Improve the conversion efficiency and lifetime of solar cells and modules R & D focus

Despite the financial turmoil sweeping the world severely affected, making a number of solar photovoltaic production enterprises have to take shrinkage and cut approach to overcome the temporary difficulties, but the solar PV industry will certainly survive this crisis is the industry’s fastest . It was predicted that the second quarter of 2009 will see the industry’s full recovery.

China’s production of solar cells and modules and applications began in the early 70 century, but behind its production, manufacturing costs are high, coupled with higher conversion efficiency reasons, in addition to apply some special environment it was hard to promote to the civilian area. Since entering the 21st century, a number of studies students returned, bringing back foreign advanced technology and management, have created a more professional in the country, but also relatively large scale of the company, making China the production of solar cells and modules, whether the quality of on the number or both to a new level. Which was founded in 2001, after years and Suzhou Artus Suntech is very typical. Particularly successful in 2005, Suntech listed on NYSE in the U.S., and more than 400,000,000 U.S. dollars a financing can be said that solar photovoltaic industry in China is a breaking news. Then have another dozen solar companies listed overseas, the financial return billions of dollars of funds is huge, which greatly expand the strength of China’s PV industry.

I think the beginning of this century, China’s solar cells and modules to the sustainable development of high-speed four main reasons: First, the global fossil energy prices and the continuing rapid deterioration of the Earth’s environment to accelerate, driven by governments and peoples of renewable energy eagerly look forward to; two solar photovoltaic technology itself is the tremendous progress made in the laboratory to achieve the original conversion efficiency, is now in mass production can be achieved; Third, financial and stock investors have on the solar PV industry enough confidence to make photovoltaic industry have sufficient financial support; Fourth, the reform and opening up, China has become the world’s investment in processing industry park, leading many returnees to return to the smooth development of entrepreneurship.

In recent years, China’s solar photovoltaic industry to make the world wonder of the double speed rapid development, in 2006, China’s solar cell output was only 380 MW in 2007 to more than 1,000 megawatts, accounting for the global 1 / 4 also , and this is almost the global output in 2004 rather, and will thus become the world’s largest solar cell producer. This makes the solar energy industry in China is not only a world first solar thermal products, and optoelectronic products also ranks first in the world. We should be proud of and proud. I said, the solar energy industry is a glorious and light industries, it glorious, because it not only provide energy for mankind, but also provide much environmental value of clean energy; it light, this business is the development of some extremely good future, perhaps in another 23 years, it is the main human sources of energy.

At present, even though we face the global financial turmoil sweeping the serious impact which some solar manufacturers have to take shrinkage and cut approach to overcome the temporary difficulties, I have always believed that solar PV industry will certainly be the fastest the industry through this crisis. It was predicted that the second quarter of 2009 will see the industry’s full recovery. Because so far, national economic recovery plan announced by the Government regard the saving and environmental protection on a very important position, the solar energy industry in the spring will soon come, I believe that.

The development of China’s solar PV industry is at a critical time, we still have a lot to do.

First of all, we are faced with the problem the grave shortage of high-end, almost all of the PV companies lack a strong R & D team, in the PV industry chain and all links in a large number of technical difficulties, need to tackle key problems, such as how to make silicon do more thin, more economical high-purity silicon material; how to make the battery more than 20% conversion efficiency; how to further improve the service life of components and so on. These things only by a company is difficult to do because it takes a lot of money and a lot of manpower, more important is the need for a leader in high-end talent. So I suggest that the domestic relevant departments come forward to organize robust domestic solar PV Technology Research Institute jointly established companies, which can not only carry out solar energy development and utilization of high-tech research, but also training a number of high-tech talent, that on the sustainable development of China’s solar energy industry will be crucial.

Second, in all aspects of PV industry chain, such as high-purity polysilicon, wafers, cells, components of the key production equipment also need to import, the localization of these devices is not high level, also need to put in the necessary financial and human must be developed.

