Commercial exploitation of solar cells
Currently, Dell Latitude D420 Battery there are at least 40 countries are carrying out the next generation of low-cost, high efficiency thin-film solar cells for practical research and development.
Last year in October, Japan, Showa Shell Oil hit a copper indium selenide thin-film photovoltaic conversion efficiency of solar cells the highest world record. Area of 864 square centimeters of the conversion efficiency of 14.3%, an area of 3560 square centimeters of the conversion efficiency of 13.4%. As the company has made use of the solar cell Japan’s first 10-kilowatt solar power system, so that the practical application of solar cells a major step forward.
Copper indium selenide thin film solar cells can be realized cost-efficient, with less than the current mainstream because of its crystalline Si solar cells the cost of the Department of competitive advantage, is expected as a next-generation solar cells. In addition, copper indium selenide thin film solar cell tolerance to the cosmic rays than other batteries is high, a low-cost, light weight of the universe, solar cells, can be used as satellite power supplies.
Reduce the production cost is the Dell Latitude D430 Battery key to the promotion of solar cells. German Solar Energy Research Institute after 10 years of hard work, developed a new type of thin-film solar cell technology, the technology uses a continuous electro-deposition process, the copper foil was prepared to form thin-film solar cells with a volume, and then a special assembly packaging process into the soft solar modules. At present, this battery has reached 9.2% efficiency in laboratory and theoretical efficiency of up to 30%, and because less material consumption, simple process, the final cost is expected to be lower than 0.6 euros per watt.
Thin-film solar cells involved in the automotive industry with Dell Laptop battery
Japan’s third-largest car maker Honda Motor Co. announced last December 19, from 2007 started mass production of solar cells, the company will Kyushu Kumamoto factory cars again in the establishment of a factory specializing in the production of solar cells, Once the new plant production capacity to achieve the desired 27.5 megawatts, enough to meet 8000’s daily electricity needs of the family, then a year from the sale of solar cells to obtain 70 million U.S. dollars in revenue.
Although Honda has not publicly produced the materials used in solar cells, but industry insiders believe are using does not contain silicon, copper indium selenide (CIS) thin film, such solar cells from the early 20th century, 80 developed in polycrystalline thin-film Dell Latitude D500 Battery. CIS cell with its low-cost, high efficiency monocrystalline silicon solar cells close to the stability and strong anti-radiation of the space to become this century’s most promising solar cells is one of the many research institutions at home and abroad and industry experts hotspot. And made of silicon as the raw material compared to conventional solar cells, copper indium selenide thin films in the production process of the energy consumed is only half of the latter, but also a corresponding reduction in carbon dioxide emissions by 50%.
China’s rapid development
China’s independently developed the “copper indium selenide thin film solar cell test platform with the pilot line” project, has been of Science and Technology as a national “863″ plan a new research topic.
Copper indium selenide thin film solar cells with glass or other low-cost substrate materials, the metal compound film thickness is only 3 to 4 microns, its photoelectric conversion efficiency higher, while low resource consumption, little environmental pollution.
Currently in a number of major breakthroughs in key technologies and the creation of the battery photoelectric conversion efficiency of more than 12% of the new record. The project is scheduled to be completed by the end of 2006 will see the compounds, thin-film solar cells Dell Latitude D520 Battery that China’s high-tech living in the international advanced level, and make the product as the most promising thin-film solar cell market is one.
