Solar cells and Amorphous silicon thin film batteries

Solar cells and Amorphous silicon thin film batteries


Good prospects for solar cells, amorphous silicon thin film battery huge space for development


According to the American folk think tank, the World Institute and the Prometheus Institute to monitor the latest forecast predicts that by 2010, solar cell prices will be reduced by 40%, and a major power generation means.


World solar cell market in 2000, rapid growth after 6 times, in a single year of 2007 increased nearly 50% over the previous year. So far, Germany and Japan as the market center will be Spain and the United States. Silicon raw material shortage is the biggest problem, many manufacturers now have to reduce the cost of production in 2010 expected to be reduced 40%. As the silicon raw material shortages and price increases, promoting the efficient use of silicon technology and thin film amorphous silicon solar cells or the development, projected to reduce costs. Low-cost amorphous silicon thin film batteries up in less than photoelectric conversion efficiency, photovoltaic power generation in the future will occupy an increasingly important position.


A share listed companies can expand Nisshin (002 218) is dominated by amorphous silicon thin film photovoltaic chip manufacturers, we expect 08 to 10 years of its EPS for the 0.45,0.62 and 0.85 yuan, in 2008 corresponding to dynamic price-earnings ratio of 30 times. As the company's current valuation is high, we give its "neutral" rating, but we think long term, the company is worth focused attention.

iPhone3G battery life

iPhone3G battery life

If you do not have enough battery life, then the function of a cell phone, even then strong, in fact nothing but a Dragon of the technology. Therefore, popular in the Apple iPhone 3G handsets in battery life and standby time performance, naturally, many people paid much attention. According to the official publication of the data shows, iPhone 3G handset in standby time and talk time than the first generation of products is a marked improvement, Bingju in to achieve theoretically the 10 consecutive hours of talk time and 300 hours of standby time. So what is the reality of these? We take a look at this famous site PCworld specific test results conducted by it.



For the Apple iPhone 3G battery life in the performance of, PCworld mainly through 3G mobile phones and other similar cases in the same length of continuous talk time compared to the way to arrive at the battery life of iPhone 3G handsets are pros and cons conclusions. After and take the test, including Palm, Motorola, Samsung, Pantech Duo, AT & T Tilt, LG and HTC, etc. 10 to support 3G network, smartphone comparison, Apple's iPhone 3G the average talk time of 5 hours 38 minutes results become leader, its battery life than the other 9 kinds of 3G smart phones, ranked No. 1. Participate in the test in 9 of the 3G smart phone, only the Samsung Instinct, HTC Touch Dual and the LG EnV 3 phones of continuous talk time over 5 hours, which results Samsung Instinct and iPhone 3G closest, reaching 5.33 hours. HTC Touch Dual and the LG EnV were 5.18 hours and 5.04 hours.



As for the other to take the test of 3G smart phones are not continuous talk time of 5 hours, the worst performance of Palm Treo 750, or even continuous talk time less than 4 hours. It is worth mentioning that just opened at a time when 3G networks, 3G mobile phone standby time, once seen as factors impeding the development of 3G technology. In fact 3G network itself is a notoriously power-hungry, although 3G phones in the standby area has made great strides, but still with the expectations of the people there is a certain distance. In addition, it is also a 3G network technology, but AT & T operating WCDMA / HSDPA network and the Sprint and Verizon's CDMA2000 1X EV-DO network in energy consumption or there are some differences. Which, WCDMA / HSDPA networks as voice calls as data tasks are also through mobile broadband network transmission, so the power consumption relatively more. The Sprint and Verizon's 3CDMA2000 1X EV-DO network technology to transfer data only task, voice calls using regular CDMA network is, so in theory a number of more power. In other words, iPhone 3G use more power in the WCDMA / HSDPA network in the case, the performance of its battery life is still better than other phones, Apple Zheci speaks on the machine's battery life improvement is effective in .



