New Flexible Solar Cell

New Flexible Solar Cell

Recently, U.S. scientists have found an effective way of making silicon solar cells with sufficient flexibility, which allows it to wrap the object in the thickness of a pencil on top of or attached to the windows of buildings and even cars glass surface. October 5 issue of the "natural materials" magazine reported the results, saying the technology can be easily broken before the transfer to the flexible material on top of silicon, silicon slices for the traditional process provides new possibilities .

Of the study, University of Illinois at Urbana-Champaign, John Rogers, said the new technology will open the door to the promotion of solar buildings, "we can make it thin enough, then 'transfer' in a plastic chip, which to be curled into the system, so similar to the film thickness of the film can be attached to the glass surface of the building. "

It is understood that due to global warming and the impact of high oil prices, relying on photoelectric conversion of solar cells known as one of the most promising green energy. Including Japanese consumer electronics maker Sharp and Q-Cells of Germany, including many companies are making thin-film solar cell research and development related areas. But compared to conventional solar cells, thin film photovoltaic solar cell conversion efficiency lower the industry has been plagued problems.

Rogers said the technology is based on a higher photoelectric conversion efficiency of silicon as a raw material. Monocrystalline silicon wafers in order to overcome the shortcomings of a very brittle friable, they used a special etching method of silicon from a large cut on the silicon than the traditional 10 to 100 times thinner ultra-thin silicon . Different levels according to their thickness can be applied to different areas. When the wafers are cutting down, it will be a device to pick up, and then sealed as the general "transfer" to a new material above the surface. Finally, the re-use these as the electrical system of solar cells together into a whole. Compared with traditional solar panels, highly flexible solar cells that will be easier to transport and install. And Rogers is envisaged that the new materials will be like a blanket was thrown on the car.

"Batteries are not allowed to hide me," the new EU battery regulations

EU European Union in 2006 to promote cell program (Battery Directive), the destruction of the battery, recycling easier, and health programs, has recently been changed out. New battery program, which may include a change to some of the company's dumbfounded, that is: all electronic products must be easy to remove the battery, also known as "battery not allowed to hide me," the new rules.

This provision, it simply is to make users to an open end, a few loose screws to remove the battery can not make the steps easier recovery, but also are more convenient for users, and more willing to waste battery has a good resting place. In short, in addition to iPod / iPhone, the market there are a host of other electronic products in Europe if you want to survive in future, I'm afraid to use your head out!

Data theft at the cash

Data theft at the cash

With great effort and criminal energy unknown perpetrators have manipulated the world in wholesale credit card reader and collected the resulting data. In Britain alone amounts of damage, according to The Wall Street Journal at least 37 million "euros.

Are affected, according to Wall Street Journal wholesale markets in the UK, Ireland, Belgium, Holland and Denmark, including, for example, the chains Wal-Mart and Tesco. Incidents in Germany so far nothing is known. The captured data is sent directly from the Lesengeraten to Pakistan.

The procedure of the alleged criminals coming from Asia is sophisticated: In the credit card reader was installed several chips that allow reading and forwarding of wireless credit card information via mobile phone. The manipulation must be done before the sale to the supermarket chains, were prepared the devices in China.

not to attract attention, were also integrated mechanisms, the recordings only in certain intervals or only for certain types of cards. The Sniffer function was deactivated completely. To further camouflage the thieves used the data for two months after the read.

That the whole thing with so perfidious manipulation yet noticed, is due more to a coincidence. The radio produced a security guard at a wholesale market near a card reader noise. Alerted the police discovered the additional electronics in the reader and also a significant difference in weight of 100 grams compared with unmanipulated version. Using the modified device can be discovered.

Sony dashing in front of the E-Book

Sony dashing in front of the E-Book

On the subject of E-Book will work: At the Book Fair Sony today introduced its model, with which the Germans are to be supplied in future e-books. Now it is exciting. Which business model will bring his device Amazon Kindle in Germany on the market?

The book wholesaler, Libri is Sony's official partner in e-book. As the electronics giant announced today Libri will sell digital books from the spring of 2009 for the Sony Reader. The device itself will also be available at Libri, and in the bookstores in the Thalia Group.

At the start of the offer to thousands of digital books available to the prices is still not known. The books can be provided with a copy protection - similar to music - and it is expected that publishers make use of it also. A pass book is not at all or only with restrictions possible.

The internal memory of the Sony Reader holds 192 megabytes, which is sufficient, according to Sony for about 160 books. With an SD card or a Memory Stick, up to 16 more gigabytes available - room enough for thousands of books. Sony's reader will also open document types like PDF or Microsoft Word as well as images and music in the most common formats. 8600-times can the reader turn the pages before the battery must be recharged. This should allow browsing for days without power - Sony speaks of twelve novels on a single charge.

What is exciting now, as the market entry of the giants in the field will look like Amazon E-Book. The reader called Kindle and a mobile download service for Amazon in the United States is successful in the market and has also been the introduction of the Kindle in Germany announced.

Tokyo lurches into the red

Tokyo lurches into the red

To rest is to think not currently in stock markets. After yesterday already made new York and Frankurt middling business caught it again today, the stock market in Tokyo: It is located in a free fall.

The Nikkei index plunged by more than seven per cent and was only at 7864.18 points. One reason for the sell-off was the rise of the yen, which exports more expensive for Japanese companies. Wall Street had closed mixed yesterday evening after a trading day with strong fluctuations. The Dow Jones with 30 major titles climbed 2.02 percent to 8691.25 points, while high-tech stocks were less in demand. The Nasdaq has lost nearly one percent.

Sold today morning in Tokyo were mainly export-oriented company shares. Background of the appreciation of the yen in comparison to the dollar. The electronics giant Sony established its pessimistic outlook about the unfavorable currency ratio and the economy. Already yesterday, the Nikkei closed with a loss of 2.5 percent.

Even in Hong Kong today were recorded heavy losses: the Hang Seng index fell by more than four percent. In South Korea, the benchmark index fell for the first in more than three years under the mark of 1000 points. This represented a loss of 5.5 percent.

The economic downturn in the U.S., meanwhile, increasingly visible in the labor market. The number of applications for unemployment benefits rose after government data last week by 15,000 to 478,000. Starting at 400 000 is seen to reach a recession. The unemployment rate is currently 6.1 percent. In the 1991/92 economic crisis, it was 7.8 and in 1982 even more than ten percent. Among the companies that want to reduce the jobs include big names like Goldman Sachs, Xerox and Chrysler.
