Melbourne researchers have successfully created Australia's largest and most flexible solar cells, with the aid of a new printer located at CSIRO. The scientists are part of a collaboration between research and industry partners called the Victorian Organic Solar Cell Consortium VICOSC. This was achieved through the collaboration between The University of Melbourne and the Bio21 Institute, CSIRO, Monash University and industry partners including Bluescope Steel and security printing firm Innovia Security. In just three years the consortium has gone from making cells the size of a fingernail, to cells 10 centimetres square.
They are now able to print organic photovoltaic cells the size of an A3 sheet of paper. The consortium is now leading the world in the ability to print solar cells and using different printing technologies, but this is the beginning of the story. We're still developing the technologies, still developing the materials to enable us to print in a number of different ways for different applications. The new printer can roll out 10 metres of solar cells per minute, which is equivalent to producing one cell every two seconds. Using semiconducting inks, the researchers print the cells.
Straight onto paperthin flexible plastic or steel. So what we're looking at is, how can we use this technology in the short term, how can we print solar cells to enable advertising, can we put solar cells on to advertising material in shopping centres to drive an active display. So if somebody wants to advertise something with nice flashing lights then at the moment they drive that with batteries. In the longer term we see these materials being able to be coated on to buildings, into windows and on roofs to provide.
Power in a wide variety of locations and circumstances. As part of the consortium, graduate students working alongside scientists are involved in training and development programs to improve the technology in the long term. We're now right up there with the rest of the people in the world but we've also got a facility which is different. We now have a process through our collaboration where we take things from the very very beginning, from designing materials, from making devices in the lab scale right through the large scale printing, which is very very unusual in the world context.
SolarCity Unveils Worlds Most Efficient Rooftop Solar Panel with more than 22 Module Efficiency.
The Sun provides endless energy, but the average solar cell panel can convert only 14 to 20 of the energy it collects into usable electricity. Now, American energy company SolarCity has built the world's most efficient rooftop solar panel, with a module efficiency exceeding 22 percent. The new SolarCity panel generates more power per square foot and harvests more energy over a year than any other rooftop panel in production, and will be the highest volume solar panel manufactured in the Western Hemisphere. SolarCity will begin producing the first modules in small quantities this month at its 100.
MW pilot facility, but the majority of the new solar panels will ultimately be produced at SolarCity's 1 GW facility in Buffalo, New York. SolarCity expects to be producing between 9,000 10,000 solar panels each day with similar efficiency when the Buffalo facility reaches full capacity. SolarCity's panel was measured with 22.04 percent modulelevel efficiency by Renewable Energy Test Center, a thirdparty certification testing provider for photovoltaic and renewable energy products. SolarCity's new panel is created via a proprietary process that significantly reduces the manufacturing cost relative to other highefficiency technologies, and it.
Why Should We Launch Solar Panels Into Space
This episode of DNews is brought to you by Full Sail University. This week the Japanese Aerospace Exploration Agency announced it wants to get solar power from space. I'm having flashbacks to disasters from SimCity2000. Hello! I'm Trace. Thank you for watching DNews. Back in the 1960s, American aerospace engineer Peter Glaser proposed launching solar panels into space, and beaming the power they collect back to the surface for our use. Since the late 60s the idea has been in a holding pattern mainly because of the expense and worries about maintenance and equipment, but thanks.
To recent developments in solar panel tech the Japanese space firm JAXA says they can finally try it. The plan is ambitious at minimum and cost hasn't yet been calculated, BUT JAXA is determined, and they're not the only ones. The U.S. Naval Research Laboratory is also interested in spacebased solar. The reason everyone's looking up, is because that's where the sun sits! If we can put a satellite in orbit to collect the sun's rays BEFORE the atmosphere filters them out, and without the worry of a cloudy day, that would be rad. The JAXA Space Based Power System.
Or SBPS will orbit 22,400 miles up, and if done to their specs, would completely replace a nuclear power plant by producing 1 gigawatt of electricity enough to power halfamillion homes. Their plan uses a 10,000 metric ton system, which is. well pretty ridiculous. The largest rocket ever launched was the Saturn V it took our boys to the moon and could only lift about 130 metric tons. Once the power is gathered, a converter in space will convert the electricity into a microwave beam not like in your house, literally waves of energy that are.
On the micro scale. Microwaves can be converted from energy at 80 percent efficiency, which means there would be some loss, but it would be pretty damn efficient about 48 of the power collected would reach consumers. Which doesn't sound great, but it really is. To make sure the array is getting sunlight 24hours a day, JAXA plans to put mirrors on either side of the planet to reflect sunlight at the collector all the time. The Japanese are announcing their plan so far in advance in the hope other countries.
