high-performance amorphous silicon solar cells
Development of green and marked a new low-carbon energy technology industry in Suzhou economic restructuring is undoubtedly an important part of upgrading. The new energy industry, dell GK479 inexhaustible solar energy, new energy industry is a good key aim.
Some people say that solar energy solar energy, with the sun there can be no sun on the incompetent.
This is only half – before it does, not right now, and rainy days, even under fluorescent lights, a solar cell can still generate electricity. This battery can also be used to promote fruit and vegetable greenhouse growth prospects are bright.
This solar cell is the high-performance amorphous silicon solar cells. Recently, the production of such batteries General PV Energy (Suzhou) Co., Ltd. has been in the park within Weiting foundation, one completed, it will form a 50-100 megawatt amorphous silicon thin film solar cell production capacity, long-term production size of around 200 MW, dell FK890 while the establishment of advanced technology research and development, testing and building integrated high-efficiency agriculture development center and three centers, become the leading enterprises in the field of solar energy industry.
Under fluorescent light power launched
Universal Photovoltaic Energy (Suzhou) Co., Ltd. General Manager Dr. Liu Youhai introduced into the 21st century, global demand for solar cells, being more than 40% annually.
The current silicon solar cells can be divided into three categories: single crystal silicon solar cells, polycrystalline silicon thin film solar cells and amorphous silicon thin film solar cells. Which looks rather dark polysilicon thin film solar cell market share of 90%. But the production of polycrystalline silicon thin film solar cells need to consume a large amount of high purity silicon, and high purity silicon in short supply in recent years, there were even no market value, serious impact on the industry. dell Inspiron 1721 battery In addition, the production of polycrystalline silicon thin film solar cell energy consumption, to produce a polycrystalline silicon thin film solar photovoltaic module components (1 × 1.5 米 specifications), needs to consume 40 kilograms of coal, but also pollution.
Amorphous silicon thin film solar cell is not the existence of these constraints. Of course, before the existence of such batteries is not high energy conversion rate of the shortcomings. Liu Youhai that the general polysilicon thin film solar cell energy conversion rate of 16%, while the amorphous silicon thin film solar cell conversion rate was 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 R & D, General PV Energy (Suzhou) Co., Ltd can produce the energy conversion rate of 14%. Listen to less than polycrystalline silicon thin film solar cells, but scientific tests proved that the same conversion rate of thin film solar cells, amorphous silicon The electricity is 1.2 times that of polysilicon. Liu Youhai explained that this is because the amorphous silicon cells are more weak in the case of light can generate electricity, such as rainy days (if a little light), even under fluorescent light can also generate electricity.
Sure enough, reporters Universal Photovoltaic Energy (Suzhou) Co., Ltd. Temporary office witnessed this point: here’s a backlight near corner stood a tall adult board, the board’s surface look like glass, close to the top sheet of paper to tell people that this is the amorphous silicon thin film solar cell components of the. Odd that there is no single piece of wire and components connected with the outside world, can not shine a ray of sunshine, but even the top of a small lamp lit. dell Inspiron 1720 battery Accompanied by the companies interviewed Yan One project manager explained before, a small lamp of power, is absorbing the indoor fluorescent components of energy conversion from the.
Unlimited prospects
Liu Youhai not without pride that 14% to 16.8% by 1.2, so their battery power, the actual conversion rate higher than normal silicon cells. This battery can be used for the power generation, can also be used to assist in building the energy, but also for home use, such as used in the water heater is used to lighting. By a 100-120 watt power components, ordinary people usually coupled with a board with six battery device is sufficient.
In addition, this battery can also be used in greenhouse, so that some of the specific wavelength is not power, and used for the greenhouse warming, promoting fruit and vegetable production, which is the normal silicon cells can not. Liu Youhai, currently they have established in Rugao and other places several demonstration shelf, shelf bracket model is not installed plastic membrane, but fitted with amorphous silicon thin film solar cell module. Because there is no sun can still generate electricity, so cold when the growth rate of fruits and vegetables much faster than the other sheds.
Liuyou Hai said it was optimistic about the prospects of this vast, combined with favorable investment environment of Suzhou, so the total investment of 300 million US dollars, covers an area of 253 acres of foreign-funded projects will Suzhou Foundation, a project expected to put into operation next year . In addition to construction of thin film photovoltaic control group of production bases and equipment manufacturing base, there will also set up three R & D centers, namely 30 000 square meters of advanced technology research and development center, 15,000 square meters of high agricultural experiment center and 15,000 square meters of construction integration and development centers.
New Energy and Industrial Exhibition grand
As a high-performance products, amorphous silicon thin film solar cells of course, is to lead the development of a new energy industry, beach-goers, but by no means the only beach-goers.
To park, for example, there have been aimed at the nano-optical new energy to the industry. Nano-optical semiconductor lighting and new energy is the main direction of solar photovoltaic cells, to general lighting, large screen LCD backlight modules and LED battery equipment as the breakthrough independent film.
And Universal Photovoltaic Energy (Suzhou) Co., Ltd. the same day in the park foundation’s up bright electronic items, is one example. The company by the Taiwan subsidiary of BenQ Group Lunda Electronics Co., Ltd. invested a total investment of approximately USD 500 million yuan. 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 and LED lighting applications. After the completion of up to bright electronic LED industry will be the only film from the upstream extension, middle chips, packaged applications, the downstream one-stop production company, formed in the mainland’s largest LED industry base.
Lou turnip settled on poly-can Optical Technology (Suzhou) Co., Ltd., is one example. The company consists of Xin Gu Optoelectronics Co., Ltd. in April 8, 2010 funded the establishment, mainly engaged in high-power semiconductor lighting (LED) extension and the design of industrialization. Companies registered capital of 250 million yuan, total investment of 750 million yuan.
