According to Kyodo News, Japan’s third largest solar cell manufacturer Sharp, Kyocera, Panasonic’s 2011 fiscal first quarter (April to June) report showed that sales of solar cells than with flat or decline over the same period last year.

Andy Sharp, vice president Toshio pointed out by the East Japan Fukushima earthquake and the impact of the first nuclear power plant accident, natural energy to get attention, so “the domestic market remain strong.” However, falling prices in overseas markets and other factors have a negative impact.

Kyocera solar cells just as the core business to achieve sales growth of 1.3%. Society has long fang Tetsuo pointed out that in the solar power system has been popular in Europe, the acquisition market, “price fell.” Fong also said a long time, the price of solar cells “from a year earlier, down 2 percent over.”

The output power as a basis of sales, the Sharp is about 260 MW, with the year-ago quarter, but sales declined 10% to 51.3 billion yen (about 4.27 billion yuan). Although Matsushita’s sales increased by only 2%, but the real Wild on the Managing Director emphasized that “to maintain profitability.”

“Shanghai Institute of Ceramics, Chinese Academy of Sciences - Sony lithium battery joint laboratory” in Shanghai on July 14 opening. Shanghai Institute of Ceramics, and Sony, respectively, in sodium-sulfur battery and lithium-ion battery development has accumulated a wealth of experience, joint research laboratory will be the next generation of battery technology, to develop a similar energy density of gasoline the car battery.

According to the Joint Laboratory Guoxiang Xin, deputy director of the Chinese researcher, the main advantage of the next generation of lithium batteries as large energy storage battery energy density can be increased compared with the previous battery 5-10 times. As the energy density of gasoline is similar to the next generation of lithium batteries is expected to solve a new generation of green vehicles - electric cars energy supply. In addition, next-generation lithium battery also has a friendly, high-power, long life and many other advantages. At present, the next generation of lithium battery research and development is still in the basic research stage, the need to address the battery power density, cycle stability and other issues, the application of new technologies into the market take some time. The “lithium Joint Laboratory” is enabled, Shanghai Institute of Ceramics, and Sony will make full use of both technology and talent resources to actively promote the development and application of the next generation of lithium batteries.

It is reported that as early as 2005, Sony Corporation and the Shanghai Institute of Ceramics, which signed the first joint research project contract of carbon nanotubes in 2007, Shanghai Institute of Ceramics, the two sides established a solar cell as the main object of study, focus on new materials development and application of energy the first joint lab in the new energy R & D has achieved good results.

International rating agency Standard & Poor’s predicted that China’s solar battery panels manufacturers will increase market share, which is due to overcapacity and weak prices have forced the closure of foreign competitors or seek mergers.

Standard & Poor’s credit analyst Swami Venkataraman said in a research report, such as Yingli Green Energy Holding Company Limited and Trina Solar Limited and so benefit from the government-backed China manufacturers are lowering the price of photovoltaic panels, compressed margins, face higher costs in order to put pressure on European competitors.

He said that China has become the leading producer of solar panels. High-cost, single-panel manufacturers out in the next few years become a necessity, unless the demand surge and allow all producers to thrive.

However, Venkataraman said, Arizona’s First Solar is likely to remain the market leader, because of its cadmium telluride thin film solar cells cost polycrystalline silicon solar panels made in China at least 30% lower than .

He said that even if the polysilicon prices decline below the current spot price of 50 U.S. dollars / kg, compared with the first solar energy companies are still the lowest-cost Chinese manufacturers have a distinct advantage.

July 7 news,a team of British scientists announced Monday they have developed a new type of plastic solar batteryies. This product not only can replace silicon as the raw material of conventional solar panels, but also in the price than the latter is much cheaper. They expect such products in the next five to 10 years can be listed.

Because the government can replace fossil fuels for low carbon energy subsidies to support and expensive to install solar power systems will soon become a global trend.

However, its share of global electricity rate of 1% -2% of view, the basis of such growth is still very low. Currently, most solar panels formed by the ultra-pure silicon. Plastic alternatives appeal lies in the use of printing and coating technology, the battery plate production faster and cheaper.

A group from Sheffield and Cambridge as well as some other organizations, researchers said, and now they are manufacturing such products has become more proficient. While other research groups in the efficiency of plastic solar battery for further study.

 ”I think in the next five to 10 years, you will see such a large-scale installation of the system the product.” Richard Jones said the University of Sheffield. In addition, he also said that the development of plastic solar battery panels are still some obstacles, such as how to extend their service life.

June 22, in recent years, the media, the lithium-ion battery cathode material - lithium iron phosphate is very confusing reports of patent disputes.

Currently in China, lithium-ion battery is a local company involved in the choice for battery electric vehicles. And also widely used lead-acid batteries and nickel-metal hydride batteries, lithium-ion battery energy storage better, greater energy density, longer cycle life, no memory effect recharge better, and can basically meet the size, life span, Power and other electric vehicles require a higher demand.