Will gather and help realize the dream of solar from space. Once created, it could provide clean, unlimited energy anywhere on the planet, regardless of remote location. Here's the kicker. It would cost about a trillion dollars. Which sounds like a lot, but it's like 125 bucks per person on the planet in 2030. And that's WAY more than you're paying doe your power bill. Not to mention oil wars and all the pollution, ecological damage, mining and drilling that goes with fossil fuels. We've got commenting areaaassss, check them out and type your feelings on spacebased.
Solar so we can all talk about it! None of this would be possible without computers to run the system, and we need people to write the computer programs. Full Sail University in Florida offers courses to help train tech professionals by blending code and realworld experience. Students of Full Sail have handson access to technology on their first day, get a discounted laptop and all the software they'll need to earn degrees in software, mobile and web development.

The Future of Solar Energy is TINY Technology!
The future is huge for tiny technology. Miniaturization is, perhaps ironically, a huge deal. I mean, without it we wouldn't have had the personal computer revolution and we wouldn't have this world we live in now, where we have smartphones and tablets and other devices just as powerful as a computer, that can fit in the palm of your hand. But even these gadgets are gargantuan compared to nanotechnology! See, a nanometer is just one billionth of a meter. And that's kind of hard to imagine, so let me put it to you this way.
Your typical sheet of paper is about one hundred thousand nanometers thick. And at this scale, individual elements are so small you can't even see them with a light microscope. Now as we learn more about how materials behave on the nanoscale, we have more potential applications to use that knowledge practically. I'm talking about how nanotech could help solar panel technology. And fortunately, at a recent meeting of the American Association for the Advancement of Science, or AAAS, they had a panel on just this very subject. Now if you know anything about solar panels you know they have some drawbacks. For example,.
Efficiency they max out at around twenty percent in the field under ideal conditions. They're also rigid, so you can't just put them anywhere you like. And they tend to be expensive because manufacturing them is complicated. But scientists hope that nanotechnology can help address all three of these challenges. Now with efficiency they're looking to nature specifically, moth eyes. You see, moths have these little tiny structures in their eyes that help reflect light back into the eye and it does two things it lets them see better in the dark, and it cuts down.
On reflection so predators can't spot them as easily. With solar panels it could actually make them more efficient by reflecting more of the sun's light into the panel so you lose less in reflection. And when we're talking about flexibility, well nanomaterials are really, really small, and there is the potential to create solar panels that are just a few sheets of molecules thick. They could be as flexible as a sheet of paper, and with that kind of flexibility you could put those pretty much anywhere you wanted to.
And as for price, well, that's the big one. And in the short term I don't think it's going to turn around. But scientists are cautiously optimistic that nanotechnology will let us use new processes, like printing solar panels directly onto a substrate using just a specialized printer. That would actually be less complicated and expensive than traditional manufacturing methods. Now at that meeting of the AAAS, a Dr. Wolfgang Porod gave a talk about Nanoantenna Thermocouples for Energy Harvesting. Which I admit sounds like technobabble straight out of a Star Trek episode.
But it's actually fairly simple once you break it down. A nanoantenna is just an antenna on the nanoscale. These resonate with longwave infrared radiation. And a thermocouple Well that's a component of circuitry that generates a voltage when one part of the thermocouple is a different temperature than other part. So you pair these two together and the antenna generates heat and the thermocouple generates voltage. It could actually help increase the efficiency of solar panels. Now like I said, nanotechnology is a young science and it has lots of different applications.
Across many disciplines. And I'm really excited how such a small technology could have such a huge impact. That leads me to this week's question. When I say the word nanotechnology what do you imagine What does that word mean to you Let us know in the comments below. Then, do me a nanosized favor and share this tutorial with your friends.

DIY Solar Panel System Cost
The total of the system and materials was $22K. I ended up spending about another $1,800 in permit fees and a structural engineer and $400 for an electrician, several hundred dollars for a guy to come help me out for the two afternoons he spent with me. Xcel Energy gave me $16,538 rebate. Fix cost based on the number of kilowatts you are installing and has nothing to do with how much you pay the permit office or the electrician. My final cost after rebate was $7,237. I started my research in solar probably about a year before I actually installed it went.