Finally, China’s PV market with our photovoltaic manufacturing world is very disproportionate compared to 2007, China produced more than 1,000 megawatts of photovoltaic products, 99% are sold abroad, our own use less than 1%. Therefore, our application of PV products in the promotion of the Government and the public need to redouble our efforts.

In recent years, we are pleased to see that many of our leading solar photovoltaic companies have put forward a clear goal: Suntech made, three to five years, so that the cost of solar power to 1 yuan / kwh; Suzhou Art Williams said that in the next three decades, so that solar energy into millions of households; LDK asked to be world’s largest solar wafers, to best quality, lowest cost. If these objectives can be achieved, we will truly become the world on a world full of sunshine.

ABC Listing: disposal by sale or disposal by sale to the war vote to the market?

Workers, in construction of three state-owned commercial banks in the A share market was over 24 times earnings, the present, the dynamic price-earnings ratio is lower than the Bank of China 10 times, ICBC, CCB less than 9 times, including China Construction Bank has long leaned firmly below the issue price. Under current conditions, the Agricultural Bank To IPO is clearly difficult to achieve. In addition, the other three were brought before the Bank IPO overseas well-known financial institutions as strategic investors, it is undeniable that these investments make money overseas war, and the participation of these institutions, but also to ensure the success of the three firms into Hong Kong issue, played a “hidden security” role. ABC is not bringing in overseas war vote could mean the loss of the implicit guarantee, combined with recent audit department released its audit report illegal operations and the media crush, so that it casts a shadow over the market.

Agricultural Bank of China IPO point in time there are only two possible choices: To the recent listing of major shareholders ABC Huijin another major shareholder of the Ministry of Finance may even boost the flagging stock market shot at least maintain the stability of bank shares. Otherwise, they can delay IPO, better wait for the market to say, or distribution in danger of collapse, at least not a better price. One insider told the “China Times” reporter, compared to the first possibility of larger, in addition, ABC This may be issued at 20 times earnings.
Agricultural Bank of China IPO, if not ideal, it can not for the state-owned commercial banks, ending the war and draw a full stop.
Exchange gold for the other three lines injected to ensure a successful ABC IPO

Whether overweight BOC, ICBC and China Construction Bank shares, or reduce the proportion of dividends from the three lines, the purpose of Huijin only one: that is stable capital markets, banking stocks helped to ensure the success of the Agricultural Bank IPO.

Late last month, SAFE Investments Limited announced on support of the ICBC, BOC, CCB 3 about to cash dividends in 2009 increased from 50% to 45%, to improve the three lines through internal accumulation of capital, the ability to add and actively support and participate in various lines of re-financing plan.
In 2009, ICBC, BOC, CCB and other large state-owned commercial banks to increase the credit strength, the massive growth in business volume, while the capital adequacy ratio decreased rapidly.

Raise bank capital adequacy ratio, there are four ways: First, re-financing in the secondary market; second is to reduce the dividend ratio, dividends would translate into a part of the capital; 3 is to reduce the loan; Fourth issue subordinated debt, but it can only enhance the capital adequacy ratio, can not raise the core capital adequacy ratio. A third approach difficult to implement.

As the SAFE notice said: “My company believes that large commercial banks ordered additional capital, the maintenance of capital market stability, and promote the healthy development of large commercial banks are of great significance.”

As early as October 9, 2009 stock index fell 2,800 points, Huijin once ordered to support the market first, stability maintenance, announced ICBC, CCB and Bank of China started a period of one year to stabilize the stock holdings, This initiative led to the Shanghai index jumped 131 points, or up 4.76%, Industrial and Commercial Bank of China closed at 4.77 yuan after, to close at 5.58 yuan after China Construction Bank, Bank of China is 3.90 yuan previously, in addition to Bank of China, the exchange payments to support the market funds are now all tied up.

Now, for the possible divestment shareholder Huijin, the bank shares the ups and downs no effect on its basic, it only depends on the number of dividend, in theory, of course, the more the better, why anti-Huijin The other way round?
Only one objective: to save up the market, first Agricultural Bank of China IPO.
However, as mentioned earlier, stuck on the gold exchange, there is no meaningful, even suffer losses, they have to maintain the stability of bank shares.
To attract foreign investment authorities for dumping to a vote of no war war vote or cheap to the market introduction of
Agricultural Bank of China listed on the stock reform appears to be “non-ordinary way to go,” the.