Reporters learned that the lithium-ion battery performance depends on two factors: First, the quality of lithium iron phosphate; second lithium-ion battery production equipment.

Lithium-ion battery production process is extremely complex, the necessary equipment and testing instruments of more than 100 species. From the point of view this exhibition, in addition to individual testing instruments, domestic enterprises can meet the basic needs of all the equipment, but the import of key equipment is reliable. Production processes such as batteries, anode and cathode materials must be uniform coating is critical to ensure consistency of single cell processes, it is mainly the domestic equipment; imported membrane coating nanoscale thickness of only 30-40 microns, domestic equipment simply can not do; in the battery electrolyte into the single links, workshop environment requires not only a constant humidity and temperature, but also require clean, mixed with an electrolyte in the dust, it may cause the battery to short circuit.

Currently on a global scale, the initial commercialization of electric vehicles and plug-in hybrid expensive, mainly because the manufacturing cost of lithium-ion batteries get down, the biggest one is the investment in equipment. It is understood, Shenzhen, BYD is the construction of a new lithium-ion battery production base, all equipment imported from Japan, a total investment of more than 50 billion, the purpose is to maintain its electric vehicles in the domestic market leader. The problem is, the next 10 years, the commercialization of electric vehicles will not be a major breakthrough, when such a large investment costs can be recovered?

Microsoft recently released the report entitled “win7 Power Management” 14-page white paper describes Windows 7 Power Management technology is how to reduce energy consumption. If you want to know exactly how energy efficient, the white paper will give you the answer. If you just want quick and easy to understand, the following will tell you that Windows 7 primary means of energy conservation.

1,idle resources power consumption

When a computer starts, not always running at full capacity, so there will be a lot of free time, so the idle time power consumption becomes an important power management technology. In win7, the idle power consumption has been effectively improved, when a hardware is not working after a certain period of time will enter a low power state has to save battery power. Including CPU, hard disk, memory and network elements have adopted this technology. For example, a full-power operation of the CPU power consumption 35w power consumption at idle is almost 0, only this one will be able to save a lot of power.

2,by the trigger to start the service

Usually the system will be in service when the system starts with the start, and then resides in the background waiting for calls. In Windows 7, the service is only part of the system is triggered by some event until after the start, such as the insertion of a device or change the IP. This reduces the long-running background process in the number of services.

3,increased processor power management

win7 integrates the latest in power management technology, which allows Windows 7 based on the current load and performance requirements to dynamically adjust the CPU performance.

4,Adaptive display brightness adjustment

Microsoft said, usually 10-15 minutes in non-operation, the monitor will automatically shut down. However, in actual use will be more short-term non-operating conditions, in order to better energy efficiency, the technology will reduce the display brightness. In addition, it can take advantage of some of the sensing device, according to the ambient light to adjust the display brightness.

5,low-power audio

win7 will support Intel’s low-power HD audio specification, it allows the codec to enter the low power battery state. win7 also supports selective suspend technology to shut down idle equipment, such as microphones and cameras such USB devices.

6,timer integrated

The current processor instruction space through the use of spare processing time to save batttery energy, but most of the energy-saving technologies need a certain length of idle time to get energy-saving effect. And this technology by making the Windows kernel to terminate at the same time and focus more dispersed than the original timer, disposed of in a short time, thus increasing the processor’s idle time.

In addition, when using the battery in the laptop case, win7 will reduce non-critical activities daemon frequency.

7,Bluetooth devices to improve power

When win7 detected Bluetooth devices in a low-power state, they will be temporarily closed, the “selective suspend.”

8,network equipment to improve power

win7 in the radio network controller for low-power mode compatibility has been enhanced, and only in the wireless AP devices support low-power mode in the case will be enabled. Vista because it can not detect in advance whether to support low-power mode, the wireless network connection will lead to a sudden interruption. win7 will prevent this from happening, before entering the low power mode will detect the first wireless AP support this mode.

9,Typical application optimization

In addition to the above listed improvements, Microsoft also turned to some specific applications, including search, browsing and small game without networking. Here is the DVD player where the optimization part:

Without affecting the playback performance under the premise of the CPU to maintain low-power mode

By changing the structure to improve the desktop window manager and GPU power

Intelligent data caching can reduce the drive speed

The above is in power management win7 nine important improvements compared to the previous system can save more energy. In addition to these improvements, IT professionals can use to find the power management may affect the diagnostic efficiency of the power supply problem.

According to foreign media reports, Samsung 10-inch Tablet PC Galaxy Tab 10.1 which will for sale in USis thinner than iPad 2 but the battery life is much worse.

According to reports this week and found the actual use, and finally have a tablet PC than iPad 2 is really thin, even if only a thin 0.2 mm; and Galaxy Tab 10.1 iPad 2 lighter than the former and the latter weight 1.25 pounds 1.33 pounds.

