"Cold" eyes on the sidelines of solar cell market circles, something wrong

Introduction: the German "Handelsblatt" reported on the 18th, two years of international silicon prices have fallen sharply, from 500 per kilogram to $ the current less than $ 50. All this seems to have originated from an oversupply of polysilicon industry the past two years, "excess capacity", "cost-benefit", "prospects" and once again become the solar photovoltaic industry focus.

Polysilicon is a "true excess" or "to be excessive."

Under the State Council issued "on the inhibition of excess capacity and duplication of the notice", the wind power equipment and two new major energy industry polysilicon was first included in the repeated construction of the column. Ever since, the original mission to promote industrial restructuring, new energy has become the object of being adjusted; and environmental protection for the purpose of the original Fengjie to polycrystalline silicon photovoltaic materials to be labeled anti-high energy consumption, high pollution, the label - for a time, China's new energy industry, as if trapped in a Gogol-style satire.

Production of silicon solar cells as the main raw material supply bottlenecks occur in 2007-2008, due to surge in demand for solar energy industry, silicon became a scarce resource. But the financial crisis and other factors, on the one hand the current solar industry growth than expected, Germany and Spain began to cut subsidies for solar power, solar power in 2009 new peak in 2008 was only 1 / 4. On the other hand, launched two years ago, rush silicon production project has been put into operation one after another, the output is growing, contributing to the current oversupply of silicon. Market analysis firm iSuppli to a study in 2009, the actual needs of the global silicon production more than 44,000 tons. With the more projects into production, silicon oversupply will worsen. While Italy, the United States and other countries will be the new solar energy market, but still not enough to offset the expansion of silicon production capacity. iSuppli predicts 2011 global production will exceed 200,000 tons of silicon, silicon needs of 14 million tons of surplus production increased to 60,000 tons.

Ministry of Commerce will limit polysilicon processing trade exports and open a "medicine." However, even if long been branded a "surplus" mark, the polysilicon industry, "is excess" argument is heard.

NDRC Energy Research Institute, Centre for Renewable Energy Development Ren Dongming, Deputy Director: "From the future development, the polysilicon is not necessarily true surplus, China has not yet form a complete solar power price mechanism, the domestic market does not start, solar cell applications prospects are not clear. "

Strategic Research Institute under the Ministry of Science and research shows that while polysilicon capacity expansion soon, but because of the construction cycle and the reasons for fluctuations in the market, has been in short supply, large gaps still need to rely on imports to fill. Semiconductor equipment and materials from the National Standardization Technical Committee data show that in 2009 actual production of polysilicon is only 14,000 tons, and imports were flat.

Broker is expected to show that the mainland's polysilicon production in 2010 up to 45,000 tons, semiconductor and solar cell totaling 44,960 tons of polysilicon, polysilicon supply and demand balance; domestic battery production in 2011 will grow 40 percent to 7168MW, at 7.5g / w calculated take 53,760 tons of polysilicon, assumed to be polycrystalline semiconductors up 25% to reach 5,000 tons, the total domestic demand for polysilicon to 58,760 tons, domestic production is expected to reach 800 million tons, the pressure of oversupply.

For the emerging understanding of the industry should not be the same in some mature industries, for their 'surplus' should be taking a tolerant attitude. Capacity growth of new industries, for a perspective means that the attention and access to capital, this just shows there is a breakthrough development of the industry and upgrade possible.

Polysilicon prices are no longer return to the old value of profits is inevitable

The price of polysilicon in 2008 are crazy hard, and gradually return to the value of the industry's consensus. It is reported that the domestic tax price of 410,000 -42 yuan / ton, is expected to slow as demand for photovoltaic cells, the urgency of the demand for silicon material decline in the second half of the silicon material price pressure. The brokers report that, with the polysilicon production technology breakthrough, the domestic silicon material costs will decline; photoelectric conversion efficiency as well as silicon materials cutting technology, the battery unit will reduce the amount of silicon, the long-term prices will return to value.

Second, the new energy technology revolution there are many variables. For example, crystalline silicon cell industry expected conversion rate in recent years from 17% to 20%, such as the use of new technologies and new materials, the efficiency of even this can be increased to 30-50%.