Incidentally, is that for many users complained about the "paste and copy" and GPS navigation capabilities, Apple iPod and iPhone marketing Greg Joswiak, vice president of the explanation is still not on the "copy and paste" feature on the iPhone, Apple The functional development will have its own list of priorities, Apple has so far been strictly in accordance with the list of priorities to turn development. So, iPhone should be in future software upgrades to add "copy and paste" this feature. Second on the iPhone's GPS antenna has claimed too small to achieve route planning (turn-by-turn) navigation application functionality. Greg Joswiak pledge to continue to improve, and look forward to developers to make things that surprised us.

Britain developed a micro-engine is expected to replace the battery

Britain developed a micro-engine is expected to replace the battery

June 17, University of Birmingham announced that manufacturing and mechanical engineering university college lecturer, Chinese scientists led by Dr. Jiang Kaichun research group developed a micro-engine is only a few millimeters in size. Do not look at this small enough to be placed on the engine cover nails look like much, but the energy provided is 300 times that of ordinary batteries.

To understand the results of this study the situation, the reporter interviewed Dr. Jiang Kaichun.

About their research results, Jiang Kaichun showed great interest. He says that when they designed this engine's main purpose is to replace the traditional battery. Since the battery 发明, despite the miniaturization of electronic devices and portable and has played an important role, but the charge capacity of batteries is limited, so that electronic equipment Wei Liao continued work Bixujingchang replace or recharge in energy Persistence and Lianxu Xing Gong Ying there are some restrictions on gasoline and other fuels in this regard carbohydrates showed a clear advantage. In the development of the engine before they have specialized in different types of batteries and fuel were compared to results found in the weight of the same case, gasoline, hydrogen and other fuels to provide energy carbohydrates, 300 times the average for the battery. This means that the same is to supplement the primary energy, using micro-motor-driven device, battery-powered device than a much longer working hours.

In addition, it has been calculated to create the energy consumption of a battery than the battery itself provides 2000 times the energy of a large, if the processing of used batteries consider the energy consumption, then the battery life up costs. In contrast, micro-engine is much simpler, as long as it is added to a fuel, it can continuously work months or even a year or two. Not only eliminates the need for frequent battery changes or recharging the battery trouble, and the device itself could be more compact and lightweight.

On the engine design and manufacture, Jiang Kaichun said micro-engine manufacturing is very different from conventional engines. Conventional engine is usually full of noise produced by the plant in, but micro-engine is in the universities and research institutions in the clean room finished. They are now developing a kind of micro-internal combustion engine, this engine developed by U.S. scientists in different micro-turbine engine, the internal temperature is much higher. In order to withstand the engine running as high as 1,000 degrees Celsius resulting heat, they selected materials in the manufacture of alumina and silicon carbide. Both materials can be resistant to temperatures above 1,500 degrees Celsius, which was provided to ensure the safe operation of the engine.

As the micro-engine compact, and some internal components only a few microns, so the production process, they have adopted similar with the production of large scale integrated circuit technology. The difference is that required components do large scale integrated circuits as small as possible, but use the same process of production engines, you need bigger parts as possible. Because of fuel combustion in the engine requires a certain space, space is too small will not ignite the fuel, which requires the engine components to maintain a certain size. To achieve this, they use a lot of new technology. One of the most unique features is their "big thick layer of light plastic processing" technology. Using this technology, and now they have to process the material thickness is about 1 mm, which is very advanced world. In order to meet the needs of different devices, scientists can also output power of this engine to adjust. Approach is not a production of engines of different sizes, but the number of the same specifications as the engine output to connect different energy. For example, for mobile phones provide enough energy may be an engine, providing power for the laptop you need to put together a number of engines to work Caixing.

