Suzhou-made high-performance amorphous silicon solar cells
Development of green and marked a new low-carbon energy technology industry, economic transformation and upgrading of Suzhou is undoubtedly an important part. The new energy industry, inexhaustible solar energy, new energy industry is aiming good focus.
Some people say that solar energy solar energy, with the sun, there can be no sun on the incompetent.
This is only half right - before it does, now is not right, even in rainy days under fluorescent light, a solar cell can still generate electricity. This battery is also used to promote fruits and vegetables grown in greenhouses, very broad application prospects.
This solar cell is the high-performance amorphous silicon solar cells. Recently, the production of this battery of common photovoltaic energy (Suzhou) Co., Ltd. has been in Weiting within the foundation, a completed, will form a 50-100 megawatt amorphous silicon thin film solar cell production capacity, long-term production size of around 200 MW, while the establishment of advanced technology research and development, testing and building integrated and efficient agricultural development center three centers, become the leading enterprise in the field of solar energy industry.
Launched under the electric lamp
Universal Solar Energy (Suzhou) Co., Ltd. Dr. Liu Youhai introduced into the 21st century, global demand for solar cells, are more than 40% annually.
The current silicon solar cells can be divided into three categories: single crystal silicon solar cells, polycrystalline silicon thin-film amorphous silicon thin film solar cells and solar cells. Among them, a dark look of polysilicon thin-film solar cell market share of 90%. However, polycrystalline silicon thin-film solar cell production requires large amounts of high-purity silicon, and high purity silicon in short supply in recent years, there is no market price were even seriously affected the development of the industry. In addition, the production of polycrystalline silicon thin film solar cell itself is energy consumption, to produce a polycrystalline silicon thin-film solar photovoltaic module components (1 × 1.5 s specifications), you need to consume 40 kg of coal, but also pollution.
Amorphous silicon thin film solar cells do not exist these constraints. Of course, before the battery is also not high energy conversion rate of the shortcomings. Liuyou Hai said that the general polycrystalline silicon thin film solar cells, energy conversion rate of 16%, while the amorphous silicon thin film solar cell conversion rate of only 7% of the world's advanced level of only 10%. Conversion rate is low, so many people are reluctant to choose this cell.
However, after the Chinese team of independent research and development, General Solar Energy (Suzhou) Co., Ltd can produce energy conversion rate of 14%. Listen to less than polycrystalline silicon thin film solar cells, but the scientific tests proved that the same conversion rate of thin film solar cells, amorphous silicon of the electricity is 1.2 times that of polysilicon. Liu Youhai explained that this is because the amorphous silicon cell in the case of relatively weak light can generate electricity, such as the rainy day (with a little light), even under fluorescent light can also generate electricity.
Sure enough, the reporter in the general solar energy (Suzhou) Co., Ltd. for temporary office point to witness this: Here's a light in the corner stood a near-adult height of the plate, the surface looks like a glass plate, close to the top sheet of paper to tell people that this is the amorphous silicon thin film solar cell components. Qi is the entire component connected with the outside world without wires, but also shine a trace of the sun, but even the top of a small lamp lit. Accompanied by the companies interviewed Yan One project manager explained before, a small electric light power is absorbed by the interior components of energy conversion from the fluorescent lamp.
Unlimited prospects
Liu Youhai not without pride, 14% by 1.2 to 16.8%, so their battery power, the actual conversion rate is higher than ordinary silicon cells. This battery can be used for power plant power generation, can also be used to help energy efficiency in buildings, but also for home use, such as used in water heaters, and for lighting. Components by a 100-120 watt power, ordinary people generally coupled with a board with six battery unit is sufficient.
In addition, the battery can be used in greenhouses, the wavelength is not so certain generation, and used to greenhouse warming, promote fruit and vegetable production, which is the normal silicon cells can not. Liu Youhai, at present they have other places in Rugao established several demonstration studio, model studio is not installed on a plastic film holder, but fitted with amorphous silicon thin film solar modules. Because there is no sun can still generate electricity, so cold, when fruits and vegetables grow much faster rate than other greenhouses.