The conversion rate of solar cells increased by one percentage point each, the cost will drop 7%. Just think, if the next breakthrough in the field of photovoltaic technology innovation, and its cost has dropped significantly to the price even lower than the thermal power with thermal power costs, the resulting active market capacity will be "infinity."

Long-term view, then, today Jiang Yi's production capacity will then develop into tomorrow's bottleneck?

Moore's Law in the solar cell industry

Little knowledge of the IT people will not be bound to the world-famous Moore's Law, Intel founder Moore gains, the fact that, Moore's Law still has vitality today, but not limited to the IT industry, representatives from the solar The same applies to the new energy industry.

According to Moore's Law, with the advancement of technology, industrial technology matures, the cost of solar power will become more affordable, and ultimately achieve even without subsidies can also be competing against traditional fossil fuels situation.

However, the chip and solar panels on the surface but there are similarities. Both involve silicon and electricity, some processing techniques are the same. However, the production of solar panels is much simpler, and high yield. A factory can produce 3000 per hour, usually silicon wafers, each wafer to form a solar cell. By contrast, the modest size of a semiconductor plant may be a year to produce 200,000 chips. This is a high accuracy of the industry, because each chip can be made of 10 million chips.

Photovoltaic power generation is the use of solar cells solar energy into electrical energy, can be used independently, but also to the grid. The rapid development of China PV industry in 2000, only 3 MW solar cell production, the end of 2007 to 1088 megawatts, ranking first in the world.

Stock market: the new energy sector prospects

China's economy in the long run, the theme of the new energy sector is very obvious characteristics, duration and space longer.

Recent fundamental changes in the new energy sector, we believe that policy is still more obvious bullish signal, expected volatility of investment opportunities. The new energy sector in the A-share market is relatively large plate, cover wind, solar, nuclear, energy-saving materials and other fields. New energy as China's economy to achieve the promise of low-carbon development goals important force in recent years has been attached great importance to the national level, the relevant industrial policies intensive. The present stage, we believe that the new energy vehicles, new energy battery two segments may be a greater chance of volatility, the policy faced many benefits can be expected.

New energy battery will benefit from new energy vehicles, electronics tech and other long-term benefits of technological innovation. Online Chinese government published a "State Council on further intensify its efforts to ensure the realization of" five "emission reduction targets," which pointed out the need to continue to work out a new energy vehicle demonstration. Relevant to the end of May before the introduction of specific implementation details, this time limit is approaching. New energy official launch of the automotive market, both in terms of the whole industry chain development opportunity. As the future mainstream car battery lithium ion battery industry will face more background to promote interest. We are optimistic about the potential for species in which the volatility of the opportunity. Such as the Vosges stake Corun, Desai battery billion Wei Li and so on. The reason we are concerned with the volatility of the opportunity stage, mainly on account of the overall market will continue to be weak, but the policy context of profitable opportunities for the species is more volatile performance of the probability of large.

First use of pure biofuel flight test aircraft completed

8 in Berlin - Brandenburg International Aviation and Aerospace Exhibition, the European civil aircraft manufacturer Airbus (Airbus) to complete the international coalition led by the world's first use of pure biofuel flight test.

June 8, "a new generation of Diamond DA42" aircraft with 100% of algae biofuels, took part in the flying display. This is the first demonstration of bio-fuel technologies can supply energy for the aircraft. The success of this test confirms keen to develop bio-fuel efforts of engineers, and encourage them to conduct further research to reduce aircraft adverse effects on the environment.

Airbus owner EADS (EADS), said a specific type of algae oil can be extracted with higher levels of this algae bio-fuels made from conventional jet fuel than the energy provided by a higher, but also in the more marginal lands or waters contaminated growth.

Air quality measurements showed that the traditional oil extraction compared to emissions generated by kerosene, algae biofuel emissions of hydrocarbons contained in the eight times less. Airbus also said that the algae biofuel produced by nitrogen oxides to 40% less sulfur dioxide generated even less, this is because, compared with fossil fuels, bio-materials have been included in the composition of nitrogen and sulfur content on much less.

Seaweed is now seen as the most promising source of biofuel, because compared with other biofuel sources, such as Jatropha or Camelina spp, algae need to grow up less space. In the past two years, airlines have been tested three bio-fuels, including Air New Zealand, KLM Royal Dutch Airlines and Japan Airlines, but they are in the test of these bio-fuels and jet fuel mix used .

