Fifth-generation large-area thin-film battery in China

Friday, April 24th, 2009
  The article come from http://www.batteryoffice.com
With the fifth-generation large-area thin-film battery volume production, one of universal application of solar photovoltaic power generation era, solar power generation will be like food, water everywhere, as available, solar power will become inexhaustible, do not use dried up, clean environmentally friendly alternative sources of energy, it is Johnson & Johnson, director of Cheung Sha Xiaolin photoelectric April 15 at a news conference to describe a beautiful scene.
Whether the popularity of solar power generation cost is the key, Nantong Optical Technology Co., Ltd. Johnson & Johnson and the third largest U.S. manufacturer of vacuum equipment co-operation in research and development, improvement and manufacture of a new thin-film battery technology, the core equipment, and relevant research institutions and multinational cooperation in supporting the development of production line of laser engraved, laser to the side of the key equipment such as vacuum sputtering, so that the entire production line of sophisticated, advanced in the world leading position. Not only the conversion efficiency of thin-film battery in one fell swoop more than 6.5%, to reach the world advanced level, but similar devices cost only 25% of imported equipment to reduce the cost of solar power become a reality.
Sha Xiaolin that, 1.1 × 1.4m area of the fifth-generation thin-film batteries, thin film batteries for both the equipment manufacturers or the production of thin-film battery components are one of the best specifications. Currently, Johnson & Johnson film photovoltaic cell production line and core equipment, are used as criteria, and at the same time through further development and improvement, so that more advanced equipment, the cost of similar imported equipment should be reduced to below 20% of the price.
“The ultimate in two and a half years to make photovoltaic electricity price per unit fell to 0.65 yuan, close to the cost of thermal power, the popularity of solar power generation to meet the times.” Sha Xiaolin, said Johnson of the photoelectric mass The first piece of the world do not need to package the single-layer laminated film batteries, is this in nearly 60 countries to apply for patents for inventions of new technology, so that the weight of an entire thin-film battery components of the “trimming” of 50% for the popularity of solar energy battery applications in buildings to create the best conditions. From now on, the curtain walls of buildings, the roof can be used to replace thin-film batteries, which means that buildings will be able to generate electricity.
Currently, Johnson & Johnson photovoltaic plant in Nantong, has been completed and three production lines have been put into mass production, production capacity reached 100MW, this production can enter the world’s fifth-generation amorphous silicon thin-film battery manufacturing plant in the former 5. The company plans to again this year on three production lines, production capacity reached 200MW, next to a nine production lines, to the end of 2010, production capacity reached 500MW, has become China’s largest production base of amorphous silicon thin-film batteries.

SSD power savings to meet the needs of a country

Friday, April 24th, 2009
According to iSuppli Corporation, from 2008 to 2013, solid-state drives (SSD) for data centers around the world to save a total of 166,643 megawatt hours (MWH) of electricity, laptop battery according to the U.S. Energy Information Administration (EIA) statistics, slightly higher than in 2006 Gambia, the country’s generating capacity a year.

SSD can replace the use of data centers 10% of the high-end and high-speed hard drives (HDD), these “short-stroke” hard drive for fast read and write only transaction data, rather than for storage.

15000RPM speed for each of the SCSI (SAS) hard disks each day about 14 watts of power consumption. HDD and SSD only half of these, about 7 watts. Saving 50% is a considerable sum Latitude D520 battery , Latitude D600 battery , Latitude D610 battery , it is not an SSD in the enterprise data center used to be a small amount, but also save a lot of power.

2013, the number of energy saving is expected at the time from 2008 to 6986 MWH growth 57564 MWH, a total of six years can be saved down 166643 MWH.

It provides global data center in the enterprise server SSD can be used in energy-saving projections. However, these “short-stroke” HDD only the hard disk during the forecast period the overall global shipments of about 5%. If the storage Latitude D620 battery market completely avoid the use of HDD rotating machinery such as media move to SSD, it is expected for 2008-2013 energy savings may be iSuppli forecast 20 times.
   SSD into the enterprise data center is very conducive to energy conservation, Latitude D800 battery in the near future to replace the hard part of the short stroke.