Liu Youhai said, is optimistic about the bright prospects, coupled with a favorable investment environment in Suzhou, so the total investment of $ 300 million, covers an area of 253 acres of foreign-funded projects in Suzhou, the foundation, a project is expected to put into operation next year . In addition to the construction of thin-film PV production base and the control group production equipment manufacturing base, there will also set up three R & D centers, 30,000 square meters of advanced technology research and development center, 15,000 square meters of high-efficiency agriculture test center and 15,000 square meters of building integration and development center.
Ambitious new energy industry development
As a high-performance products, amorphous silicon thin film solar cells is certainly leading the development of a new energy industry, beach-goers, but by no means the only beach-goers.
To the park, for example, here have been aimed at this new energy photovoltaic nanotechnology industry. Nano-optical semiconductor lighting and new energy is the main direction of solar photovoltaic cells, to general lighting, large screen LCD LED backlight and battery equipment as a breakthrough independent film.
And General Photovoltaic Energy (Suzhou) Co., Ltd. founded in the park the same day over bright electronic items, is one example. The company from Taiwan BenQ Group Electronics Co., Ltd. a subsidiary of Lunda investment, total investment of about $ 500 million dollars. The project covers about 363 acres, will be moved to the first quarter of next year and production equipment to provide domestic and international markets LED backlight LCD panel and LED lighting applications. After the completion of up to bright electronic LED industry will become only the wafer from the upstream, midstream chip, downstream packaging to stop production of business applications, the formation of the mainland's largest LED industry base.
Settled on poly-Chan Loufeng Optoelectronics Technology (Suzhou) Co., Ltd., is one example. The company by Gu Xin Photoelectric Co., Ltd. on April 8, 2010 funded the establishment, mainly engaged in high-power semiconductor lighting (LED) epitaxy and chip design industry. Companies registered capital of 250 million yuan, total investment of 750 billion yuan.

Yingli Group's solar technology deep into the American Campus
Yingli Group's solar technology deep into the American Campus
According to Bloomberg, China's second largest domestic manufacturer of solar panels - Yingli Green Energy Holding Company Limited (Yingli Green Energy Holding Co.) Rutgers University has for the United States (Rutgers University) supplied the 7600 solar panels, by the light energy conversion power generation, $ 10 million this year, this project can save the school $ 200,000 in energy costs. Rutgers University has become the nation's largest campus solar one.
It is reported, including British interests in China, including several solar panel manufacturers to slash production costs due to successful make a template of international solar cell prices declined by 50% within two years. Affected by this trend, the global solar power applications are also within the scope has been further promoted.
SunDurance Energy CEO Buckman (Al Bucknam), said: "Compared with other companies, Yingli Group more price advantage."
At present, solar PV panels company cut the price move has also been supported by the Chinese government. Some analysts have pointed out that the Chinese government's move to support the Japanese government with decades ago, the practice of the domestic electronics industry is very similar, and in that period, the rapid development of electronics industry in Japan, Japanese companies have now become a major international power electronics markets. Element Partners investment firm Maikejindi (Kathleen A. McGinty), said: "The Chinese government's support of solar energy manufacturers of solar cells is to guide the rapidly falling prices template, the main reason."
Research and consulting firm Pike Research 6 report released Tuesday said that by 2013, there will be a part of the global market situation, that is, the cost of solar energy in conjunction with normal grid electricity as cheaply. European Solar Industry Association (European Photovoltaic Industry Association, EPIA) had also expected in 2010, when parts of southern Italy, in conjunction with grid electricity generation cost of solar flat, followed by Spain in 2012, some areas can reach this goal .
Bloomberg's New Energy Finance Consulting (Bloomberg New Energy Finance) said that, because of price advantage, in the past six years, the Chinese manufacturer of photovoltaic panels in the international market share has gradually increased to the current 43%.
Negative impact on
Consulting firm New Energy Finance analyst Deni chief solar Chase (Jenny Chase) said: "The large number of solar manufacturers in Asia, this factor will make the international market price of solar panels to further decline."
