U.S. scientists develop a low-cost plastic solar cells
University of California, Los Angeles Campus (UCLA) researchers have developed a low-cost plastic solar cells, solar cells that will be the production cost of traditional solar cell production costs by 10% ~ 20%. At present nearly 90% of the solar cells are made from silicon, and from UCLA to develop solar cells dell inspiron 5160 battery,dell inspiron 6000 battery is between two conductive pole holding a plastic composed of single-layer. UCLA engineering professor Yang Yang pointed out that such a solar cell conversion efficiency of 4.4%, which is far the world’s highest conversion efficiency of plastic solar cells. The conversion efficiency of solar cells to absorb all the radiation refers to the surface in the percentage of total energy.
According to UCLA, said the performance of plastic solar cells is the ultimate goal of conversion efficiency reached about 15% to 20%, and the use of period 15 ~ 20 years. As for the traditional large-scale solar cells for use in the same period of the conversion efficiency of 14% ~ 18%.
Make greater efforts to develop fuel cell industry
Jiangsu Provincial People’s Political Consultative Conference member Xu Jian Zhang: fuel cells with high efficiency, environmentally friendly, quiet and high reliability in the future hydrogen economy era, the core of the emerging industry chain, will reduce dependence on oil imports, to protect national energy security and reduce the greenhouse effect, to improve the quality of the environment . Recommendations to improve policies and regulations, the development of renewable energy development and utilization of long-term goal, to increase financial subsidies and tax concessions.
Olympic bus “favor” made nickel-hydrogen batteries
A few days ago, the Beijing Municipal Government established in the domestic procurement for the Games at least a few thousand electric vehicles buses, cars and athletes as a shuttle bus program, “the Olympic bus dell inspiron 630m battery,dell inspiron 6400 battery power,” the procurement project team has sights on leading technology and world-class performance Chunlan momentum of China-made nickel-metal hydride battery.
The market may choose to use the power batteries are lithium batteries, zinc-air batteries, fuel cells and nickel-metal hydride batteries, but lithium, zinc, and other new energy sources, fuel cell industry chain in the industrial and practical applications are still many problems, and Chunlan power Ni-MH battery pack and power management systems, 863 have passed the national electric vehicle acceptance of the third round of major projects and a large number of application of large-scale machinery, power tools, robots and FAW, Dongfeng production hybrid city bus.
Battery is the key to buy mobile products
In the near future Sina IT168 website and a joint investigation of the laptop showed that nearly 50% of the users to “extend notebook battery life” issues as a first choice. The manufacturers usually focus on what the recommended hard disk transfer rate of 5400, 1394, Bluetooth, 802.11 wireless, Gigabit LAN what, but all in a simple “battery life” behind.
This has given the answer to the so-called experts have a lot of the glasses below. Why is there such a result?
For desktops, the performance may be the vitality of the host desktop; As for notebook computers, the battery life is the life of notebook computer power. Simply consider the configuration of the desktop experience in a notebook is no longer fit the times might have been.
ASUS has been with leading motherboard manufacturers, such as technology, as well as a number of notebook Power4Gear industry-leading power technologies, M2N its new products in the standard configuration has been reached in 7.4 hours time. During the interview, ASUS engineers said that many manufacturers currently on the market are always in the promotional products advertised high configuration, in fact, these are induced by a non-comprehensive. In actual use, the same configuration, the performance of notebook computers will not be stronger than the desktop, if the pursuit of simple configuration options so not as good as the desktop. From practical applications, the notebook computer from the desktop should be the biggest advantage of portable and mobile. Based on this principle, ASUS laptop in the design to take into account the two most important factors is the “thin and light portable and lasting power.” A lack of long-lasting battery life of notebook computer capacity, it is impossible to take a long time the needs of mobile applications. And the lack of dell inspiron 5150 battery,dell inspiron 5160 battery power of notebook computers to help, and naturally the most fundamental lack of vitality.
It is based on a unique application of notebook computers fully into account, it always insists on ASUS notebooks focus on the power-saving technology to do one of the technological development. Currently, Asustek’s notebook computers are basically used Power4Gear original ASUS power switching technology. The technology uses a microprocessor and a number of deep-sleep standby set performance greatly enhanced notebook PC features the use of elastic energy.
From the development of notebook computers, the Centrino technology is the future direction of the development of notebook computers. And to provide more long-term Centrino technology is the use of the time one of the key points of concern. According to Intel Centrino in the time of the promotion of a survey conducted by the current users of notebook computers to provide wireless connectivity and more time using the most concern. In more time, how to reduce the notebook’s power consumption, increased use of mobile computing time for those who are even more important. In fact, both the practical applications of notebook computers or the future direction of development, we can no exaggeration to say that the battery life of notebook computers is the driving force. Notebooks should be to ensure that the basis of a lasting power to provide dell inspiron 6000 battery,dell inspiron 630m battery the most suitable applications.
