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.

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.
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.

Increasing efficiency of solar panel
Generally when we orient a solar panel in a particular direction the Sun light will be. incident at various angles throughout the day instead of the perpendicular incidence it will be incident at various angles by which we will not be able to get maximum output the output will be maximum only at a particular time of the day but when we orient the solar panel perpendicularly to direction of the sunlight then we'll be able to achieve more output this can be done by attaching the stepper motor which is run by a.
Nanotechnology for More Efficient Solar Cells Interview with Prof. Jillian Buriak
What nanotechnology is, is a number of different concepts, ideas, and approaches for doing many things. So for instance, we work a lot in the area of renewable energies so we're using the concepts that we've learned from nanotechnology being able to control things at the atomic and molecular scale to be able to make more efficient solar cells, for instance to be able to take energy from the sun and transform that into electricity that you can then use for anything. So there are a few reasons why getting away from fossil fuels.
Is important. When you look at the amount of energy that humanity's going to require by say 2050, using the most conservative estimates that we've got, our energy needs are going to double and by 2100, they're going to probably triple. When you think about the security, the economic security, the social security of humanity, as this living species, as a civilization on this planet, we really need inexpensive sustainable sources of energy. I call this a quiet revolution because for the first time, I think in a history of science,.
Is that you've got the distinct silos you got the biologist talking to physicist, talking to the medical people, all using the tools and the enabling technologies of nanotechnology to solve these big problems. I think that we have a very important responsibility to share with the public our results, to be able to be accessible because I'm paying the bills, you're paying the bills, we're all paying the bills as taxpayers. And we should be available, and we should be able to speak freely about our research because that's what the public pays us to do.
Saving Energy with Solar Power Designing Windmill Blades for Energy Efficiency
The other thing is, when you want to build one, it's very difficult to get the right shape of the blades because these blades have to be very carefully designed that they get most out of it. You would not believe it, but when you see it here, these blades are spinning 3 times faster than the wind. Why Because of the design of the blades, they can spin faster than the wind is blowing. The windmill by itself will start producing electricity with about 6 to 7 miles per hour and then it goes up and gets its peak, its.
