Lower this year, greatly increased the demand for photovoltaic cells, is worth polysilicon call an important reason. In this regard, this site was informed that polysilicon rally round 50 dollars from the end of last year / kg bottoming out, but domestic production is still excess demand for short-term stimulus is not a continuation of polysilicon is expected to continue rising up to six months, or up to 30% will not be much impact on the industry. The long term, polysilicon thin film and other new materials or alternative path nikon EN-EL4 charger nikon EN-EL4a charger .

Or put a temporary rebound in long-term

Industry sources say that the domestic spot price of polysilicon has more than 70 U.S. dollars. Domestic polysilicon manufacturer, a large media executives confirmed that “as far as I know, no surprise rise above 70 dollars. In the end of this year, polysilicon spot prices rise above 100 U.S. dollars will not be much problem.” The executive said, ” downstream of this year (ie, crystalline silicon PV cells and battery components business) greatly increased demand, the original view that the European market as Germany and Spain reducing subsidies occur demand declined significantly in the case, it now appears we were overreacting. in fact Europe market demand is still growing, but growth rate down. ”

Director of Energy Technology Co., Ltd. Guangzhou Yasuharu He Ping accepted an interview with the South have said the current round of rising polysilicon prices are actually relatively rebound before the battered, but is not expected to go up a long, sustained rally up to six months, or up to 20% to 30%.

He Ping analysis, in May 2008, polysilicon spot price shot up to 500 U.S. dollars per kg, but then dropped, the end of 2009, polysilicon spot price fell to around 50 dollars. Recent polysilicon up to 70 U.S. dollars / kg, from the bottom up, but once again rise to the possibility of a few hundred dollars a kilogram of almost zero. Domestic production of polysilicon large listed companies such as Suntech, performance is not good, industry competition is still fierce.

“Short-term rise, long-term are not optimistic.” Xiamen University, China Energy Economic Research Center director Lin Boqiang told reporters Southern, the current round of inflation is restorative, mainly stimulated by the short-term factors, one European government will abolish subsidies for solar industry, related companies rush to buy time for the subsidy is abolished, leading to rising demand; Second, China’s second batch of 280 MW PV power station tender, have stimulated demand. But in the long term, the current production capacity of polysilicon in China remains a serious surplus, which is why the state will limit the production of polysilicon. Even so, no new projects are put into the original project is excess capacity, “so-called capacity planning to say, is wrong.”

Polysilicon or phased out

Crystalline silicon cells and the downstream crystalline silicon battery components manufacturers, the crystalline silicon raw material price increases, its performance and gross margin will be adversely affected. Zhejiang Chint Solar Energy Technology Co., Ltd. Strategic Marketing Manager Hu Wan-book an interview that the company is bearing the upstream silicon raw material price increases cost pressures. If the polysilicon continued to rise, then the first half of next year, the industry may go into difficulties, but this time not very long NB-2L NB-2LH .

However, an interview about the situation, most of polysilicon is expected to continue to rally round the end, will not last until next year. Xiamen University, China Energy Economic Research Center director Lin Boqiang that even the year after next year, polysilicon will not rise, the state will continue to limit the capacity of the industry.

Moreover, new technologies, new materials is likely to replace silicon. Director of Energy Technology Co., Ltd. Guangzhou Yasuharu He Ping told reporters Southern, polysilicon is still high pollution and high energy consumption products, conversion rate, and consumption of resources is bound to be phased out. Now there’s silicon-based films, many with high conversion rate will be the future. Xiamen University, China Energy Economic Research Center director Lin Boqiang also said the new energy sector development of new technologies very quickly, once the new technological breakthrough, polycrystalline silicon will not be mainstream.

Actually, some companies have begun restructuring the industry, not to its polysilicon production or as raw materials. Involved in solar energy, the new Austrian Southern Group spokesman told reporters that the company will use solar power silicon thin film components, instead of polysilicon.

Controversy or lack of excess production capacity of polysilicon?

Polysilicon price gains this round, the industry, there are two voices, one that the domestic capacity planning, price will rise; The other is that excess capacity, gains not sustainable. Whether the excess production capacity of polysilicon, the key is to judge, but arguments have not yet taken.

September 2009, the central authorities issued a notice, finds that polysilicon production capacity surplus. Xiamen University, China Energy Centre for Economic Research and the Ministry of Education, Science and Technology Commission Director Lin Boqiang Ni Weidou have accepted an interview with the South believed that the industry overcapacity, low-level redundant construction to excess most of the companies relied on all eating of government subsidies, the actual efficiency is poor NB-4L NB-5L .