Boehret trial in the United States is on sale this Friday, only Wi-Fi connectivity of the Galaxy Tab 10.1, Capacity 16 GB version for $ 499 each, 32 GB version priced at $ 599, then the same with the iPad 2.

However, with the fourth generation communication system (4G) connectivity of the Galaxy Tab 10.1 will also be on sale next month, with the largest U.S. mobile provider Verizon network, 16 GB and 32 GB version priced at $ 529 each and $ 629, less than Verizon and sold by iPad 2 price, the same version for the price of $ 629 and $ 729.

However Boehret that these two Tablet PC’s biggest difference is that battery life. According to her 75% screen brightness with continuous video playback test, the Samsung Galaxy Tab 10.1 Battery only for 5 hours and 38 minutes, compared with iPad 2 hours, 9 minutes, 10 more than half a little bit.

On the other hand, Galaxy Tab 10.1 to adopt wide-screen size, more than 9.7-inch screen iPad 2 slightly longer; and its two-way cameras captured the picture quality, good than iPad 2. However, iPad 2 iOS operating system used by the applicable number of applications, than the Galaxy Tab 10.1 using the Google Android operating system, hundreds of thousands more .

Laptop computer can make more than ten hours of fuel cell has attracted the attention of computer experts, but first to prove this is safe, such as duty-free vodka along with the flight time. Japan is currently leading in a small fuel cell technology.

Production of fuel cell components Goodman, president of Entegris, said that although alcohol is flammable, but methanol fuel cells in the water content of less than 24%. He said: “The problem is not a flammable liquid on the plane is safe, it has been in alcohol and perfume have permission.”

Toshiba, NEC have developed a prototype laptop fuel cell, plans to become a comprehensive range of products next year. Casio, Sony, Hitachi and Samsung is also studying the micro fuel cell technology. Goodman predicted will occur within a few years does not exceed the size of a lighter fuel cell, can be used more than ten hours. He said: “After ten hours spent to put the old battery into the size of an inkjet printer cartridge and put another battery charger.”

In February, Intel announced that the companies they invest PolyFuel produced a fuel cell can be used in notebook computers. The traditional life of laptop batteries three to four hours, the fuel cell goal is six to eight hours, and ultimately to reach 12 hours. The price of fuel cells is expected to start at $ 200, the traditional battery for $ 120 to 180 dollars. Expected to fuel cells will initially be prepared as a general battery supplies.

Experts believe that laptops will become the first fuel cell technology mass market for mobile phones and compressed to the size of the research will take a long time, cars and gas stations will need to address infrastructure problems. SRI analyst at West Don, said: “notebook computer manufacturers want to add some high energy consumption without reducing the function of battery life.”

In recent years, has been a very hot smartphone the key. Now has entered the era of smartphone popularization. And this among them phones that the forensic system in the development of a blowout type strong legion. Of course domestic manufacturers also seized this opportunity. From the beginning of the huawei, zte, mobile phone $1,000 ophone system customizing machine, to now basically giant in this year will out their own android smartphones.

Cool is a shining example. The titanium alloy enclosure from jing N930, to W711 and thousands more intelligence D530. But as in the aspects of some deficiencies. And today came to south China D539 perhaps is the assessment room fill this imperfections.

Cool D539 is in a dual mode double for the smartphone in forensic. Support telecom 3G and China mobile, China unicom’s GSM network. And in its hardware configuration is using the ARM cortexA8 architecture of high-performance CPU - Texas instruments than 600M OMAP3430, presenting the same frequency, the CPU strong ARM 11 twice. Its PowerVR SGX the GPU is 530, memory RAM for 256M, whole hardware with MOTOROLA milestone is same, can smooth play want to “angry birds,” “ninja watermelon” mainstream games, is very sharp.

Another noteworthy is cool D539 has a large capacity battery 25 ma, solve most of the smartphone battery standby time is short for, this is by far the biggest battery capacity of forensic smartphone.

Cool D539 using Android 2.1 version of the operating system, and the other models have cool 2.2, believe D539 upgrade 2.2 is not far away. On modelling DaBing touch by straight for the 3.5-inch screen, the resistance of the screen, resolution for the 320×480 HVGA level. On the cortexA8CPU 600M, match again, let D539 prior to the series in.

In appearance, D539 N930 fan is cool, edges and trenchant. Very And in the size, the fuselage of 120 x 62 x 15.3 mm, ha ha, thicker. This is to buy large capacity of the battery and sacrifices, of course, to range it is worthwhile. In comparison, also feel than general mobile content, more heavy. More in line with the needs of close to men.

D539 back in cool, the comparison of the overall use composed short and concise, tonal, the black brown for grinding materials, feel good. Overall, only have below a cool LOGO, for a 300 million above the camera and a linear speakers, and whole set is one integrated mass. On the positive, cool preserve only three of the forensic system must use buttons, tell the people with less search button.