Micro-engine wide range of applications, in addition to mobile phones and portable computers can replace the battery, the military, medical and engineering manufacturing and other fields have wide applications. For example, with the increase in portable electronic devices, this should be traveling light soldiers will now have to carry more than 30 kg backpack in front of the war, including at least 1 / 8 load is designed to provide energy for the electronic equipment batteries. Some used for reconnaissance and liaison aircraft and micro-micro-robots as they have to carry heavy batteries and their role in severely affected. If these heavy batteries for micro-engines, their efficiency will be greatly changed. In the medical field, this engine also has a vast battlefield. Scientists, they can be installed in the diabetes and heart disease patients with medical devices, using them to provide lasting power, timing in vivo delivery of insulin for diabetics or people with heart pacemakers to provide energy. In addition, pharmaceutical, chemical manufacturing and processing, micro-mechanical components, this engine has great potential.

Therefore, Jiang Kaichun this engine is very optimistic about the prospects for development. He believes that this research is likely to first use the mobile phone industry. With the constant improvement of engine performance, six years later, the laptop computer and mobile phone battery will be gradually replaced by micro-engines, which will supply energy for portable devices have a profound impact.

Fuel cells and AuPt catalyst

Fuel cells and AuPt catalyst

Committed to fuel cell technology, efficient catalyst for innovation and advanced AuPt debut

Hitachi Maxell has developed a particle diameter of 2 ~ 3nm, and Pt (platinum) could result in unit area compared to about 4.8 times the current AuPt redox catalyst synthesis. At present, the solid polymer fuel cell air electrode (cathode) redox catalyst used generally to use more to carry on the carbon support on Pt catalyst.

Reduce the Pt particle size and increased surface area will help improve the catalytic activity, also add in the Pt Fe, Co and Ni and other metal elements can also enhance the redox activity. However, the problem is near the electrodes for fuel cells was strongly acidic, Fe and other metals dissolved in acid reaction in the power generation process prone to be dissolved away.

The Hitachi Maxell has developed a will not easily soluble in acid Pt Au added to the material. Difficult to form the alloy Au and Pt. Easy to grow into larger Au particles with the characteristics of hard synthetic particle diameter less than 5nm. The citric acid as a reducing agent, the temperature at 100 ℃ to the formation of Au and Pt AuPt alloy, developed only 2 ~ 3nm particle diameter of the catalyst. X-ray refraction analysis, confirmed that Au and Pt alloy structure is incomplete.

It is reported that the development of AuPt catalyst with Pt catalyst, in the standard hydrogen potential of 0.6V, the unit area was about 4.8 times the redox current. Hitachi Maxell that, Au and Pt alloy of incomplete structures and particles helps to achieve high activity.

Carrot and stick

Carrot and stick

The revamped S-Class is set to hybrid and more fuel efficient engines. The fact that the Stuttgart flagship for "Rainbow Warrior" mutated, is not expected. Is already secured by the newly revised versions of top-AMG and the mass-market U.S. and China. kd186 battery

When the new BMW 7 Series came on the market, the S-class suddenly looked very old. In terms of assistance and high-tech gimmicks, the Munich Stuttgart its competitors had overtaken the right and left. Now wants to strike back and make the revised Mercedes S-class as was the E-Class to a "thinking with whom the driver."

Presented were the new cars at the Shanghai Motor Show. There are a few visual retouching, for example at the grill and the headlights (now standard with bi-xenon technology), but above all a lot of new electronic helpers.

These include a high-beam assistant that varies the beam without blinding the oncoming traffic, a night vision system with pedestrian detection and lane-assistant. He warns the driver with vibration on the steering wheel when a lane marking without signaling runs over. tc030 battery

Lane Warner, there are also other manufacturers, but Mercedes wants a particularly sophisticated version developed: the electronics to detect whether the driver has inadvertently or deliberately left his trace. "The warning is not so if the driver accelerates, for example, before a passing maneuver or when driving on the highway when it brakes hard or directs in a curve," says Mercedes.