Berlin - Brandenburg International Aviation and Aerospace Exhibition on display in Berlin, Germany, from 8 until 13.

BYD F3DM low carbon version of the battery

BYD F3DM version of the battery is low carbon iron batteries, production, use very little pollution in the process.

It has three highlights: First, run away, a pure electric mode can run 60 kilometers. The second is energy, need fuel to run a car only 1 / 5 of the cost; third performance, BYD dual-mode electric vehicle F3DM low carbon version of the maximum output power of 125KW, 2.4L engine with equivalent power performance.

You can recharge at home. Family charge, 7 hours can be filled. Professional Charging Station can fully charge half an hour, 10 minutes to charge 50%. It also has a roof of solar battery charging system, charging by solar energy stored in the iron batteries.

Life, the body is said to have opened scrapped BYD F3DM low carbon version of the battery are also available. But some people used to know.

Teach you to identify good or bad charger

Market, the so-called universal fast charge, voltage 4 ~ 6V, current 0 ~ 700MA. Strong charging voltage high-current fast pace of course, but too easily lead to the battery current from the drum to shorten life, but high current will have a great heat, the temperature is too high is easy to cause the battery to explode, this is the most serious security risks. 2 years ago there have been several since the summer temperature is too high, resulting in cell phone battery explosion injured person's news, we are interested can look around, security is really not a joking matter. From this we can conclude that: charger is not charging faster, the better.

Since the explosion of the battery temperature is too high and the news, many manufacturers have made changes in power output, increased the pressure limiting current limiting resistor, this voltage and current are under control, the temperature is not high, but the voltage is too low , the battery can not be filled, with a half-day one day one charge no electricity, or now charge a high capacity battery has fully satisfied for 1-2 days, after a long time to reduce battery capacity and affect life. Recommend the use of big brand manufacturers such as chargers, through land and sea, flying hair back and so on. Recently the market has out a new universal charge, Bo Tao, Hiromi Department of brands, listening to people say that if manufacturers in Shenzhen Bognis technology, the factory in Sakata. Bo Tao of the three light charger and the charger I bought colorful tested, electrical properties are very good, in the standard range, and flying hair back, land and sea through the neck and neck and other major brands. Cattle do drop more, 1 m 5 times, completely OK, a little shell rupture, 2 meters or 5 times no big problem. Still down from the fourth floor, the shells are rotten, basically in a naked state, and Jianhui Lai power a test, actually electrical properties without any problems, carefully looked at the electronic components and solder joints, really solid material. Ordinary universal charge and do not to mention still falling, and a little spot on the fall off, the machine will not work. The only regret, Bo Tao colorful appearance actually an old-fashioned egg-shaped, very beautiful, looking forward to the future it will be more beautiful appearance. Price than the flying hair back, land and sea through cheaper, cost is very high, it is recommended to try next.

Zheng Yonggang: the field of lithium battery materials, the introduction of Japanese technology

Yesterday, the third China Open Forum held in the theme of "foreign investment and China's industrial restructuring and revitalization" of the industry summit. Shanshan Zheng Yonggang Group Co., Ltd. attended the forum and delivered speeches. Zheng Yonggang in the reporter's interview after the speech, said Chinese companies, including companies, including Ningbo, do not lose the opportunity to pro-climbing, together with Fortune 500 companies, with an open mind to learn from them, will be a win-win results.

Zheng Yonggang disclosed yesterday that he was at the helm of the Shanshan Group, the clothing section in the beginning of last year with Japan's Itochu to achieve the marriage of the introduction of Itochu, this Fortune 500 business management experience. Next, the Shanshan Group, lithium battery materials sector, will be "copy" of this approach, with the industry-leading Japanese companies within the technology cooperation.