However, domestic high-quality polysilicon still rely heavily on import. The industry believes that “excess capacity on the” take the letter are planning capacity, and far from actual output. The construction of the project with the polysilicon production technology cycle longer relevant, on the other hand, due process and technical reasons, planning capacity may not be able to form the actual output.

NDRC Energy Research Institute, Li Junfeng, deputy director of media interviews that the Government of the polysilicon industry overcapacity determine the actual control of the new energy industry is the low level duplicated construction emerged, on the high level of productivity is still supportive. The domestic production of polysilicon, the biggest problem is the key technology and equipment is still not fully grasp.

Most of the answer is calibrated once a month. For the memory effect of a strong Ni-MH battery, this is right, but for lithium batteries, the cycle would be too frequent, lithium batteries, although not completely eliminate memory effect, but has greatly reduced the memory effect, if you use the battery is frequently, then you should discharge the battery to the lower (about 10-15%), recharge, but even if the discharge to the machines they can not (0-1%), it is damage to the lithium battery has a greater depth of discharge generally done once every 2 months, so the operation on it. If you rarely use your Samsung battery  Samsung X10, as long as once every 3 months this operation on it .

July 25, in line with “Jawaharlal Nehru National Solar Programme,” The implementation of the new Indian Energy and Renewable Energy Department issued a “right and power generation of advanced solar projects policy guidelines.” Tutorial contains the “Buy Indian” provisions.

The guide is the fifth part of the second chapter, “solar photovoltaic project selection criteria” in Article 4 of “local self-made” emphasizes: India’s “national solar plan” an important goal is to promote the development of domestic manufacturing, project developers as far as possible use of their manufacturing facilities in India.

However, the first elected into the 2010-2011 fiscal year the government plans to support solar projects, the guide asked, crystalline silicon technology projects and opening up business “must use its own manufacturing solar modules in India.” For the second fiscal year 2011-2012 to support the project, the guide said that these projects will use India’s domestic manufacturers of solar cells and modules laptop battery Acer battery .

Although the guide did not say ban the import of solar cells specific execution time, but New Energy Investment Company Norasco head Ajay Goyal told reporters: From next March, these selected items have to use Indian-made solar cells.

Government of India launched at the end of last year, “Jawaharlal Nehru National Solar Programme”, hoping through the implementation of the plan to enhance India’s domestic solar power generation and industrial strength, and then to India to become global leaders in solar energy industry. This program includes both photovoltaic and solar thermal energy most, three-stage plan in the photovoltaic market in India by 2013 the cumulative total can reach 1GW, 2022 to 20GW, and solar thermal energy in part to 14GW.

July 25, India’s new energy and renewable energy minister, Farooq Abdullah, speaking in New Delhi made it clear that “India is the government’s top priority.”

“In the national solar program first stage of implementation, you can use imported equipment, but this does not mean that you do not use Indian companies Zhizao solar equipment. But in the second phase, you will be allowed to import foreign product.” Farooq Abdullah said in his speech.

The resolution has been Tata BP Solar India’s Moser Baer solar energy company and the company’s support and welcome. The two companies are the largest solar photovoltaic industry in India manufacturers.

Once the implementation of this policy will harm China’s export of solar energy companies in India. In the interview, Ajay Goyal told reporters, “now is a golden opportunity to invest in solar projects in India, the Chinese solar energy companies can also consider manufacturing in India.” Apple battery Asus battery

New World Solar Energy Industry In recent years the rapid development of crystalline silicon photovoltaic cells are still in mainstream, occupying 78% market share. According to industry forecasts, over the next 10 to 15 years within the crystalline silicon photovoltaic cells will continue to occupy dominant market position. Theoretical limit of crystalline silicon cell efficiency of 31% (called Shockley-Queisser limit, SQ limit), how to break the SQ limit, greatly improve the utilization of sunlight, is the world’s photovoltaic research and industry is very concerned about hot research.

Institute of Microelectronics, Chinese Academy of Sciences Laboratory of microwave devices and integrated circuits (four rooms) Jia Rui researchers led by high-performance solar cell research team led by the strong support and leadership of the office, the first in China on semiconductor nano-materials under the conversion efficiency of crystalline silicon solar cells, nano-materials through the use of semiconductor quantum confinement effect size width can be adjusted to increase the response to short wavelength light band HP Pavilion DV2000 Screen HP Pavilion DV3 Screen .

