As the global demand for renewable, clean and safe energy demand rising, film and other new technology, innovation and adult (30.70,0.53,1.76%), the gradual reduction of the various kinds of thin-film battery is becoming the world’s new type of solar cell research focus and hot spots, and more and more widely applied in various fields, many companies in China have joined to the thin-film battery industry.
2008, Hangzhou Blue Xingxincailiao Technology Co., Ltd., Weihai Blue Star Glass Co., Ltd. and Zhejiang University jointly developed a transparent conductive film of float glass production line technology, is currently the project has entered the pilot phase. The end of this year, float-line transparent conductive film Weihai Blue Star Glass will be produced in batches.
To fill the gaps
At present solar cells are already widely used in communications, transportation, consumer products and other fields, photovoltaic power generation to include not only the country’s research plan, and included in the national electric power construction program, but also in a number of major projects has been applied. But the short term, China’s silicon solar cell industry and end markets can alleviate the dual dependence. Polysilicon and monocrystalline silicon ibm thinkpad t43p battery,ibm thinkpad t60 battery and silicon raw materials more than 90% shall be imported from abroad, while over 90% of the end product has to be exported abroad.
In 2008, swept the global financial crisis also spread to China’s solar cell industry, polysilicon prices have fallen dramatically to a historic low, the original “blue skies” of the solar cell industry, all of a sudden, “cloudy.” “Crystalline silicon is expensive and also easily affected by international markets, price volatility; while amorphous silicon thin-film solar cells because the manufacture of raw material prices are low, less susceptible to market impact, and as thin film technology advances, gradually being optimistic.” Liu Bo, general manager of Hangzhou Blue Star said.
However, in our country, the float glass line transparent conductive film development, production, or a blank, for the amorphous silicon thin-film solar cells, transparent conductive film glass entirely dependent on imports. “Our production of amorphous silicon thin film solar cells, through the acquisition of foreign production equipment and basic materials to carry out. Although the amorphous silicon thin film solar cell demand is rapidly expanding, industry expansion has brought high profits to the enterprise; but in the long run Once on the company size, industry to industry the ibm thinkpad t60p battery,ibm thinkpad r60 battery profits of the inevitable bottleneck in the transfer of a key chain. producers of products if there is no master key technologies, its profit margin is necessarily limited and can not drive the industry forward. “Liu Jun-bo lay bare our amorphous silicon thin-film solar cell industry is facing problems.
It is understood that the international community has a float glass production line technology, transparent conductive film, only two companies in Japan and the United States, “Blue Star is now finally broken the two companies of foreign monopoly in China, becoming only have a float-line transparent conductive membrane of glass production technology businesses. to the end of the year, we will be in Weihai Blue Star for mass production. “Liu Jun-bo said proudly.
Low-cost, high value-added
“Unable to self-developed transparent conductive film glass float line, China’s amorphous silicon solar cell production and promotion is bound to be limited.” Hangzhou Blue Star developed a transparent conductive film glass float line, not only broke the monopoly of foreign enterprises, let amorphous silicon thin-film ibm thinkpad r60e battery,ibm fru 92p1141 battery manufacturers and the glass industry to see a broad prospect.
Compared with the crystalline silicon solar cells, amorphous silicon thin-film solar cells of the most important advantage is cost advantage. As a basis for a transparent conductive glass material per square meter, the import price is 130 yuan more than the cost of crystalline silicon solar cells is much lower and the Hangzhou Blue Star developed transparent conductive film prices are expected to import even lower than 20% -30%. Liu Jun-bo seen that the reasons for this: “We not only developed a float-line production of transparent conductive film glass technology and manufacturing equipment is also independent research and development. Compared with foreign equipment, inputs should be reduced by 50% of.” Compared to Import products, self-developed technology and equipment to make float glass line production of transparent conductive films greatly reduce the cost, amorphous silicon thin-film solar cell manufacturer in the basic material of the cost will be greatly reduced.
In addition, Liu Bo has also revealed that because the float glass line is not transparent conductive film of silicon ibm thinkpad r32 battery,ibm thinkpad r40 battery material price restrictions, float glass production line in the heat of the glass substrate into the layers of thin film deposition, materials are cheaper, but the life of products can be to reach more than 10 years, can mass production and promotion.
While in the pilot stage, but there have been numerous glass manufacturers set their sights Hangzhou Blue Star’s float glass technology, transparent conductive film online. If the glass industry can be involved, certainly added a new economic growth point. “China’s big market space, transparent conductive film glass is a high-value-added products to our domestic glass industry that it could open up a new area of development.” Liu Jun-bo told “Zheshang” reporter, as a transparent conductive film glass production process the complexity of the float glass production line with high requirements, and therefore the ibm thinkpad t42 battery,ibm laptop battery glass manufacturers put forward higher requirements, but the production of transparent conductive film glass generate profits several times higher than the ordinary glass. “
Large-scale production can be
Compared with the crystalline silicon, transparent conductive film of glass can produce a large area very obvious advantages, it has become increasingly amorphous silicon thin-film solar cells favored by the market, one of the important reasons.
“Transparent conductive film glass, there is an advantage that it can be large-scale production.” Liu Jun-bo introduced, transparent conductive film glass is a glass substrate, the largest production area of more than 5 square meters, is monocrystalline silicon and polycrystalline silicon solar cell area several times. This large-size glass substrates for thin-film solar cells to toshiba pa3178u-1brs battery,toshiba pa3191u-1brs battery market, it will greatly speed up the building-integrated photovoltaic roof grid photovoltaic power plants and other power generation systems, as well as the promotion and popularization.
Amorphous silicon thin-film building-integrated photovoltaic solar cells is an important application, which combines solar power and function of the external walls of buildings, both power generation, but also reduce carbon dioxide emissions, which is a new trend. However, to improve efficiency, reduce costs, expand the scale is still developing, producing solar cells subject. “Although the transparent conductive film glass area, but applied to photoelectric conversion efficiency of solar cells is relatively low, only 6% -7%, so be applied in large power stations, long way to go.” Liu Jun-bo said that in future will also improve the toshiba pa3191u-2brs battery,toshiba pa3191u-3brs battery,toshiba laptop battery photoelectric conversion efficiency, and continuously carry out exploration.