However, the solar panels price decline will have a negative impact on makers that investors are reluctant to invest, so now most of the solar energy company's stock has not been good.
At present, China's domestic companies, including large-scale solar energy Suntech Power Co., Ltd. (Suntech Power Holdings), Yingli Group and Trina Solar Limited (Trina Solar Ltd.). This year, three companies in the New York Stock Exchange stock prices are different degrees of decline, which Suntech most serious decline of 37%.
Compared with solar energy enterprises in China, foreign manufacturers, such as the German solar giant SolarWorld AG, the U.S. solar panel maker Evergreen Solar Inc.'s Stock devaluation is more serious, the latter's stock price as of July 21 has dropped 56 %.
China's subsidy policy
Deloitte China Research and Insight Director of the Centre Du Zhihao (Kenneth J. DeWoskin) that has been widely believed that China's rapid development of solar energy companies have been able to, mainly because of support by the government. However, this practice was eventually overshadowed the value of PV panels should be.
Yuanta Securities (Yuanta Securities) of the energy industry analyst, said Li Min, China's solar energy business in the international stock market compared to foreign companies, or more attractive. In general terms, the basic analysts believe that China Solar solar energy companies in other countries more than investment potential.
Prior to a Bloomberg News survey of 27 analysts, 14 bits are recommended to purchase Yingli shares, only one analyst thinks the stock should be sold Yingli. In contrast, only three analysts believe that stocks should be purchased Evergreen Solar, and the proposed sale of the company's stock to seven the number of analysts.
China is only the beginning of the development of solar energy companies
Currently, there are some cities in China began the implementation of subsidies for solar energy, and these cities for renewable energy applications to speed up the pace. Baoding subsidies enacted attracted about 200 renewable energy companies to invest.
Earlier, China's State Development Bank (China Development Bank Corp.) Declared during the year will Yingli, Suntech and Trina Solar to provide solar energy totaled 116 billion yuan (about $ 17 billion) in loans. Beijing also plans to install the 2012 contract prices to reach $ 1 billion in solar panels for heating and lighting systems for the city to provide energy.
Bank of America Merrill Lynch (Bank of America-Merrill Lynch) analyst Lu Yeung in Hong Kong, said: "The Chinese Government is carefully reviewing its energy policy and the need for new measures." Vice president Jason Liu Yingli, said: "China to promote the the solar industry is still in the initial stage, the use of renewable energy is the inevitable development.
IEA (International Energy Agency) data released in 2009, China replaced the U.S. as the world's largest energy consumer. Thus, the Chinese government has tried to build more similar to companies like Yingli Group to reduce the country for oil imports and the demand for coal. In addition, in 2009 the Chinese government invested $ 34.6 billion for clean energy projects, almost twice the amount of investment the U.S. government.
Promising solar cell recovery
Photovoltaic industry started to recover from the end of last year. From the fourth quarter of 2009, the PV market has gradually regained consciousness and development. A standard commercial solar PV panels can be 12% -18% of solar energy into usable electrical energy, and high-end model of efficiency up to 20%. The first half of this year, form a good supply and demand constantly.
Solar cell industry sales from the demand for raw materials in the polysilicon can be seen. , The Investment Advisory Industry Research Center, the latest data can tell us, GCL in the January to May this year, 5713 tons polysilicon production and sales, compared with an increase of 300% over the same period last year. Only from January to May, China's total import volume of polysilicon to 1.55 million tons, compared to last year, an increase of 121%. This data can also be known as second only to solar PV production base in Jiangsu, Zhejiang, the first quarter of this year, total exports of solar 4,730,000, an increase of 250%.
The capacity of the global market also continued to expand, not only in some European countries to step up photovoltaic project, European governments also preferential policies to support enterprises to develop solar photovoltaic industry. United States, Japan and other countries are actively layout. China also announced in June this year the second batch of PV tenders, totaling 280MW, more than last year 270MW. It predicts that the global PV installed capacity will double last year. This is also for the country's PV industry has brought new growth points.