And got a couple of bids from some of the local solar people both from contractors that my friends have used as well as just searching the internet and while talking to one of the guys I find of developed a good feeling from him, and I asked the question Would it be possible to do some of the work myself and kind of learn along the way he said Sure I absolutely support the doityourselfer DIY so I said why don't you throw me bids, what it would cost just come home and have solar one day and what it would cost to have.
It done where I do some or all the work myself. And throw them both to me and I said let's try the second one. The guys name is Steve Cross from Sun Spot Solar. I gave him my electric bills and said this is how much I think I need to generate and he said I agree and lets do these types of panels 180 watts each, you will need some where around 19 to 22 we figured out 21 fit pretty well. So I went and got all the permit information from Golden, filled it out. He came by 12.
Hour one day he type all the Xcel application on the internet and I kind of ran the process and when I had a question I would just send him an email and he helped me out. I think in parallel we order the equipment he dropped off in my driveway. Then one of his installers came out and helped me for two afternoons and I pretty much myself put in the whole rack system on the roof and the installer came out and helped me kind of a two man job carrying the panels up, putting the panels down and bracketing them down.
How to Install Solar Panels Wiring Fuses to Solar Panel DC Side
Alright, now we're ready to wire up our fuses and charge controller on the solar panel DC side. We've got our charge controller ready to go, we're just going to slip our BX wire, which I've actually insulated one of the tips, here, so we don't spark our machine. We'll feed that wire through a strainer leaf and put another little strainer leafer, here, on our BX. Tighten that up a bit. So you can see with that little spark there, that we do have power and we should use some.
Kind of fusing in here just so, if something goes wrong and the fuse blows out instead of the electronics. So, we've got a standard car fuse, this one's rated 40 amps at 32 volts. Really, all we need is about a 15 amp fuse, here, but this should give us some measure of protection. We're going to wire this through on the positive side. We've got a fuse holder that matches our fuse, and we'll just strip off a little bit of this insulation here. We'll form a little edge, a crimp, on this so it will loop under our device nicely. Got.
Screw terminals, here, and we're just going to slip that positive wire right under one of our terminals. In a larger installation this will be done in a separate box, but for a small one, this should be fine. Now, we need to run the other side of the positive wire to our charge controller and we need a little piece of wire for that. So now we've got our little jumper wire ready to go, we're going to strip that off and connect it to the other side of our fuse. Demo So.
Los Alamos Discovers Super Efficient Solar Using Perovskite Crystals
Aditya Mohite Our group focuses on converting solar energy into electricity. And we're working on a class of solar cells which are referred to as third generation solar cells. The goal of our project was, how do we take these materials and control their crystalline properties, crystalline size, and get them to a point which are comparable to what is used in daytoday semiconductor industry like gallium arsenide or silicon. We're not there yet, silicon is the holy grail, but one of the biggest advantages of this material, at least from what we've begun to discover, is that you can make very high.
Quality crystals off this material which are large area, they are single crystalline, and they have properties which are at par with silicon or gallium arsenide. There's a lot of work that needs to be done in the engineering aspect of things, in terms of the stability you're trying to get, the right electrical contacts for them to perform at par with silicon, but I would say that this is something which will be achieved in the coming years. Wanyi Nie So, we developed a new technique, it's called the hot casting process, where we keep.
Our substrate hot and solution hot and do the spincoating at elevated temperature and at the same time the film color will be converted from light yellow to dark brown which means we're forming a highquality crystalline grain, and if we look at it under the microscope we are able to achieve up to millimeter scale large crystal grains. Normally for the crystals to grow usually require high temperature or sophisticated processing, but this method is kind of low temperature and easy solution processing. Mohite There has always beena lot of defects and disorder and multiple interfaces.
That has plagued efficiencies, and so by growing these crystals of highquality you have sort of circumvented that problem and solved an important bottleneck which has existed in this field of nanomaterial, solutionbased solar cells, third generation solar cells. Solar energy is trying to tap into the unlimited amount of solar energy that falls on Earth and that's basically free, and if you can harvest that at a very, very low cost, much cheaper that what is used, by burning coal for example, and fossil fuels, then that gives us a route to really be completely energy.
Printing Australias largest solar cells
Dr Scott Watkins We're really pleased to commission what is now Australia's largest facility for printing thin film solar cells. This equipment that has been purchased over the last few months and commissioned in our labs here in Melbourne will enable us to print A3 size solar cells. We've rapidly scaled up making our devices from fingernail size in the lab to A3 size devices that are fully printed now. And at this size we're definitely up there with the best in the world. In the short term we're looking for applications in consumer devices.