The discussion group has successfully developed a new type of semiconductor nanomaterials, the new width of the semiconductor material can be according to size, materials, components, etc. and flexible adjustment. The next conversion materials and mass production-type 125mm × 125mm crystal silicon substrates was developed for the next conversion efficiency crystalline silicon cells. Cells are encapsulated in the corresponding post-tests show that the down-conversion crystal silicon cells increased significantly in the 300-630nm band of light absorption and utilization of spectral response rate of increase by 10%, significantly improved the crystalline silicon cells performance.

Jia Rui researchers have been invited to convene in August 2010 the Second International Photovoltaic Forum on China-EU made a special report, elaborated and presented the research results have been Chinese and foreign experts and industry recognition and praise, for the Institute of Microelectronics research in the area where the solar cells laid a good foundation HP Pavilion DV6 Screen .

Tokyo Institute of Information Technology analyst Hideo Takeshita said the lithium-ion batteries this year’s price increase will reach 19%, the highest in nearly five years. Japan’s Nomura Holdings Inc. analyst Shiro Mikoshiba more pessimistic view, the growing excess capacity rechargeable battery will allow up to 25% lower prices.

In the occupied 75% of global production capacity in Japan and South Korea, this phenomenon is more prominent. With the development of electric vehicles, lithium ion batteries will be sold the next six years to three times the current, so the battery manufacturers at the expense of profits to gain more market share Lenovo ThinkPad X300 screen .

Ichiyoshi Investment Management general manager Mitsushige Akino said that as prices fall, the battery manufacturer may be going through a difficult period. Only the market share from larger vendors will profit, others difficult to share a Fengeng.

Analysts Takeshita said, compared to competitors in Japan, Korea, life is very better than the manufacturer. Because they can buy cheaper from China of raw materials, production and more rapid, and the end of the won-yen exchange rate makes South Korean manufacturers more competitive.

Matsushita spokesman said: “We and the South Korean manufacturer price war will continue, we will re-examine the production process to enhance cost competitiveness and win the price war.”

Tokyo Institute of Information Technology is expected that Samsung SDI is likely to exceed this year, Sanyo (Matsushita has been fully acquired) to become the largest manufacturer of lithium-ion battery Lenovo ThinkPad T400 screen Lenovo ThinkPad X200 screen .

Currently solar energy market in general, less than 1% share, but Frost & Sullivan predicted that around 2050, with the oil, gas and other traditional energy supplies become tighter, the overall solar energy market will achieve significant market share growth. 2008 global PV industry chemicals, the size of the market 3.06 million. Frost & Sullivan estimated that by 2015 the market will increase to 2.808 billion U.S. dollars.

According to the China Association of epoxy resin industry experts, the exposure to the silicon materials into the sun and store them for current production and living use, this is the use of photovoltaic solar energy photovoltaic effect to convert. In 1950, the photovoltaic effect was first used to supply power for space satellites. As an inexhaustible source of energy, solar energy is being developed into new energy sources to replace traditional green alternatives, and the solution to future energy crises of the response options dell Studio 1535 Screen dell Studio 1536 Screen .

In fact, the potential energy from the sun each year is equivalent to 44 megawatts of electricity, enough to meet current global energy consumption for four years. At present, solar energy is widely used in aerospace, off-grid areas, public facilities, commercial facilities and residential houses. Reduce dependence on traditional energy sources, resistance to climate change and energy independence is maintained by three major driving forces of renewable energy.

Solar energy is widely used in aerospace, off-grid areas, public facilities, commercial facilities and residential houses. End users of solar energy on solar energy have different requirements. For example, users of public facilities, because they have a lot of land, so the solar cell performance is not the most important component. For residential and commercial users, the limited land to make them more popular and efficient solar power generation facilities. There is also equipment suppliers began to provide solar energy in remote areas of the facilities to meet their pumping, road signal signs, parking timer, and even the power supply demand for personal electronic devices. The market has just started, in the long run is the market potential.

Chemicals in the application of photovoltaic industry more photovoltaic industry chemicals market is still in growth stage. Currently, worldwide more than 40 domestic and foreign companies active in the PV-related chemicals market. European companies dominate the market, but Japan and China PV industry in recent years, the company’s market share is increasing. Large companies are Dow Chemical, Linde, Mitsubishi, and Ashland and so on. The large multinational companies have localized sales, technical support and customer service team. PV-related chemicals, mainly through direct sales or distributors to carry out, the main end-customers are manufacturers of polysilicon and wafers, monocrystalline silicon and solar cell manufacturers and solar module manufacturers. In addition, the manufacture of PV modules also need to use various types of daily and special chemicals dell Studio 1537 Screen dell Studio 17 Screen .

