Stepped down from the roof solar

In people’s eyes, the roof of IBM Laptop Battery photovoltaic cells has long been commonplace. But one day in the future, more compact than the current micro-photovoltaic cells will be applied in more areas, windows, roof sunshades and even their shadow will appear.
University of Illinois at Urbana - Champaign (University of Illinois, Urbana-Champaign) Professor of Materials Science and Engineering John Rogers (John A. Rogers) and his research team invented a new technology, makes the plastic, cloth materials printed on translucent materials such as ultra-thin flexible silicon cells IBM ThinkPad T40 Battery possible.
Solar energy to put on body
If the technology will eventually lead to large-scale applications, will now generally fixed at the roof of the solar power industry with an alternative to stepped down from the roof as soon as possible. New type of silicon cells can be printed on the plastic surface of the volume, and create a variety of functions, can be printed on T shirt or other clothing, in the acquisition of energy when people wear.
Dr. Luo Jiesi and his team manufactured using standard printing such a silicon solar cell, the thickness of silicon less than the traditional process of one-tenth of the Laptop Battery. In addition, the battery array can muffle a pencil firmly, showing its flexibility is also very good. Technology has been licensed to Durham, North Carolina, (Durham) semiconductor companies Semprius, the company plans to launch in a year to manufacture the silicon cell module.
University of California at Berkeley (the University of California, Berkeley) and an assistant professor of electrical engineerJiewei Allison (Ali Javey) in the “natural materials” (Nature Materials) comment that the magazine, Rogers Dr. methods for large-scale the production of highly efficient solar cells and high toughness provides a new idea.
Traditional crafts manufacturing silicon solar cells rigid, heavy and opaque, but because of the stability characteristics of high-performance, as well as the inexhaustible resources of the silicon so that it continues to occupy the mainstream in the market IBM ThinkPad T41 Battery . But easy to brittle silicon ultimately limit the scope of its application. Dr. Jiewei said: “Dr. Luo Jiesi has solved a series of technical barriers, new technologies can be silicon or other inorganic substances in the interception of TLC and thin-layer attached to these other materials on the surface.”
The new silicon
Dr. Luo Jiesi and his team in the past 5 years has been engaged in research and development of flexible electronic components, this technology is nothing more than their follow-up results of previous studies. Dr. Luo Jiesi said they will first printing plate using standard thin solar cells will be installed to the semiconductor chip, and then seal with a soft rubber to other materials.
Dr. Luo Jiesi added: “The seal of the adhesive surface energy absorption from silicon IBM ThinkPad T42 Battery cells, you can imagine at this time into a silicon seal on the Latitude D620 battery of the ‘ink’, and then we seal the battery to other printed materials, such as this piece of plastic above. ”
Harvard University Professor of Chemistry and Chemical Biology, the famous chemist George Seitz (George M. Whitesides), said Dr. Luo Jiesi on the one hand, relying on the results of research in recent years, advances in silicon technology system, on the other hand, to overcome the large-scale application of silicon can not be the fundamental IBM ThinkPad T43 Battery defect.
He said: “The performance of silicon did not say, but previous rough rigid silicon production caused a lot of constraints. Dr. Luo Jiesi interception technology will be applied to inorganic silicon area of the system to overcome the traditional crafts produced by the lack of flexible silicon fundamental flaws. the new technology system not only to retain the traditional silicon technology, but also in related fields to lay the foundation for technological innovation. ”
The thinner the lower cost
Translucent silicon micro-batteries IBM ThinkPad R50 Battery will also have a number of characteristics of new uses, for example, can be stained as a power-type window paint, people can change the battery to regulate the density of the translucent windows. Coating on the more sparse cell density, the transmittance of the window, the better.
Durham, North Carolina in the factory, Semprius is solar arrays for the R & D technology and busy.Rogers CEO (Joe Carr) said new technology allows the company some of the many opportunities to cope.
The company is also to include the Motor Company’s potential customers, including R & D of photovoltaic modules. Karl said of the automobile IBM ThinkPad R51 Battery manufacturers to equip with new cells are very interested in the roof.
Dr. Luo Jiesi said: “The flexibility and transparency of these features is excellent, but the light is the biggest advantage of the new IBM FRU 08K8193 Battery. The cost of solar power is the greatest enemy of the industry, only the unit cost of power generation dropped to low enough, the solar power generation can be large-scale applications. new battery technology often only 2 microns thick (1 micron to 100 great 1 m), and you know, the more thin battery lower cost. “
