We can print our own solar cells on an inkjet printer
2008-03-21 14:25:00 People have been looking for alternative energy solutions for a long time now. Solar cells are a pretty good way of using the sun's light to create energy instead of using fossil fuels and different types of machines. The main problem with these solar cells is that they are pricey and not everyone can afford installing a set.Here is where Konarka Technologies comes in with low cost sources of renewable power cells. These guys think that we can build our own solar cells by printing them with an inkjet printer. The company has patented a printable solar film from light-activated Power Plastic® that is flexible and using solar cells as ink we get our lightweight, cheap and thin photovoltaic solar cells. So far the technology is available to large corporations, but we hope we'll get to see it working in our own homes, soon. “This essential breakthrough in the field of printed solar cells positions Konarka as an emerging leader in printed photovoltaics.”
Mitsubishi boosts output of solar cells
2008-03-19 18:52:00 We've written before about Honda's production of solar cells, but did you know that Mitsubishi actually ranks as the world's sixth-largest manufacturer of PV cells? Currently, Mitsubishi Electric cranks out about 120 megawatts worth of solar cells a year, although they have the capacity for 150 megawatts. They plan to increase production to 230 annual megawatts by April of 2009. Solar cells are a hot commodity these days as the power industry, just like the automotive industry, is in the process of "greening" their image. In fact, Mitsubishi believes that the worldwide demand for solar cells could quadruple to 10,000 megawatts as early as 2010. If demand remains high, Mitsubishi Electric could increase its output to 500 megawatts by 2012.

TECHNOLOGY: Screen-Printed Solar Cells
2008-02-08 17:20:00 Members of the Fraunhofer Institute for Solar Energy Systems ISE are traveling to Tokyo with bulky luggage these days. Their destination is Nanotech 2008, the world's largest trade fair for nanotechnology. Their solar module, which they will be presenting in the BMBF marketing campaign 'Nanotech Germany', is the size and shape of a door: two meters high and sixty centimeters wide.The key component of the new modules is an organic dye which in combination with nanoparticles converts sunlight into electricity. Due to the small size of the nanoparticles, the modules are semi-transparent. This aspect makes them well suited for facade integration. The solar module prototype manufactured by the researchers at Fraunhofer ISE is amber in color. It is possible, however, to produce the modules in other colors, or even to print images or text on the module so that it serves as a decorative element.These design options open up an entirely new range of possible applications.

Nano Flakes Solar Cells
2008-01-24 15:11:00 Nano Flakes May Revolutionize Solar Cells ScienceDaily (Dec. 19, 2007) — A new material, nano flakes, may revolutionise the transformation of solar energy to electricity. If so, even ordinary households can benefit from solar electricity and save money in the future. If researcher Martin Aagesen’s future solar cells meet the expectations, both your economy and the environment will benefit from the research. Less than 1 per cent of the world’s electricity comes from the sun because it is difficult to transform solar energy to electricity. But Martin Aagesen’s discovery may be a huge step towards boosting the exploitation of solar energy. "We believe that the nano flakes have the potential to convert up to 30 per cent of the solar energy into electricity and that is twice the amount that we convert today," says Martin Aagesen who is a PhD from the Nano-Science Center and the Niels Bohr Institute at University of Copenhagen. During his work on...

Solar cells that work at night?
2008-01-10 21:00:00 The Idaho National Laboratory, Microcontinuum, Inc. and Patrick Pinhero from the University of Missouri are developing an exciting new technology which uses "nano-antennas" to capture solar energy. What is especially cool about this new solar technology is that it would operate both during the day and at night by using the leftover radiation after the sun goes down. Each nano-antenna is a spiral as wide as 1/25 the diameter of a human hair, meaning that many of them can be fit into a tiny space, and may be as much as 80 percent efficient. At this time, researchers have a ways to go before the technology is commercialized, but they are hoping that their finished product would be no more expensive as a coating than a cheap layer of carpeting.

Graphene the next big thing for Solar Cells and LCDs?
2007-12-30 16:21:00 We all know the fact that certain resources like Oil are very limited thats why theirs the mad dash at least in some fields to find an alternative to replace the non-renewable materials we use today for materials that are more than abundant (like water/hydrogen in the case of Oil). What you probably don't know is that one of the biggest most important materials for thing's like solar cell's and LCD's as well as other devices that have transparent electrodes to carry out functions, is also on the chopping block. The fact is a material known as Indium that is essential to thing's like Solar Cells and LCDs to being created is already running low. Estimates put the worlds supply of Indium at around 10 years from being completely gone. What would that mean? Well lets just say that the solar field would stop production of new panels, LCD's would stop production and we'd be thrown back quite a white to using RPTV's something very few people are anxious to do, the fact is the lac...

Graphene could be used in creating solar cells, LCDs
2007-12-30 11:09:00 Filed under: Displays, Misc. GadgetsNot to sound alarming or anything, but apparently, we've only got a decade or so before our planet runs clean out of indium. Thankfully for us, a team of researchers at the Max Planck Institute for Polymer Research in Germany are purportedly onto a replacement. For those in the dark, indium is a critical resource in "creating solar cells, LCD and other devices which must have transparent electrodes to carry out their function," but the aforementioned crew has seemingly been able to take graphene ("single layer 2D sheets extracted from the common material graphite") and build an acceptable alternative. The creation is 80-percent transparent to visible light and 100-percent transparent to infrared light, which could actually lead to solar cells capable of soaking up even more energy from more of the EM spectrum. 'Course, there's no telling how close this discovery is to being commercially viable, but we suppose we could always resurrect RPTVs and...

Printed solar cells. Solar energy at a tenth of the price.
2007-11-17 19:07:00 Ordinary solar cells are pretty complicated technology, even though the theories behind them are reasonably simple. They will also be expensive since the manufacture gets pretty much as complicated as the tech. Now, however, a couple of companies have presented ideas for the manufacture of solar cells that in principle means that they can be printed on a thin metal film. Since manufacture with the printing method would resemble an ordinary printing press, the cost could be a tenth of what is the case today, and they could make solar energy available to more, and cheaper than fossil fuels. One of the companies is American Nanosolar, who recently were awarded Innovation of the year by Popular Science magazine.
