This solar panel printer can make 33 feet of solar cells per minute

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. For example: A team in Australia just built a gigantic printer that spits out solar cells at a rate, Gizmodo reports, of about 33 feet every minute. It’s not even particularly complicated technology, according to the researchers. [The printer system] utilizes only existing printer technology to embed polymer solar cells (also known as organic or plastic solar cells) in thin sheets of plastic or steel at a rate of ten meters per minute. This particular type of cell isn’t the most efficient, but it’s the type that lends itself to uses where you need a little flexibility — solar windows, bags, or tents, for instances.

Zoom sur des films solaires autocollants | Chauffage Electrique Aterno Il sera peut-être bientôt possible de coller des cellules solaires adhésives sur nos fenêtres, téléphones portables, et sur tous les appareils susceptibles d’être alimentés par l’énergie solaire. En effet, une équipe de chercheurs au Laboratoire national des énergies renouvelables ( NRE ) a mis au point un dispositif utilisant des films solaires « détachables et applicables » sur de nombreux supports. Les scientifiques sont parvenus à mettre au point ces films autocollants en constatant que des couches de moins d’un micron d’épaisseur pouvaient être retirées du substrat d’une cellule en silicium en trempant ces dernières dans de l’eau à température ambiante. Ils ont ensuite exposés ces films à une température de 90°C pendant quelques secondes et ont observé qu’ils pouvaient être fixés sur n’importe quelle surface, puis retirés, comme des autocollants. Les chercheurs essaient désormais d’améliorer les performances de ces nouveaux films solaires autocollants.

MIT creates solar cell from grass clippings A researcher at MIT, Andreas Mershin, has created solar panels from agricultural waste such as cut grass and dead leaves. In a few years, Mershin says it’ll be possible to stir some grass clippings into a bag of cheap chemicals, paint the mixture on your roof, and immediately start producing electricity. If you remember high school biology classes, you will hopefully remember a process called photosynthesis, whereby plants turn sunlight into energy. Mershin has found a process which extracts the photosynthesizing molecules, called photosystem I, from plant matter. Photosystem I contains chlorophyll, the protein that actually converts photons into a flow of electrons. These molecules are then stabilized and spread on a glass substrate that’s covered in a forest of zinc oxide nanowires and titanium dioxide “sponges.” So far so good — now time for the reality check.

This solar power system makes electricity and clean water at the same time Most solar power systems are either photovoltaic or thermal — they work by collecting either electrical energy or heat energy. And they often use up tons of water. This system, designed by engineers in Switzerland, collects both electrical and thermal energy. And it desalinates water at the same time. The High Concentration PhotoVoltaic Thermal system — or HCPVT , which is pronounced by hiccuping and then blowing a raspberry — works on a basically the same principle as those giant fields of mirrors that concentrate sunlight at the tops of really, really tall towers. Only the HCPVT uses really small mirror facets and concentrates the energy in teeny tiny photovoltaic chips. That’s the electrical energy part. This is all about equivalent to patting your head and rubbing your belly at the same time.

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. In this case it’s a spherical sun-tracking solar energy-generating globe — essentially a giant glass marble on a robotic steel frame. But this marble is no toy. It concentrates both sunlight and moonlight up to 10,000 times — making its solar harvesting capabilities 35 percent more efficient than conventional dual-axis photovoltaic designs. André Broessel was a finalist in the World Technology Network Award 2013 with the globe’s design and afterward produced this latest version, called Betaray, which can concentrate diffuse light such as that from a cloudy day. André Broessel’s latest invention looks like something out of a superhero movie. In reality, though, it’s a stand-alone solar energy generator. But Broessel’s invention may be more than just aesthetically pleasing. “We can squeeze more juice out of the sun,” Broessel says. Source: NewsDiscovery

Les panneaux solaires chinois taxés à 47% Mise à jour du 12/06/2013 : La Commission européenne a finalement décidé de mettre en oeuvre des droits anti-dumping provisoires de 11% pendant 2 mois sur les panneaux solaires photovoltaïques chinois. Cette mesure « transitoire » servira à éviter une éventuelle rupture d’approvisionnement. Par contre, la taxe sera bien portée à 47% dès le 6 août 2013. Bruxelles a déclaré une guerre commerciale à la Chine : après une vaste enquête sur les pratiques de la Chine jugées anticoncurrentielles, la Commission a en effet proposé aux 27 pays membres de l’Union de taxer de manière temporaire les importations de panneaux solaires chinois à hauteur de 47% en moyenne ! Cette mesure sera soumise aux députés européens qui devraient la voter d’ici la fin du mois. Cette proposition est née pour faire face à l’importance de la Chine sur le secteur solaire en Europe. Une bataille difficile C’est une bataille difficile que s’apprête à mener Bruxelles puisque la Chine est son deuxième partenaire commercial.

New Material Converts Sunlight to Steam Researchers from MIT have developed a new material that converts sunlight into steam much more efficiently than currently available alternatives. This material acts sort of like a two-way sponge: it can attract and hold sunlight for heat and can also continually draw up water in order to create a constant supply of steam. The research was led by Hadi Ghasemi and the results were published in Nature Communications. “Steam is important for desalination, hygiene systems, and sterilization,” Ghasemi said in a press release. “Especially in remote areas where the sun is the only source of energy, if you can generate steam with solar energy, it would be very useful.” The system works in layers. “On the left, a representative structure for localization of heat; the cross section of structure and temperature distribution. When it is exposed to sunlight, the graphite flakes heat up. Solar-powered steam generation isn’t anything new, but this material is markedly more efficient.

