VS hybrid fuel cell vehicle
The continuously rising oil prices, fuel tax policy is also imminent dell latitude d620 battery, pc764 battery, tc030 battery, saving has become of paramount importance to the community as a whole. The government and consumers to encourage a rational look at, small displacement cars and energy-efficient cars are also welcome its spring overnight.
At the same time, the new energy automotive vehicle as the main future direction of development, but also the ultimate solution to the issue of energy measures, but also increasingly by the Government and the manufacturers attention. National Development and Reform Commission and other departments are organizations to develop “” Eleventh Five-Year “ten key energy-saving project implementation plan.” Among them, the clean cars, alternative fuels and automotive fuel-efficient technology will become the “Five” savings and an important alternative to petroleum engineering content. And many vendors have started to put on the new energy vehicles for mass production of the agenda, perhaps the near future they will be flying into the home of ordinary people.
Of these, hydrogen-powered, zero-emissions can be achieved, so far not been achieved commercial fuel cell vehicles, and electric motors with internal combustion engines and hybrid-driven series, has been the successful implementation of commercial hybrid cars become the new energy vehicle development direction of the two major .
Hybrid Electric Vehicle
It is learned that the first hybrid electric vehicle has completed the development of national standards dell latitude c600 battery, dell latitude c610 battery, dell latitude c640 battery, the standards for a total of six, will be October 1, 2005 into effect. The first batch of six criteria, including hybrid electric vehicle test stereotypes in order and hybrid electric vehicles, such as security requirements, the first national standards for hybrid sales in the domestic production cleared the biggest obstacle. At present, have successfully developed a hybrid electric vehicle research and development of a red car like a hybrid vehicle, the Chang’an Automobile CV9-like vehicle, and FAW Toyota Prius production has entered the final stage of preparation, is expected at the end of the listing.
South Korea developed a solar energy battery sheet
According to the South Korean “Daily Economic News” reported on the 18th, South Korean scientists successfully developed a solar energy 75uyf battery, 1691p battery, dell inspiron 2500 battery, dell inspiron 3700 battery, dell inspiron 3800 battery sheet. This thin flexible batteries will become a new generation of mobile communication terminal supporting power supply.
Korea Electronics and Telecommunications Research Institute scientists develop thin battery such as fuel sensors solar cells, shape like a piece of paper, a half of A4 paper so much. This cm2 area of each cell can generate 4.8 milliwatts of electricity, which is so far the highest power-generating capacity of solar cells fuel sensor.
This solar battery plate characterized by the largest bending function. It is a plate made of stainless steel, the other side of the use of plastic materials, can be bent. The future, wearing a watch-type computers and computers came a new generation of mobile communication terminals, this solar cell plate can be attached to clothing or bags to provide power.
Copper indium selenium solar cell projects funded by national 15,570,000 yuan
Professor Sun Yun from Tianjin Nankai University presided over the “copper indium-selenium thin film solar cells in the test platform and test-line” project, Ministry of Science and Technology has been a national issue 863 new projects, and 15.57 million yuan of funds to support the roll has become this times the area of domestic energy technologies available to the new issue of the project the maximum amount of grant projects.
Copper indium-selenium thin film solar cells with glass or other low-cost substrate materials, metal compound film thickness is only 3 to 4 microns, and its photoelectric conversion efficiency, and low resource consumption, less environmental pollution. Professor Sun Yun Nankai University and through the organization of joint research group has been in a number of key technologies have made a major breakthrough, and has created a battery-electricity conversion efficiency higher than 12% of the new record, one among the research areas in the world of the first four name. The project is scheduled to be completed by the end of 2006, the will of our compound thin film solar cells of high-tech living in the international advanced level, and the product has become the most market potential of thin-film solar cells.
Development of the “dirty silicon” technology to produce new low-cost solar cell
University of California, Berkeley researchers announced the development of a based on the “dirty silicon” (dirty silicon) of the new technology, this technology can reduce the cost of solar cells dell inspiron 4000 battery, dell inspiron 4100 battery, dell inspiron 4150 battery, dell inspiron 8000 battery, dell inspiron 8100 battery. Nearly 90% of the solar cell is due to refining of pure silicon production.
The use of such a richer, cheaper silicon – that is, the existence of metal impurities and defects in silicon – the attempt has not been successful, because the use of this material can not be produced by solar cells to run. In addition, for the elimination of impurities in the high cost of manufacturing techniques, the use of cheaper materials to offset the cost advantage. Berkeley professor of materials science, Weber said: “We propose the use of dirty silicon, a new method.” Weber said: “We are not to remove impurities, but left them, but through a reduction in their adverse effects on the solar cell approach to take advantage of them. ”
The researchers said their study found that will enable more low-cost waste into useful materials, reducing the cost of solar cells. Researchers can detect the use of only 30 nm high-sensitivity metal cluster synchrotron X-ray microscope, an analysis of the metal impurities in silicon for different types of reaction processes. The researchers found that the distribution of silicon material in different locations on the nano-scale defects in limiting the energy loss of electrons can be spread before the average distance. Dissemination of the longer distance, the material on the higher energy conversion efficiency. The researchers found that by changing the cooling rate of silicon to control the distribution of metal impurities. Slow down the cooling rate, the proliferation of metal impurities in the formation of large clusters, thus changing the distribution of impurities dispersed.
U.S. R & D 1.2 billion U.S. dollars for the use of hydrogen fuel-cell vehicles
Mack, vice minister of the United States Department of Energy in the history of Bolero, a Washington energy conference that the United States is seeking to diversify energy sources, including President Bush’s vision of the hydrogen economy is one of them. President Bush has proposed in a speech to 1.2 billion U.S. dollars into research and development use hydrogen fuel cell vehicles. History Mike Valero said that the United States the benefits of the development of hydrogen energy economy is the large scale use of domestic resources to produce, do not need to rely on the same oil as imports from other countries. For pollution-free, no need to transport solar energy, more confidence in the development of the United States is an ambitious one. By 2010 the United States dell inspiron 8200 battery, dell latitude c500 battery, dell latitude c510 battery, dell latitude c540 battery would install one million solar roofs family.
