Solar Panel Manufacturing Processes
Cheap solar panels as thin as paper!
In the wake of news that now leads the production of renewable energy from fossil fuels in terms of investment, companies like Xunlight are demonstrating the ability to manufacture thin film silicon solar in the hope of conquering a market share of market makers strained silicon solar panels. Xunlight for the manufacturing process is to print amorphous silicon solar cells in the leaves of stainless steel so thin you can roll like a model. And in a sense, they are - a project for strengthening health systems integrated photovoltaic (BIPV), which promises more solar energy surfaces faster and cheaper.
manufacturing process Xunlight creates solar "leaves" of 36 inches wide and a mile long, with a nine-layer chemical vapor deposition of semiconductor materials, and a reflective layer on the bottom and the surface of an electrode through the layer sputtering process. The resulting sheet, a hundred times thinner than a typical piece of paper, used only a limited quantity of silicon to create the triple-junction solar cells.
These amorphous (not crystalline configuration) of solar cells are much less expensive to manufacture, providing affordable solar energy really in a lightweight format that can be used on many surfaces, backpacks buildings to produce electricity.
The drawback is a rate of return of 8 percent, which is significantly lower than that of traditional crystalline silicon panels by 20 percent. Reports Xunlight efficiency achieved through the incorporation three different materials (amorphous silicon, germanium, amorphous silicon and nanocrystalline silicon) that capture light at different wavelengths, to remedy deficiencies in the band gap of film and other thin crystalline solar cells with a single subject premium.
In fact, the efficiency scores are the only disadvantage of thin film solar - a problem which tends to overshadow its usefulness in many applications because of its flexibility. This is due to the inherent nature of amorphous silicon, whose structure is less reliable, resulting in degradation in the presence of sunlight sunlight or high temperatures. Some solar concentrator technologies that promise to remedy this inefficiency are still on the drawing board.
Xunlight now binds to the thin film career with other companies (HelioVolt, Nanosolar, and United Solar Ovonic) to obtain a thin film crystalline solar efficiency coincide. Xunlight has the advantage of a large volume, the technical roll-roll, but the two former companies use copper indium gallium selenide (CIGS) that is competitive with crystalline solar in terms of efficiency. Unfortunately, nobody has been able to make a cheap product in volume, for CIGS is so difficult to work with them.
thin film in its current version also has the inherent risk of easy permeability and flammability, but imagine that solar installers day can thin rolls up to the ceiling, install and have a watertight roof that is also a pleasure for homeowners. And thanks to the Recovery and Reinvestment Act of 2009, millions in financing business leaders who think they can achieve this goal.

Why are quality solar cells space much more than shopping?
I understand they have a much more efficient, but I 'm looking for more details. I attended an engineering program at the University of Michigan during the summer and took a tour of naval architecture, and my group showed a small plane with rechargeable batteries and solar energy. Panels who had, perhaps numbering 30 in ^ 2, were within quality and cost more than $ 30,000. That seems very excessive. Is there something about the manufacturing process of these cells that determines the price so high? Or is the problem most associated with the process of being patented? How extensive is the research that will also take to reduce the cost of such cells, or the effectiveness of education commercial cells these standards?
What we really need to do is look at the price per unit of energy plate ... U.S. dollars per watt. Just look at the cost of the system that makes you forget the size of the plate system. PV on a spacecraft are the only energy source to do so. better than the production of energy as needed. Photovoltaics in a residential or commercial property is more than one device Energy Booster. If power is a little more would be needed, not other sources such as utility to interact with the power buying and. As to why the price per watt would be higher for the use of spacecraft for use at ground level ... you must consider the environment are exposed to the spacecraft. The space ship is exposed to radiation by 30% farther from the Sun than the surface Earth because the Earth's surface has an attenuation of the atmosphere in Raleigh filter and reduce it. panels spacecraft must be capable of withstanding all that UV and X-rays of all that we are never subjected to the Earth. In addition, panels of the spacecraft are subjected to a lot of solar wind and meteorites, which are more damaging hail and wind air. Best built to withstand extreme environments.