[L’expert répond à vos questions] Comment recycler les panneaux solaires « Les panneaux photovoltaïques « usés » : que peut-on en faire ? Sont-ils recyclables ? » Cette semaine, c’est Véronique L. qui nous pose une question sur le recyclage des panneaux solaires. Les panneaux solaires photovoltaïques permettent de faire d’importantes économies sur la facture d’électricité grâce aux revenus qu’il est possible de tirer de la production d’électricité. Le recyclage des modules Un panneau photovoltaïque est composé essentiellement de verre, d’aluminium et de semi-conducteurs. Pour ce qui est des modules photovoltaïques à base de silicium cristallin, après séparation mécanique des câbles, boîtes de jonction et cadres métalliques, le recyclage de ces modules peut suivre deux voies : Une fois séparées des modules, les cellules subissent un traitement chimique qui permet d’extirper les contacts métalliques et la couche anti-reflet. Et la loi ? La législation européenne qui s’applique en termes de gestion des déchets s’appuie essentiellement sur 4 directives :

Spray-On Solar Power Will Likely Soon Change The World New Energy Technologies is developing the first-of-its kind SolarWindow™ technology, which enables see-through windows to generate electricity by ‘spraying’ their glass surfaces with New Energy’s electricity-generating coatings – the subject of forty two (42) patent filings. SolarWindow™ generates clean electricity on see-through glass windows, by making use of the energy of natural sunlight and artificial sources such as fluorescent and LED lighting typically installed in offices, schools, and commercial buildings. How do we generate electricity on see-through glass for commercial application in homes, offices, and commercial buildings?

L’hybride sur le toit Produire de l’électricité verte ou avoir de l’eau chaude, pourquoi choisir ? La start-up marseillaise Solaire 2G fondée en 2010 développe le premier panneau solaire hybride. Nommé DualSun, il produit d’un coté de l’électricité photovoltaïque et de l’autre, de l’eau chaude solaire. Cette idée novatrice a germé dans l’esprit de Jérome Mouterde, co-fondateur de la société. « Les panneaux solaires classiques ne convertissent en électricité que 15 % de l’énergie qu’ils reçoivent. Nous avons voulu valoriser les 85% restant. », explique cet ingénieur sorti de l’Ecole Centrale Paris. Actuellement en phase de développement, les panneaux 2 en 1 DualSun devrait être commercialisés en fin d’année. A titre d’exemple, pour une maison de quatre personnes à Lyon possédant une toiture orientée sud, 6 panneaux DualSun pourrait couvrir 44% des besoins annuel en eau chaude et produire 3 391 kwh/an soit une économie de 1 221€.

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.

Nouveau record d'efficacité pour une cellule solaire en CdTe > Solaire La société américaine First Solar a annoncé fin février avoir établi un nouveau record du monde de conversion pour des cellules solaires photovoltaïques en tellurure de cadmium (CdTe), avec un taux de 18,7 % confirmé par le Laboratoire américain sur les énergies renouvelables (NREL / USA). La cellule en question a été développée au centre R & D de l'usine de Perrysburg (Ohiao) en utilisant des procédés et des matériaux - y compris du substrat de verre - conçus à des fins de fabrication à grande échelle. "Cette réalisation met en valeur l'énorme potentiel du CdTe par rapport aux autres technologies photovoltaïques et met en évidence les gains de performance que nous continuons à réaliser grâce à notre investissement en R & D, cohérent et important", a déclaré Raffi Garabedian, directeur technique chez First Solar. ** First Solar utilise un processus de fabrication en continu qui transforme une feuille de verre en module solaire complet en moins de 2,5 heures.

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. I titled the post It Generates. It Internets. It Cools and Refreshes. And now, apparently, It Exists. It doesn't appear to cool and refresh with the water purification anymore, but it does still generate and internet, with up to 15 Kilowatts of power. This innovative patented solar technology has the potential to be one of the most important solar patented innovations of our generation. Patent Drawing/Public Domain Did I mention it is patented? None of the aforementioned prior art disclose the space saving arrangement of solar panels in the stowed position on top of the container of the inventive station. OK, so it's all about the drawer system and I guess that's patentable because they got it. Ecos Powercube/Screen capture But hey, I spent five years and a lot of money trying to patent something that nobody wanted or needed either, it becomes an obsession. More at Ecosphere techologies

Forget solar panels, here come building-integrated photovoltaics Solar panels are becoming passé. Why put solar panels on top of building construction materials when you could just tap the power of the sun directly through the construction materials themselves? Bloomberg reports on the rapid growth in building-integrated photovoltaics, or BIPV. These are solar power–harvesting cells that are incorporated into the walls, roofs, and windows of buildings — integrated seamlessly instead of being bolted onto a finished building as an apparent afterthought: From stadiums in Brazil to a bank headquarters in Britain, architects led by Norman Foster are integrating solar cells into the skin of buildings, helping the market for the technology triple within two years. … The market for solar laid onto buildings and into building materials is expected to grow to $7.5 billion by 2015 from about $2.1 billion, according to Accenture Plc, citing research from NanoMarkets. Expect green buildings of the future to look a lot more blue.