ABC did not intend to introduce in the market before the war overseas to vote, while the other three lines were introduced before listing overseas strategic investors, given the success of the three-line listing, the stock price rose over time, the banks, “or cheap on the” to be stir up public opinion, after bank shares dropping, this argument will be disappeared.
However, the disposal by sale of those who do not calculate: if I had three lines do not introduce war overseas investment, IPO is not successful, the banks will lose much?

Forced by public opinion, combined with major international financial institutions been hard hit by the financial crisis, trouble, the situation ABC special, available qualified overseas strategic investors, few in the end, ABC abandoned prior to listing the introduction of foreign war vote.
ABC selected the SEC in two days after Goldman Sachs as underwriters, Goldman Sachs announced the indictment.

Audit department listed in the Agricultural Bank of China before the ambitious plan, ABC released the audit of the management report violations. Then, the major media’s rampant speculation, this is a CCB, ICBC, Bank of China in particular before the listing, major newspapers, how is its scandal!

Fortunately, ABC did not introduce war overseas to vote, otherwise, this is a good bargaining chip foreign institutions. Will buy at lower prices ABC. , The media will shouted: ABC was sold to fraudsters had.
If the implicit guarantee of the ABC lost now listed in Hong Kong, some quite difficult, the media and agencies have the ABC impeccably no longer dark.
Is ABC really nothing you? Instead, ABC is the potential of the four largest banks in line.

Compared with the other three lines, ABC has the other banks do not have special advantages, first of all, ABC is the largest agency network, institutions that advantage, dot is money; Secondly, the Agricultural Bank of China serves the most broad, half of city, half in rural areas, can diversify risk; Third, the ABC will be the city’s largest bank-based income; Fourth, ABC will be the construction of new revenue the largest banks in rural areas; the five, along with central and local governments, tax and monetary policies on financial support agriculture tilt, ABC will get more preferential policies.
For these reasons, the four lines in the China Construction Bank has been in the rural layout.
Huijin holding stability and the stock market path

ABC suspense no longer listed, the only suspense is when listing what points are listed. The current malaise of the moment is obviously not a good time, some analysts had privately that the Agricultural Bank of China Shanghai Composite Index to 3,500 points in about the most appropriate, even that may be used as the final weapon to suppress spiking. However, these difficult to realize.

The other three lines were selected in the A share index of the high point of distribution, price-earnings ratio is high, price-earnings ratio is 24.23 times the Bank of China issued; ICBC trades at 27.34 times the issue; China Construction Bank issued trades at 32.91 times.

If the ABC in the current issue, difficult to achieve the expected price-earnings ratio of 20 times. Because the three-line price-earnings ratio is very low, bank stocks book value of the highest investment banks, but also the dynamic price-earnings ratio of 12 times.

“SAFE sure shot.” Central University of Finance and the China Banking Research Center, the Securities and Futures Tian Guo Yong, deputy director of the Institute to accept, “China Times” reporter, said that in his view, if the exchange that its holdings of gold The banking sector has been seriously underestimated, damaging its own interests in the case, surely shot.

Tian Guo Yong believes that the most important rescue SAFE strategy is to buy Bank of China, ICBC and China Construction Bank’s shares to stabilize market confidence, exchange money to buy other banks stocks Bu Zhiyu, because gold is not at the national level exchange stabilization fund “As to when shot, then see that the exchange when the gold holdings of the three lines are seriously underestimated. at any time may be shot.” In his view, the Department of dividend payments to reduce the impact of less impact on the market, direct holdings of shares in the three rows will help to restore market confidence, and to allow the three-line valuation more reasonable.

A market that market before the Agricultural Bank, will attempt to save the three lines, “because the three main lines have been seriously underestimated in the price. Agricultural Bank of China listed banking stocks need to return to reasonable levels.”

