If the future is not surprising with disruptive technologies, those that change everything in the production of green energy, solar has a great future. Especially if we continue reaping inventions like these, that they improve their efficiency in a way unthinkable to do anything.
The first one points to the stars. Not only because it is located on the heights beyond the clouds, but also because it is an invention of high-minded, with incredible potential that could revolutionize the landscape of green energy.
The second does not imply major changes. Apparently not, at least.
The difference is barely noticeable, but the small addition makes a difference which is expected Al kankariya efficiency almost twice the current.
Electricity and hydrogen with floating panels
The first project aims mentioned that greater use of solar energy with a dual approach: the production of hydrogen and electricity at the same time.
Increased efficiency pursued this project goes beyond the traditional concept of solar panels by placing them in a high altitude balloons. The aim is to overcome the clouds, so the amount of sunlight it receives is higher, multiplying its Performance.
Found in the highest, in a hydrogen-filled balloons about 20 kilometers altitude, it means that weather conditions do not interfere with what we remove a factor often pose a serious problem.
So ingenious them, since photovoltaic cells can only seize a portion of the solar spectrum, let it be greater in order to increase efficiency. Of course, once you get increased efficiency thereof, the invention could multiply your results.
In turn, researchers NexPV, a laboratory in which the French National Center for Scientific Research and the University of Tokyo are working, have devised a proposal that involves connecting balloons through cables for electricity production continuously.
Although it is still just a project, the responsible French Japanese laboratory are confident they can make it happen. The prototype will be launched in 2016 and since its results will improve.
Your advantage? Up there, the source of solar energy reaching the plates five times more abundant than on the ground, while that convert solar energy into hydrogen, which does not need to store it in batteries. Your main drawback?
Perhaps if possible accidents balloons break down or other risks associated with the proximity of the airspace and its actual feasibility.
To its credit, the existence of projects in balloons to altitudes even higher than the 20 km that have proved viable. And why not, perhaps this is only a first impression from the work to go to find the right formula.
The viability of the project also depends on its cost, an aspect on which its inventors also have spoken. A price must take into account spending on infrastructure, maintenance and durability.
Key issues on which nothing is known, probably because even they know by now the project.
Almost double coating efficiency
The second of the inventions is not so spectacular, but not make it any less interesting. His proposal is to coat the glass of solar panels with a special coating that increases their efficiency from almost any angle.
The material from which the plates are coated is a glass coating is only possible to manufacture using nanotechnology. Specifically, it is a ultra fine rods and honeycomb structure.
The result is increased efficiency of the cell still varies depending on the angle, but with a higher productivity which varies from 5 to 28 percent. In the long term, researchers hope that improved efficiency could reach that 46 percent.
Thereby it is increasing productivity. That is, the amount of solar energy that can make every solar cell. In fact, until now one of the major drawbacks of the solar panels is the inability to attract the maximum solar energy by the same movement of the sun and the position thereof.
While only then take advantage of it, it is key to reach as many as possible, although he does irregularly over time. Consider that, in addition, we have the added difficulty of storage, the Achilles heel of both solar energy and wind power.
Thanks to the invention of the King Abdullah University of Science and Technology (KAUST, for its acronym in English) of Saudi Arabia, the innovative coating could increase efficiency by up to 46 percent.
In turn, the coating helps self-cleaning, also largely responsible for the productivity figure almost be doubled. This is gained in efficiency and equipment life.
As is known, the dust also reduces the amount of sunlight that reaches and, therefore, decrease productivity. An invention that is presented as an alternative to locating devices which change the position of the panels following the movement of the sun.
Its comparative advantage is not only avoid additional devices with footprint that entails at the time of manufacture and transfer or added expense in infrastructure, maintenance and energy supply. The eternal debate of where to direct also ignores.
