(1) Overview of the development of photovoltaic industry at home and abroad
From the perspective of the needs of resources, environment and social development, the development and utilization of new energy and renewable resources is an inevitable trend. Solar photovoltaic power generation will occupy an important position in the world's energy consumption, not only will replace some of the conventional energy, but will also gradually become the main body of the world's energy supply.
Since the end of the 1990s, Europe, the United States, Japan and other countries have implemented the "sunshine plan", and introduced a number of preferential policies in the price of solar power, taxation, development funds, etc., driving the development of the entire photovoltaic industry. According to the EPIA (European Photovoltaic Industry Association) data, the cumulative global solar installed capacity reached 9,100 MWp (MW) in 2007 and reached 14,721 MWp in 2008. During 2000-2008, the cumulative installed capacity increased by nearly 10 times. The compound annual growth rate reached 33.9% (Source: “2009 Global Photovoltaic Industry Development Research Reportâ€). The global photovoltaic industry has been in a high-speed development stage in recent years.
Due to the impact of the Japanese nuclear leak, Germany and Switzerland have announced the abandonment of nuclear energy, and will vigorously develop new energy industries including photovoltaics, making the future of the photovoltaic industry brighter. China's photovoltaic power generation industry started in the 1970s and entered a period of steady development in the mid-1990s. Under the "Guangming Project" pilot project, "power transmission to the township", "Golden Sun Project" and other projects and the global photovoltaic market, China's photovoltaic industry has entered a stage of rapid development. According to the Medium and Long-term Development Plan for Renewable Energy, by 2020, China will strive to achieve a solar power installed capacity of 1.8GWp, which will reach 600GWp by 2050.
(2) crystalline silicon solar cells occupy the dominant position of solar cells
The photovoltaic industry chain is composed of ultra-pure silicon materials, silicon ingot/wafer production, solar cell manufacturing, photovoltaic module packaging and photovoltaic power generation system integration. Solar cells are one of the core components of photovoltaic power generation systems. The rapid development of the photovoltaic industry has driven the growth in demand for solar cells. In 2004, China's solar cell production capacity was less than 100MWp. By 2009, the national solar cell production reached 4,011MWp, and in 2010 it reached 8,000MWp, an increase of 80 times in 6 years. At present, China has surpassed Europe and Japan to become the world's major solar cell producers. (Source: “2010-2015 China Solar Cell Industry Investment Analysis and Forecast Reportâ€)
At present, solar cells are mainly divided into three types: crystalline silicon solar cells (including polycrystalline silicon cells and monocrystalline silicon cells), thin film cells and dye-sensitized nanocrystalline thin film solar cells (not yet commercialized in research and development). Since crystalline silicon solar cells have the advantages of high conversion efficiency, stable performance, and high degree of commercialization, they have always occupied the leading position of solar cells. In 2010, crystalline silicon solar cell production accounted for more than 90% of the world's total solar cell production.
(3) The strong demand for crystalline silicon solar cells has driven the development of solar crystal silicon cutting fluid market
The rapidly developing solar cell industry has created huge demand for its main raw material silicon wafers, which indirectly creates a broad market space for the solar crystal silicon cutting fluid industry, which is a necessity in the production process of silicon wafers. At present, China has become the world's most important production base for polysilicon chipping and solar cell assembly. As the capacity of solar wafers continues to expand, the demand for solar crystalline silicon cutting fluids continues to grow. It is expected that the domestic demand for solar crystalline silicon cutting fluids will reach 647,000 tons in 2014.
"2012 China Solar Wafer PEG Cutting Fluid Industry Market Research Forecast Report"
Driven by the development of silicon wafer cutting technology, the thickness of silicon wafers has been reduced from 330 microns in 2002 to the current mainstream of 220 or 200 microns. The reduction of the thickness of the silicon wafer enables the number of silicon wafers that can be cut per unit weight of the crystalline silicon material to be continuously increased, thereby increasing the cutting area and directly increasing the consumption of the crystalline silicon cutting fluid. It is expected that as the technology advances, the thickness of the silicon wafer will become smaller and smaller, and the demand for solar crystalline silicon cutting fluid will also become larger and larger.
(4) Current development of domestic solar crystal silicon industry
According to the China PV Industry Development Report released by the China Photovoltaic Industry Alliance (CPIA) and the International Semiconductor Equipment and Materials Industry Association (SEMI), the production capacity of crystalline silicon cells in China has exceeded 30GW, and the built capacity of the domestic PV industry is quite large. The corresponding demand for crystalline silicon cutting fluid is quite large.
China's solar energy enterprises are concentrated in the downstream battery and component manufacturing links with low added value in the industrial chain. The upstream crystalline silicon material is mainly monopolized by several major manufacturers in Europe, America and Japan, while the downstream photovoltaic power generation market is mainly concentrated in Europe, causing the situation of “two heads outsideâ€. At the same time, the domestic PV industry's production capacity has risen rapidly, coupled with the development of its own PV industry, and encountered international trade barriers. In the second half of 2011, it experienced difficulties such as overcapacity and price decline, which also enabled the company's cutting fluid products to maintain sustained and rapid growth. Faced with pressure.
However, throughout the year of 2011, the domestic market still maintains the demand for crystalline silicon cutting fluid. At the end of 2011, the National Energy Administration recently announced a series of renewable energy “Twelfth Five-Year Plan†targets mentioned. During the “Twelfth Five-Year Plan†period, the annual average annual installed capacity of photovoltaics will reach 3.5GW. The new installed capacity in 2012 is expected to be close. 3GW, an increase of about 300% compared to 2011.
At present, the company is actively improving the production technology of crystalline silicon cutting fluid. On the one hand, the company will improve the formulation and technology of existing cutting fluid products, reduce the cost of products, and help domestic crystalline silicon enterprises to reduce costs and improve their risk resistance, so as to continue to expand the market share of cutting fluid products. On the other hand, the company is committed to developing high-end new products, such as diamond wire silicon cutting fluid, with years of experience and leading research and development capabilities to meet the needs of upgrading and development of the crystalline silicon cutting industry. If there is a significant adverse change in the development of the crystalline silicon cutting fluid industry, the production process of the company's polyether monomer and crystalline silicon cutting fluid is similar, the main raw materials and equipment are the same, and the capacity distribution can be flexibly switched between the two products to cope with market fluctuations.
