    Fehrenbach Bosch: the introduction of the lithium battery system should be more careful

    Electronics No Comments

    October 13, Bosch Group Run Bach Franz (Franz Fehrenbach) came to Beijing. Decline in the volatility of the global economic environment, Fehrenbach is still optimistic about China. He announced that in the next three years,pa3191u-1brs,pa3191u-2brs,pa3191u-3brs,pa3191u-4brs, the Bosch common-rail diesel system will be operational in the field of 200 million euros of additional investment.

    Reporter: This year, many multinational companies are faced with economic hardship, how to maintain a rapid growth of Bosch?

    Fehrenbach: Many people have said that major global companies in the world will be bound to disappear. But I do not see, the DNA in the Bosch, the continuous technological innovation and investment in research and development and stability is to maintain the vitality of the two important factors.

    Bosch’s annual R & D investment in more than three billion euros. And in the automotive field, Bosch has 10% of sales for R & D investment will not be the global economic downturn and the economic slowdown and the reduction in R & D inputs.

    In addition, Bosch is also the company’s ownership structure to ensure financial independence and entrepreneurial freedom. As we all know, 92% of the Bosch Group, owned by Robert Bosch Foundation held to ensure that the company’s revenue and the interests of shareholders.

    Reporter: Asia-Pacific region this year, Bosch’s business growth and how? How do you see the future of Bosch in the development of business in China?

    Fehrenbach: Bosch in the world this year is expected to reach sales of 47 billion euros, of which the Asia-Pacific region’s business growth is the main driving force Bosch, pa3128u-1brs,toshiba portege m200 battery,toshiba portege m400 battery,Bosch’s Asia-Pacific operations accounted for about 16% of global business is expected to increase by 2015 to 25%.

    Bosch 2008 sales in China will reach 2.3 billion euros (about 25 billion yuan), an increase of 30%. It can be said that without China’s growth, there will be no growth of Bosch. Although the Chinese market is currently in a cyclical period of adjustment, but we are still optimistic about its prospects for development.

    Reporter: Bosch in spending huge sums to acquire a German company for electric vehicles, may I ask how you look at the new prospects for the development of automotive energy?

    Fehrenbach: Bosch is the phases of view: from now to 2020, mainly to reduce carbon dioxide emissions and improve energy efficiency of the combustion engine; in 2020 after the year is the development of hybrid vehicles, electric vehicles will be followed by the mainstream market.

    In the development of battery technology, I believe that lithium-electronic technology is only a start, the battery technology needs to be a long way to go. Bosch hopes to enter the core area of battery technology, to that end, choose Bosch battery technology in a lot of experience as a partner of Samsung. We plan for the automotive industry in 2012 to provide car battery.

    Now, we are very careful attention to the major manufacturers of electric vehicles in the field of action, some manufacturers quickly introduced a lithium battery car electronics. In our view, it seems this is not safe, because if the event of a major security incident occurs, would mean the end of this technology. Therefore, we also remind you that the introduction of the lithium battery of electronic public transport system or other vehicle systems should be more careful.

    Reporter: Bosch and Mahle joint venture to build production turbocharged engine company in 2009 and plans to accept orders in China. But China’s current sales of turbocharged models and not more than, how China’s development in this regard?

    Fehrenbach: At present the international market 50% of diesel vehicles in the use of turbochargers, turbocharger can be said that in the use of diesel cars have become so widespread that the future is to see turbocharged gasoline engine in context use.

    As a result of environment and energy policy in a more urgent requirements of the traditional internal combustion engines to reduce emissions and save energy. Currently in the United States, 6-cylinder engine is replaced by 8-cylinder engine; in Europe, 4-cylinder engine 6-cylinder engine was replaced. At the same time, batcl50l,acer travelmate 290 battery,dell xps m1530 battery people driven out of the requirements of the engine on an essential requirement for the installation of a turbocharger or two. Because we believe that the development of turbochargers very good prospects. I believe in China as well.

    In the nano-column grown on aluminum foil can produce solar cells

    Electronics No Comments
    U.S. researchers developed a new type of solar cell technology, solar cells that can grow in the aluminum upright to the nano-column is made of the entire battery is packaged in a transparent polymer gel can be produced inside the can after the Bending the solar cells, cost less than traditional silicon solar cells.
    The study of the leadership of the University of California, Electrical Engineering and Computer Science Professor Alijawaysaid that with the traditional silicon and thin-film battery as compared to nano-column technology will enable researchers to use more low-cost and low-quality materials. More importantly, the technology is more suitable for the production of thin aluminum foil that can be curled on the solar panels, thereby reducing the manufacturing costs. Once successful, the production cost will be single crystal silicon solar panels can be as low as 1 / 10.
    This solar cell will be uniform through the 500 nanometer high embedding CdTe CdS thin films made of these two materials are often thin-film solar cells use semiconductor. Morrison and his colleagues in the “natural materials” published in the report, such a solar cell will be converted to electrical energy efficiency of up to 6%. Prior to this, dell latitude d510 battery , dell latitude d520 battery scientists also use the design idea of this column, but more expensive method, and photoelectric conversion efficiency of less than 2%.
    In traditional solar cells, the silicon to absorb light and generate free electrons, the electron must be trapped in defects or impurities in the material before the arrival of the circuit. This requires the use of very pure, expensive to manufacture high-performance crystalline silicon photovoltaic devices.
    Nano-column assumed the duties of silicon, nano-columns around the optical absorption and produce electronics, nano-columns will be delivered to the circuit. This design in two ways to improve efficiency: a close package of the nano-columns between the columns to capture light, the surrounding material to help absorb more light; e to a very short distance across the nano-columns,  dell latitude d600 battery , dell latitude d610 battery,not too many opportunities by defects in material hardship. This means that you can use low-quality low-cost materials.
    Scientists use a different nano-structure to the production of such solar cells. For example, a chemistry professor at Harvard University, Charles Boer R & D that contains a silicon core and concentric layers of silicon nanowires different; the University of California at Berkeley developed  while zinc oxide nanowires with the dye-sensitized solar cells . These nanowire photovoltaic solar cells have achieved conversion efficiency of 4%.
    Morrison and his colleagues produced the first nano-column cells using the oxidation of aluminum foil, creating a cyclical distribution of the 200 nm wide holes, these holes as the vertical growth of CdS crystal template. Then, cadmium telluride and the top electrode decorated with copper and gold films. Through a glass plate and pa3383u-1brs,toshiba satellite a70 battery connected, or polymer solution into the top to bend.
    Georgia Institute of Technology professor of materials science and engineering, said Zhong-Lin Wang, the nano-materials engineering design and manufacture flexible high-performance flexible solar cell technologies in a variety of soft substrates together, this is an exciting progress. U.S. National Renewable Energy Laboratory study of solar cells is responsible for the physical chemist Popieluszko Arsenault said that this battery with the silicon, cadmium telluride and other flexible materials to compete with thin film solar cells, and its selling point may not be its flexibility, but the cost advantage.
    Currently, researchers are exploring the use of the materials to improve conversion efficiency. For example, the top of the copper - gold layer is only 50% of the transparency, if all the light through, and its efficiency can be doubled. Therefore, researchers are planning to use such as indium oxide transparent conductive material. In addition, the use of other semiconductor materials as nano-column and the surrounding materials researchers are also taken into consideration, so that the production process can be suitable for a wider range of semiconductor materials,toshiba satellite a75 battery,toshiba satellite p30 battery,toshiba satellite p35 battery, other material combinations may also increase efficiency, a more important point is cadmium toxicity can be avoided the issue.