Polysilicon: a successful trial production of new silane method highlights the cost advantages

At present, the modified Siemens occupy in mainstream silicon manufacturing, but the process because of its high energy consumption in processing industry and popular criticism. In recent years, Chinese enterprises, speed up the improvement of polysilicon Siemens R & D and industrialization of the law rate for participation in international competition and also to explore new process routes, in order to grasp the low-power, low-cost polysilicon production technology.

“No problem! In 2010, will certainly be able to achieve PV power generation cost per kWh less than 1 yuan.” Recently, Yingli Group, the first 1GW solar cell module off the assembly line ceremony, the chairman of seedlings with students confidently told reporters. Seedlings with the confidence of students largely from Yingli’s 69 new silane Si Co., Ltd. Method polysilicon successful pilot project, low-cost polycrystalline silicon PV manufacturing will reduce the overall costs.

In previous years, the production of polysilicon has been controlled by European and American enterprises, polycrystalline silicon photovoltaic component in the cost share once the share reaches 70% in peak demand, polysilicon spot price close to 500 U.S. dollars / kg, while the international giants production cost is only more than 30 U.S. dollars / kg, huge profits into the accounts of the industry oligopoly. In recent years, the rise of domestic polysilicon manufacturer, so do not look at our PV business giant cue from abroad, but because of technological problems caused on the “high energy”, “high pollution” argument has been plaguing China’s polysilicon business . Chinese companies are exploring new process routes, trying to take off two hats, in the current view, the new law process is the closest silane successful attempt.

Remove them “high-energy hat”

Yingli Group Chief Strategy Officer Ma Xuelu in the “China Electronics News” interview, said that 69 new silane method polysilicon silicon industry project a design capacity of 3,000 tons / year, eventually will reach 18,000 tons / year. “69 Silicon chosen and most domestic polysilicon manufacturer of different process routes, is the first new technology to produce high purity silane polysilicon law firms.” Maxue Lu said, “the project’s production costs can be controlled within 28 U.S. dollars / kg or so, energy consumption indicator is better than the national standard. “

Ma Xuelu called “national standard” means in September 2009 the State Council issued the “State [2009] No. 38 document (hereinafter referred to as” article 38 “) in new polysilicon projects for the reduction of power consumption, integrated power consumption made limit. The document provides solar grade polysilicon to restore power consumption should be less than 60 kWh / kg, and clearly, to 2011, out of an integrated power consumption over 200 kwh / kg of polysilicon production capacity.

In fact, early release paper 38 prior to polysilicon manufacturing process “high energy” problem has attracted industry attention. Currently, the mainstream of the international polysilicon manufacturing process is modified Siemens process, even if the international polysilicon giant, Siemens, the use of improved production of polysilicon is also an integrated power consumption 120 kwh / kg, while some domestic manufacturers to use the technology integrated power consumption have reached “shocking” of 300 kWh / kg. Immediately press the Chinese Academy of Engineering, said in an interview, modified Siemens method using thermal chemical vapor reaction route, which is its high energy consumption, the root causes of the high cost of production. Although some domestic enterprises through technological transformation has been so integrated power consumption close to the international advanced level, but better than in the energy index of foreign competitors to achieve a breakthrough in the technological process is the inevitable choice. According to the staff of 69 silicon industry, the introduction of new silane in the process of production of polysilicon, the company currently uses the Siemens reactor, the power consumption of 75 kWh / kg; in the second phase of the project will using the fluidized bed reactor, its power consumption to as low as 25 kWh / kg, the production cost will be reduced to 22 U.S. dollars / kg.

