I am blown away in yet another way by all of the new innovations that have quickly been coming into existence within the 3D printing space. It seems as though just a couple years ago no one even knew what 3D printing was, and today we have everything from 3D printed houses to 3D printed cars, prosthetic hands, electronics, and more.