At present, because the high cost of solar energy applications, the price is generally not competitive, the development of PV industry encountered many obstacles. However, because the amount of solar radiation in different countries, different national conditions and economic level have led to the PV industry in different stages of development, while the solar feed-in tariffs, there are big differences.

In 2008, total installed generation capacity of solar energy is 13.5 billion kilowatts. Among them, the newly installed generating capacity of 5.5 billion kilowatts. Germany, Spain, France and the United States market in 2008, to a certain growth. At the same time, China market has become the largest market for solar modules to install one. India and other fast-growing Southeast Asian countries are also greater use of solar energy. Although in the global value of the German sun and not the highest, but it is the largest regional market photovoltaic industry. The German government issued a series of policies to promote the development of photovoltaic industry, such as the end of 1990 declared the “1000 Plan photovoltaic roof,” that is ready in 3 years, residents of the roof installed in 1000 sets of 1 to 5 kW of photovoltaic power stage power system for grid-connected PV systems investigated the economics, technical feasibility and practicality. Italy may be the first in Europe to achieve a breakthrough solar energy costs and prices of countries, the price of solar will achieve grid parity by 2010. France is stepping up construction of a series of photovoltaic installations. Spain in 2008 to install a number of large-scale deployment of photovoltaic equipment. Spanish government in September 2008 to encourage large-scale ground before installation, from 2009, required annual amount of solar energy equipment installed on half of the roof to be installed. This policy in 2009 limited the development of the market. In the sunny Aegean coast of Greece set ambitious goals, to be completed in 2020, has 700 million watts of solar generating capacity. Greece in 2008 solar power generating capacity of 18.5 megawatts assembly machine.

In South America and North America, Canada has initiated action to green energy and green economy. Currently existing in Canada less than 50 megawatts of solar generating capacity. Canada may be in this area has enormous growth potential. At the same time the U.S. government has passed a series of preferential policies to promote the development of photovoltaic industry. Similarly, in Asia’s rapid growth in Japan is the world’s largest solar cell manufacturers. However, as the Japanese government in 2005 to stop the housing subsidy program, the PV market, the actual state of stagnation dell Studio 1720 Screen dell Studio 1735 Screen .

Expected next year, the Japanese government in order to achieve its set of solar power by 2020 cumulative goal of 1,400 megawatts, will be resumed domestic subsidies, which continue to promote PV market. According to the China Association of epoxy resin industry experts, although China PV cells and modules in the areas involved in mass production, but 95% of the products for export. However, as China’s growing energy demand and the general lack of power situation in rural areas, China’s solar market is expected to have broad prospects. Recently, the Chinese government put forward to the PV industry subsidies, despite the current subsidies are capped at 20 megawatts or less, but the subsidies each year by the Government to assess the continued growth in the future possibilities. The news no doubt to the Chinese domestic market for PV industry hit a shot in the arm.

In the recently held 240th Session of the American Chemical Society national meeting, researchers described the solar cell, which not only achieve self-cleaning, but also improve the efficiency of solar energy power generation, reduce the maintenance cost of large-scale solar equipment.

This self-cleaning technology mainly deposited on glass or transparent plastic layer of transparent thin layer of electric-sensitive materials to cover the battery panel. From the sensor to monitor the dust level of the battery plate surface, when the dust density reaches a certain level will be energized, the charge will be able to send a dust exclusion surface wave, the dust pushed to protect the screen edge. Mazhamuda that this technique in 2 minutes, remove the battery panel can be about 90% of the dust, the entire process consumes only a very small solar panels generate their own amount of energy dell Inspiron 9200 Screen dell Inspiron 9300 Screen .

Leading the research Mahler.Mazha Mu attained Ph.D. Boston University, said just 4.05 grams per square meter of dust layer can be reduced 40% solar energy conversion. This self-cleaning solar panels do not even need the help of water or mechanical, is ideal for dust and particulate pollution in the highly concentrated regions.

In the United States National Aeronautics and Space Administration work, Mazhamuda and his team have developed a task for the moon and Mars solar panels automatically clean technology. “There is no doubt that Mars is a dusty and dry environment, solar panels have to roam the astronauts in space to provide energy, and ensure the future mission of the controlled robot will not be troubled by the dust.”

With the popularity of solar energy, this technology will increase the use of space. From 2003 to 2008, solar, or photovoltaic panels use increased by 50%, is forecast to increase for at least 25% every year. Current market share of solar panels is about 24 billion U.S. dollars, the global power of less than 0.04% from solar cells, and if only 4% of the world’s deserts to produce solar power, can satisfy the world’s energy needs dell Inspiron 9400 Screen dell Inspiron E1405 Screen .