Zheng Yonggang told reporters, Shanshan 10 years ago to enter the lithium battery industry, the United States, Germany, Japan counterparts basically the same starting line, now Shanshan Li-ion battery materials, manufacturing scale has become China's largest, but technically much far behind the world advanced level. This disparity is that Firs time in 10 years to focus only on the size of the expansion, but not go more in-depth technical research and development, while Japan's giant lithium battery cathode materials technology company in the technology Toda take a "generation of R & D , reserve generation, application generation "strategy. Toda has now become the field of lithium battery cathode materials most technologically advanced enterprises, and new energy into the symbol field symbol of revolution - automobile battery in the field. Faced with this gap, Shanshan in Itochu's matchmaking, and Japan's Toda technical cooperation, the two sides will set up a joint venture company for production. "We will combine the size of Shanshan, Toda's technology, 'the largest and leading' the target, thus the low-end products from the areas of mobile phone batteries to automotive batteries to upgrade." At the same time Shanshan Li-ion battery anode material and a Japanese giant is also seeking to cooperate to solve technical bottlenecks, Shanshan Li-ion battery industry chain will be the most extensive coverage, most technologically leading and largest companies.

Battery into the biggest security risk of electric cars on the road ahead

Experts warning the battery hidden ---

In March, in Huaibei, Anhui Province Lieshan Guraozhen Mountain North village a village on the road, an electric bike from moving suddenly exploded, the rider was killed on the spot. The investigation, resulting in the explosion is mainly due to the battery electric bicycle parts. This can not help but think about the road electric vehicles. Most of these vehicles and electric bicycles using the same lead-acid batteries or lithium batteries, electric cars began to be an explosion hazard mentioned many experts in the industry.

Experts confirmed to reporters that if the gasoline car as mechanical power equipment, electric vehicles are completely electromechanical integration equipment, its storage mode, the vehicle driver in the form and structure are all closely related with the safe use of electricity. Electric vehicle battery internal pressure is too high, over-charging the battery may cause explosion. Battery voltage is too high, once the leakage would seriously harm the human body; strong acid, strong alkaline electrolyte leakage when it is easy to burn crew ... ... the security of electric vehicles depends largely on battery safety.

When a community focus have to look at charging stations, vehicle mileage, battery life and recycling issues, the safety of electric cars has been affecting the government, the power sector and the automotive, battery manufacturers nerves, since 2001 on the introduction of standards.

Conditions change resulting in an explosion

Lead-acid, lithium ion, sodium sulfur, nickel-metal hydride batteries used in electric vehicles and so on. Lithium-ion batteries because of light weight, strong power, by most car manufacturers of all ages. Lithium-ion battery can be divided into Fe-phosphate, manganese, aluminum and other acid. No matter what kind of vehicle batteries, battery structure is basically the same - from the electrode, electrolyte, membrane, shell and cover components. Therefore, the battery can be seen as a closed container. Under normal circumstances, the pressure inside the container closed properly. But when the battery is subjected to shock, the pressure may exceed the limits of the battery case can bear, which exploded.

Lithium battery charging, the cathode of lithium-ion will be transferred to the anode within. When the excessive accumulation of negative lithium ion, lithium-ion will overflow to produce dendritic crystals. The spread of crystal growth, punctured diaphragm, so that positive and negative contact, it will cause a short circuit in an instant release of large amounts of heat. Electrolyte burning heat, then boil, causing the battery to explode.

Lead-acid battery charging hydrolysis may occur later, that water molecules break down into easy-to-burning hydrogen and oxygen combustion of the necessary material. At this point in time if the safety valve does not open, the possibility of a large battery explosion. It is understood that the nickel-cadmium batteries, nickel metal hydride rechargeable batteries are likely to arise because of excessive hydrogen. Sodium sulfur battery at work, must be in the high-temperature molten sulfur, battery temperature will reach 350 degrees Celsius, then sulfur may evaporate. These may cause battery explosion, burning.

High pressure resulting in leakage, fire

Compared to gasoline vehicles, electric vehicles, electrical equipment more, and require high voltage to maintain the drive motor. To reduce power losses in the transmission of energy, pure electric vehicle battery voltage is higher, usually the largest human safety voltage (36 volts) 10 times; hybrid vehicle battery voltage is low there are 144 volts. Battery in the event of leakage, electric shock and other accidents, the crew will be a greater harm.

The car is running, there will inevitably be parts of the inter-collision, friction, squeezing, which may appear damaged wire insulation, terminals overlap with the emergence of the surrounding metal. These may lead to leakage and short circuit, electric shock hazard to occupants. Short-circuit current will produce significant amounts of heat, electrical conductors overlap each other resulting spark may ignite surrounding combustible materials, causing the vehicle on fire.