Compared with the modified Siemens, 69 silicon industry, the new method of processing objects silane are also different. Modified Siemens process is the metallurgical silicon raw materials, metallurgy from the nature of the silica to silicon, but also requires a high energy consumption of the smelting process; and 69 new silane silicon industry of Direct to domestic resources as raw materials rich in silica, skip to silica for the metallurgical silicon smelting process.
Close to the closed-loop production

Another of the polysilicon production is accused of “high pollution.” Improved production of polysilicon with Siemens is the main by-product silicon tetrachloride, silicon tetrachloride, if not recycled, will cause great harm to the environment. “38 Man” also modified Siemens process specifically developed minimum standards for utilization of by-product recovery. The face of “high pollution” of the accused, the domestic polysilicon process using modified Siemens company he kept done an injustice, they believe that the mainstream companies have realized the closed-loop production, solve the silicon tetrachloride by-product recycling and other issues. This reporter learned that the stronger domestic polysilicon companies have done a really closed-loop production, but because of silicon tetrachloride recycling, especially low-power cold hydrogenation certain technological barriers, not all companies are capable of developing The technical capacity; However, as polysilicon prices fall, those who have not mastered the advanced recycling technology of silicon tetrachloride business will be difficult due to the high cost of survival.

The new law also facing silane product recall issues. According to Zhang, general manager of Silicon 69 months and introduction of new methods throughout the process chain silane intermediate products, such as hydrogen, silane, sodium aluminum fluoride can be recycled to achieve, the only non-toxic byproduct of sulfate — harm, and could be sold to other chemical companies as an industrial raw material. “Manufacturing will produce 1 kg 5 kg sulfate polysilicon.” Zhang months and said, “We have done market research, to June 9 silicon industry, scale of production, the production of sulfate is negligible, the domestic chemical industry can be completely digestion. “

In product quality, the new law, the performance of silane is also gratifying. According to Zhang month and said the new technology of production of polysilicon silane law in resistivity, minority carrier lifetime and the metal content, and many other indicators are better than the Siemens process improvement. “69 successful trial production of silicon industry, not only will lead to technological upgrading of domestic polysilicon industry, and will push our silicon to high purity silicon as a starting point to develop the industrial chain.” Maxue Lu said, “69 not only the production of silicon photovoltaic industry polysilicon, also the production of electronic grade polysilicon, China integrated circuits, power semiconductor devices to provide raw materials industry. “Of course, only made the company successful trial production, mass production expected in mid 2010, when from the market to test 69 silicon industry innovations.

Chinese enterprises should seize the opportunity to catch up

Silane law with new technology to replace modified Siemens process, is the company catch up with international advanced level, a great opportunity. According to Academician immediately heard a few years ago the price of polysilicon soaring to the modified method of international polysilicon giant Siemens has brought huge profits, but also enable them to produce an innovative inertia. Shi Wen said: “In the early 80s of last century, plasma enhanced chemical reaction method in coating industry has achieved great success; in the mid 80s of last century, microelectronics industry using PECVD (plasma enhanced chemical vapor deposition ) successfully produced amorphous silicon thin film. However, the improvement of the international Siemens company did not initiate the law to apply these research and commercialization. “Miao told reporters that even the students, the future Silicon 69 will transfer to the maturity of new domestic counterparts Silane method technology. Therefore, if Chinese enterprises grasp the opportunity to low-power, low-cost new silane law as a breakthrough in the polysilicon industry is likely to come from behind the international competition.

In fact, the domestic law of silane try this new breakthrough on the road more than the British company a profit. Hubei Wu Silicone New Material Co., Ltd. Tai, general manager of Tri to the “China Electronics News” reporter introduced his proposed “the establishment of alkoxy silane-based polysilicon industrial system,” the idea of their chosen process route is: chemical reaction of silicon with alcohols to generate four direct silanes, and then to 4 alkoxy silane as raw materials, and advanced with the sol-gel synthesis of high purity silica granulation technology, the last use of the carbon thermal reduction method, the Under certain conditions, high purity silica with ultra-pure carbon reduction by polysilicon. Tri said that with the production of polycrystalline silicon alkoxy silanes, modified Siemens process energy than 60% -80% lower; alcohol used in the production process instead of chlorine, environmental problems easier to solve; the same time, will reduce its production costs to 20 U.S. dollars / kg less. “At present, the alkyl silane polysilicon production of all major process steps are still in various stages of industrialization, is expected to be completed within 3 years the process of industrialization.” Tri said.