Also new is an "attention-Assistant is:" Does the electronics Lenkmuster unusual, it closes on a fatigue of the driver and chases a tone through the cockpit. Other high-tech helper is a system similar to BMW and Opel with a windshield camera reads signs and inform the driver in the jungle of signs on the valid speed limit.

The navigation screen is optional with a "SplitView equipped" technology. This driver and front passenger can have different functions: while the driver sees, for example, the map of the navigation system, the passenger on the same screen simultaneously watch a movie from DVD.

The main market for the new Mercedes S-Class is China. Not least because of the Swabians their automobiles figurehead at the Shanghai Auto Show for the first time presented to the public. "Nowhere else we sell as many S-classes, such as in China," says Ulrich Walker, Daimler CEO for the Asia Pacific region. Last year, China sold 14,000 S-class. hd438 battery

"Dreams about in China, any successful businessman. Only if you drive an S-class, one has "done it, says Lu Yuedi, successful owner of the real estate company Xidi as his marketing department that formation would have put into the mouth," In 2003 I had my first S-Class, S 350s purchased. Now I have a S 500, S 600, and two old S-class. "

Lu Yuedi is just 50 years old and is one of the league of self-made millionaires, the big cities like Beijing or Shanghai impress their mark in recent years. He also drives luxury cars from BMW and Porsche. But the day's work he performed alone in the back or at the wheel of his S 600 L.

The S-Class, together with its main competitors BMW 7 Series and Audi A8 luxury sedan in the upper ten thousand. Many are waiting for the new model and rub at the sight of the new model has the hands. "I will soon," still buy a S 65 AMG and Maybach, is proud to Lu Yuedi log as proof that his business is in the real estate world, seemed splendid.

In contrast, the S-class interest in Europe will focus on many of the diesel versions. In the United States are the top models S 550 4Matic, S 600 and the AMG models at a premium. From August, the new generation has to get with a hybrid drive. The ecological figurehead of the revised S-Class, the S 400 hybrid with lithium-ion battery that, according to factory specification achieved an average fuel consumption of 7.9 liters per 100 kilometers. lenovo thinkpad x60 battery

Interesting, especially for frequent travelers might be the S 350 CDI BlueEFFICIENCY (235 hp), which should be satisfied on average with 7.6 liters of diesel. Overall, the engine range include, in addition from the Hybrid eight gasoline and diesel engines, including the eight-cylinder Diesel S 450 CDI (320 hp), the base petrol engine S 350 (272 hp), the two eight-cylinder S 450 (340 hp) and S 500 ( 388 hp) and the top model S 600 with a 517 hp twelve-cylinder biturbo engine, with the luxury saloon accelerates in 4.6 seconds from 0 to 100 km / h.

The most powerful S-Class models, but as usual Affalterbach and listen to the names S 63 AMG and S 65 AMG. The V8 version brings it to 525 hp and a torque of 630 Newton meters, the sprint from 0 to 100 Km / h in 4.6 seconds. The S 65 AMG has a six-liter V12 engine with dual turbo under the hood and can come up with 612 hp and 1000 Newton meters of torque.

The acceleration from 0 to 100 km / h in 4.4 seconds. AMG trim, alloy wheels, double-end exhaust pipes and special daytime running lights mark the steam hammer with a star. That should please both S-Class-Fan Lu Yuedi.

The sports suspension, the AMG sedans equipped with a side wind stability. The work is varied within milliseconds by a wheel load distribution, drawing upon the yaw rate and lateral acceleration sensors of the ESP.

Further, a system called "Torque Vectoring Brake" is standard on board should: When cornering, a targeted short braking intervention at the inner rear wheel a "defined screwing" effect of the vehicle and thus allow more control in heavy cornering. lenovo x60 tablet battery

These systems are also available for the normal S-Class. The standard equipment of the two AMG-force air-conditioned hum sports seats, leather upholstery and a seven-speed automatic (five-speed automatic includes the S 65 AMG). The S 63 AMG is with a long or short wheelbase, the S 65 AMG long version only.