There is also a snow countermeasures can be used as an effective way. This is the single-axis tracking solar cell systems. This is an action with the solar cells, solar cells change from east to west point of the system module. Originally aimed at optimizing the use of angle of incidence of sunlight and increase output power. Wakkanai city facilities are also used for snow removal of the system. For example, at night to increase the angle of solar cells, it is difficult snow conditions, snow fell early in the morning to join to promote action. However, the issue is single-axis tracking system, the cost of shelf units, compared with the general framework sets per kW to 1.5 to 2 times higher dell Inspiron 1300 Screen dell Inspiron 1420 Screen .

Taiwan’s cost-cutting on the shelf, juvenile facilities within the general framework is promoting Taiwan to cut the Department of the experimental material. Like with Hokuto City, the Department of material usage reduction is the key. In addition, measures must be considered in the frame to be used as snow Height, and snow when the frame units durability. Weather conditions through unique Hokuto City, and snow and other severe weather conditions, Wakkanai City, empirical confirmation of two cities, “can be anywhere in Japan, building megawatt-class solar energy power stations.” dell Inspiron 15 Screen

So I said to him, choose this “endurance” of the notebook to note the following:

 1. Battery capacity the bigger the better. Six core (50Wh or so) is the most basic, eight-core (80Wh or so) is desirable, if the hardware is not power, it is best they are worthy of a spare battery.

 2. Processor power consumption as low as possible. I now mainstream Core series processors are mostly 35 watts, while the i5-520UM such as ultra-low voltage processor is only 18 watts, but also built-in graphics chip.

 3. Must have integrated graphics. There is no doubt set were significantly more power than independence, and now a new generation of notebook was both a unique and significant collection, and even automatically switch, which undoubtedly is a best of both worlds solution.

ASUS’s product line in, U series on the main portability and Asus battery life time, which focused on the ultimate light UX, and UL are in stress endurance performance, while also not neglected. Now, paragraph UL80Jt 2010 ushered in a more intelligent Core i5 processor, it both in performance and endurance performance then?

Measured: body thickness, with the weight of eight-cell battery

Divided by the screen size, there are three Asus UL Series, they are 12-inch UL20, 13-inch and 14 inch UL30 UL80 (estimated to be shy about 4 this figure, there is no named UL40). Which, UL80 although not as good as the first two in terms of portability, but it is the only built-in optical drive models, and better heat dissipation point, the screen looks bigger and more comfortable.

Test results from the above perspective, UL80Jt not really the ultimate light, but the 14-inch models and ordinary compared to edge down slightly, as we have said before, its biggest selling point is not portable, but battery life , standard 8-cell battery of the notebook can be rare, larger battery will inevitably increase to some extent, the weight machine.

 Display and appreciation of the fuselage details

To protect the delicate of the LED backlit screen, want to maintain the books of the slender metal roof material would be ideal. I am in the process of writing, when the palms sweat when typing playing, go touch UL80Jt the roof, look at the cool of the. Although it’s palm rest is plastic, but no way in the evaluation process heat, cooling ASUS notebook has been very good, you can heat conduction to the right outlet, but will not come from the palm rest surface, revealed.

 Multi-touch panel, the fuselage on the left interface,

Here to talk about operating handle it. UL80Jt using chocolate keyboard keys from misuse more difficult, very good flexibility, is the Caps a bit slippery surface, key-way or partial short, the general feeling quite satisfactory, so long as not a long period of continuous typing is no problem. UL80Jt of the touchpad surface fine particles, operate very comfortable, not feel slippery or jerky. But there seems little question: If the screen is 16:9, the touch pad is 16:10 then why? On the other hand, are more hard about the kind of button, press the next bit of energy is required, as to whether the user likes to vary the  Asus ac adapter  .

UL80Jt a total of three USB interface, the left two, right one, in general it is basic enough, but the two USB interfaces on the left is not too far away, when the USB device size is large, the interface may cause side can not be used. In addition, we also noted that the design of old and new in appearance of two UL80 little difference, it seems only the internal processor, video card and some software upgrade only.

Life time of the initial test, next notice

We will power management set to power saving mode, the battery simulation test, we have seen in the standby mode (low load), the ASUS UL80Jt the expected life time of 10 hours. But when we loop a 720p HD video (high load), estimated life time was 5 hours 19 minutes. Of course, this prediction is not very accurate, we need a few real battery .
