    U.S. Dow Chemical Company (DOW-US; DOW) recently announced that they will set up renewable energy sector. And will work with First Solar (FSLR-US) launched a solar energy competition.
    “TheStreet.com” reports, Dow said in a press release detailing the new products will be combined with roof tiles and solar, and said, traditional roof tiles also install this new technology, and a new roof tiles tablets will not have any impact on the house.

    Dow said that these roof tiles using PV systems (BIPV) materials, the use of high-performance copper indium gallium selenide (Copper Indium Gallium Selenide, referred to as CIGS) thin photocell batteries at the end, and the composition of the traditional processing methods Mezzanine.

    Dow did not disclose the source of CIGS cells, after all, they already have their own ability to develop the material, but it is also possible that development of CIGS to other companies that purchased. These companies include Nanosolar, Global Solar (TAN-US), MiaSole, HelioVolt. This four companies are private companies, but only Global Solar full-scale production CIGS products.

    More than a year ago, IBM announced a partnership with Tokyo Ohka Kogyo co-development of copper indium gallium selenide technology, a joint venture case, and may in 2010 or 2011, the company licensed to solar energy. With the target of production of solar cells the cost of electricity caused by pressure less than 1 dollar per watt. This solar energy technology is a long-term goal, and will increase the efficiency of solar cell business, 15%, at present the efficiency of markets in the region of 10%.

    HelioVolt announced plans to achieve 12.2% efficiency, while the Global Solar said it expects eventually to reach 14% efficiency.

    In theory, these efficiency goals are feasible. In 2008, the U.S. National Renewable Energy Laboratory in the use of conventional techniques, had reached 19.9% efficiency.

    First Solar was widely regarded in the industry’s efforts are leading to other companies. Earlier, before First Solar announced that it will raise target 1 U.S. dollars per watt cost of manufacturing products.

    According to the workers reported, with the fifth generation of large-scale mass production of thin-film batteries, one of universal application of the coming age of solar photovoltaic power generation, solar power will be like food, drinking water as readily available, solar power will become a check was not done to do, inexhaustible, clean and environmentally friendly alternative sources of energy, it is Johnson & Johnson, director of Cheung Sha Xiaolin photoelectric April 15 at a press conference to describe a beautiful scene.

    Whether the popularity of solar power is the key cost, Nantong, Johnson & Johnson Optoelectronics Technology Co., Ltd. and the United States the third-largest known vacuum equipment manufacturing companies co-develop, improve and create a new thin-film hp pavilion dv8000 battery,hp pavilion dv9000 battery technology, the core equipment, and with the the relevant research institutions and multinational cooperation in development and production of laser-engraved lines matched, laser to the side of the key equipment such as vacuum sputtering, so that the entire production line of sophisticated, advanced in the world’s leading position. Not only the conversion efficiency of thin-film batteries in one fell swoop more than 6.5%, to reach the world advanced level, and the equipment cost is only 25% of similar imported equipment, so that to reduce the cost of solar power become a reality. 

    Sha Xiaolin view, 1.1 × 1.4m area, the fifth-generation thin-film battery, whether it is for the manufacture of thin-film hp pavilion zd7000 battery,hp pavilion zv5000 battery devices, or thin-film battery components production, are one of the best specifications. Currently, Johnson & Johnson photovoltaic thin-film battery production lines and core equipment, are used as criteria for the same time through further development and improvement, the equipment is more advanced, cost of similar imported equipment should be reduced to the price of 20%.

    “The ultimate in two years and a half to make photovoltaic electricity price per unit fell to 0.65 yuan, close to the cost of thermal power generation to meet the popularity of solar power era.” Sha Xiaolin, said Johnson & Johnson put into mass production of photovoltaic current or the world’s first single-chip does not require laminated packaging film batteries, it is precisely this has been in nearly 60 countries, patent applications for new technology to make thin-film compaq evo n400c battery,compaq evo n410c batterycomponents of the weight of a whole “diet” 50%, the popularity of solar energy batteries in buildings to create the best conditions for the application. In the future, the building’s glass curtain wall, roof can be replaced with thin-film batteries, which means that the building itself will be able to generate electricity. 

    Currently, Johnson & Johnson has been completed photovoltaic plant in Nantong three production lines and has been put into mass production, production capacity reached 100MW, this capacity can enter the world’s fifth-generation amorphous silicon thin-film compaq evo n400 battery,compaq evo n410 battery production facility before the 5. The company plans to again this year on three production lines, production capacity reached 200MW, next year on the nine production lines, to the end of 2010, production capacity reached 500MW, to become China’s largest production base of amorphous silicon thin-film batteries.
