At present photovoltaic cells from the functional material thickness of the body Laptop Battery can be divided into two kinds of photovoltaic cells and thin-film batteries. The material of the battery can be divided into monocrystalline silicon cells and batteries, in addition to a small amount of flake silicon photovoltaic cells. Thin-film amorphous silicon thin film photovoltaic cells include cells, copper indium selenide (CIS) solar cells, solar cells cadmium antimonide, gallium arsenide solar cells and so on. In the cutting-edge research phase also includes the nano-silicon thin-film solar photovoltaic cells, etc., in the future will have broad application prospects.
In recent years, the development of thin-film battery industry
The increasing calls for environmental protection, traditional energy emergency situation, the solar photovoltaic industry in recent years, rapid development of crystalline silicon cell production from 2001 to 338.1MWp development in 2004 1136MWp, that by 2007 had reached 3650MWp; film Battery 2004 annual output of 36MWp, 2004 had increased to 65MWp, but by 2007 increased to 350MWp, accounting for nearly 10% of total production. According to available data, in 2008 will reach 6100WMp crystalline silicon cells around thin-film batteries to 1100WMp. From a range of data we can see that the development of solar cell industry has entered the fast lane, while the thin-film battery industry evolves, in recent years, shows potential for Pavilion dv2000(hp dv2000 battery) development.
As we all know, crystal silicon energy-intensive production process, manufacturing costs are high, prompting the high cost of power generation. Compared to crystalline silicon solar cells, thin-film battery production process is simple, are not subject to restrictions on silicone materials, manufacturing costs are lower, thus resulting in reduced cost of power generation. Thin-film solar cell manufacturers in recent years, the rapid increase in the beginning, the original only in Harbin Crolla, Shenzhen Yu-Kang 1MW single-junction a-Si cell production line, after the increase in Fujian Jun Shi energy, Tianjin energy, such as已建和在建of Bengbu Pollock More than 20 thin-film battery manufacturer, size from a few MW to tens of megawatts, the product sizes up to several square meters square meters, and by a a-Si/a-Si laminated batteries and stable efficiency of up to 5% -6%, and enter the power-based application stage, there are a number of enterprises plan to scale up to hundreds of megawatts. Originally involved in the production of crystalline silicon solar cell manufacturers have also started to increase thin film product line, such as representatives of the industry companies involved in silicon-based Suntech, have begun to thin film solar cell production. From this point of view, thin-film solar cell industry vitality dejected. The following, from the aspects enumerated in the past two years the development of the domestic thin-film PP2200 battery industry overview.
In February 2008, Shandong Vosges Photovoltaic Technology Co., Ltd. to introduce German Johanna Solar Technology GmbH (referred to as JST) technical construction CIGSSe (copper indium gallium sulfur compounds, selenium) thin film solar cell R & D and production projects in the city Shenbei New Gaomi Vosges official started the foundation, marks the beginning of the high-end research and development into solar cell production technology. The project total investment 60 million yuan, the construction scale of 240MW. Of which 1.86 billion first phase of project investment, the construction scale of 60MW, is expected to put into the third quarter of 2009.
November 2008, Nankai University and the Fujian-Jun stone Energy Limited set up a joint laboratory on silicon thin-film solar parks inaugurated in Tianjin, Ling Ao creativity. School enterprises to establish strategic cooperative partnership between the two sides will work together to research and development of thin-film solar cell industry. "Tenth Five-Year" period, the Task Force amorphous silicon / microcrystalline silicon stacked cell research has reached pavillion zx5000(hp zx5000 battery) the international advanced level, developed a series of thin-film cell manufacturing key equipment and the necessary test systems, has established the only international advanced level, silicon thin film solar cell research lines.
In January 2009, the Guangdong Provincial Government and China National Building Material Group Corporation provides solar Kam strategic cooperation framework agreement, China National Building Material Group Corporation will invest 3.0 billion to build park in Sanshui, Foshan, Guangdong solar energy industry base. Under the agreement, China National Building Material Group Corporation will invest in capital construction technology and equipment in Guangdong Zhongnan Optical Co., Ltd., Guangdong, China and South Africa photovoltaic technology (equipment) R & D Center, Guangdong China and South Africa Solar Energy Co., Ltd. 3 project to establish set photovoltaic technology (equipment) R & D , photoelectric technology and equipment manufacturing and thin-film solar module production base for solar energy industry.
In February 2009, from the securities company data show that in late January has been, A share market the concept of thin-film batteries have a number of stocks, such as Jin Jing technology, Vosges stake had good performance, a lot of stocks and a continuous daily limit. For this forecast, there are investors that the thin-film battery Presario V2000(compaq v2000 battery) technology, the threshold is very high, the conversion rate is not an effective breakthrough in production will cause a lot of waste, the future competitiveness of their products will not optimistic.
ZF's current conversion efficiency of thin-film battery has reached 16% in 2008 has been 3.8Mw production in 2009 is expected to form a 25Mw capacity. ZF CIGSSe method employed by the risk of thin-film battery technology has become lost, technology providers Johanna was in November 2008 began production, the current products have external sales. The next three years, the underwriting to the German thin-film battery joint venture parties will effectively reduce the company's early stage of thin-film battery market risk, in order to lay the foundation to cultivate their own brands. The company's thin-film batteries have already been proposed in place of project funds in 2009 and 2010 will proceed as planned the formation of 30Mw and 60Mw capacity.
Thin-film battery technology research and industry status
Compared with the international advanced level, our Presario M2000(compaq m2000 battery) study of thin-film batteries there is a certain gap, but is gradually narrowing. China in a variety of thin-film solar cell research, has a very good basis for further study and development potential. "Tenth Five-Year" period, "973 Plan" and "863 Program", respectively, the silicon-based thin-film solar cells and dye-sensitized solar cells, as well as cadmium telluride and copper indium selenide thin-film solar cells solar cells as a major project of the project and the research, and in the "Eleventh Five-Year" period to continue the project. In the 863 key projects with the support of Sichuan University and Nankai University are 300 kilowatts respectively cadmium telluride and copper indium selenide solar cells in solar cell R & D pilot production line; in 973 projects, supported by the plasma of the Chinese Academy of Sciences and Nankai University in are separate dye-sensitized solar cell, and a new high-performance Pavilion ZE2000(hp ze2000 battery) silicon thin-film solar cell industry, technology research work