Electrolyte burns occupants

Severe shock when the battery, the battery case may break, causing electrolyte leakage and a lot of splashing. Electrolyte is usually strong acids and strong alkaline substances, such as lead-acid battery electrolyte is dilute sulfuric acid, nickel-chromium, nickel-metal hydride battery electrolyte is a corrosive sodium hydroxide solution and easy. Electrolyte leakage and splashing occupants may be severely burned.

Factory operations

Traffic Accident

Is the biggest hidden trouble cause the battery incident

Although the major research institutes, automobile manufacturers to reduce the battery system for damage on the human body a series of efforts, such as a battery to increase over-voltage protection, etc., but electric vehicles to go on the road, with the traditional gasoline car is no different - rub , rear-end collision, crash, rollover and other accidents occurred in the gasoline car, electric vehicles are likely to occur, and damage to the vehicle accident unpredictable. In line with national standards of electric vehicles still exist that explosion.

The main battery to prevent accidents by installing a fixed location and methods to solve. Battery electric vehicles equipped with centralized and distributed two main forms. Centralized installation is to concentrate all the batteries installed in a location of electric vehicles. This form has the advantage of using a short wire can connect the battery, reducing the risk of leakage of wire and wiring clear. Sometimes by the body structure and size limits, the battery is difficult to be arranged in the same location, so some models based on spatial structure must attack to install the battery, that is to take distributed installation, but must use a long wire between the battery connection, increasing the risk of leakage, and not easy to repair. No matter what the layout of the battery using the form of wire insulation are likely to fall off by the aging and effects of the accident, resulting in leakage.

Electric vehicle battery manufacturers want to give a reliable constraint, the batteries placed in battery bay. Battery holder and some from the angle, welded steel bars, etc.; some use special stampings. However, the vehicle operating conditions is very complex, and down bumpy, sharp turn and jitter are inevitable. Battery between the battery and other objects may also occur between the friction, collision, compression, causing the battery cable off, broken wires or batteries wear electrolyte leakage.

Reporter's notes

Consumers should be aware of the danger warning

Early in the morning, go to work, to launch electric cars, not hear any engine noise in the quiet and listen to those music shuttle in traffic, not worry about traffic jams bring high fuel consumption, do not have to concern the oil tank is running low and busy looking gas stations, relax and arrive in company with the car parked in the parking charge on the pile, charging, and then began a busy day ... ...

This scene was a lot of auto companies used to introduce the next few years the arrival of electric vehicles may live, even if living at the beginning of Shihai quite small minority, but has been the automotive industry that is the future direction of car development. When the average consumer due to car manufacturers of electric vehicles painted intoxicated life, longing, they did not know this seemingly perfect way to travel is not perfect, making this a better picture of people seem to forget to point out, the key to zero electric vehicles components - the battery, there is an explosion hazard!

This is not a new discovery reporters, industry experts, automobile manufacturers are well aware of R & D personnel this risk. During the interview, insiders put it bluntly, electric cars may run on the road a time bomb. Although this statement exaggerated, but gave away the beauty of electric vehicles, under the guise of a fatal drawback, but due to the current electric car has not really into people lives, their explosion hazards also exist only in the professional concerns or questions in the media manufacturers, no specific examples as evidence, there is no one willing to risk this made public, the only analogy is that the high incidence of fire bombings of electric bicycles.

Think of ways to hide a dangerous occurrence or remedy, or there is risk informed in advance please be careful? This should not be difficult to answer multiple-choice Road.

Government measures

46 electric vehicle safety standards

Up to now, the state and the automotive industry has introduced 46 standards for electric vehicles. These standards related to electric, hybrid and fuel cell vehicles and other electric vehicles, the vehicle, key parts, charger, charging station and charging interface has specific requirements. China Automotive Technology and Research Center, Chief Engineer Chou standard is the standard one of the drafters, he said: "There is no standard outside world that electric cars are not right in fact, in 2001 there are six criteria introduced; end of last year, electric vehicles standard has reached 42 this year, added four. "It is understood that the four criteria introduced this year include the" electric vehicle conductive charging interface "," electric vehicle battery management system and non-vehicle communication protocol between the charger. " , "General Requirements for electric vehicle charging station" and "light hybrid electric vehicle energy consumption test methods."
