Polysilicon has changed dramatically in the past two years, from 3 million to 400,000 per ton, and its price is like riding a roller coaster. From another perspective, this price is also a rational return. What is polysilicon? Polycrystalline silicon is a form of elemental silicon. When the molten elemental silicon under supercooling solidification, the silicon atoms are arranged in a diamond lattice form many crystal nuclei, these nuclei grow into such different crystal orientation grains, these grains together, crystallizes into Polysilicon. Polycrystalline silicon can be used as a raw material for drawing single crystal silicon , and the difference between polycrystalline silicon and single crystal silicon is mainly manifested in physical properties. For example, in terms of anisotropy of mechanical properties, optical properties, and thermal properties, it is much less pronounced than monocrystalline silicon; in terms of electrical properties, polycrystalline silicon crystals are much less conductive than monocrystalline silicon, and even have little conductivity. In terms of chemical activity, the difference between the two is extremely small. Polycrystalline silicon and single crystal silicon can be distinguished from each other in appearance, but the true identification must be determined by analysis of the crystal plane orientation, conductivity type, and resistivity. Polycrystalline silicon is a direct raw material for the production of single crystal silicon, and is an electronic information basic material for semiconductor devices such as artificial intelligence, automatic control, information processing, and photoelectric conversion. Known as "the cornerstone of the microelectronics building." Monocrystalline silicon and polycrystalline silicon also play a huge role in solar energy utilization. Although at present, to make solar power have a large market and be accepted by the vast number of consumers, it is necessary to improve the photoelectric conversion efficiency of solar cells and reduce production costs. From the current development process of international solar cells, it can be seen that the development trend is monocrystalline silicon, polycrystalline silicon, ribbon silicon, thin film materials (including microcrystalline silicon-based films, compound-based films and dye films).         Polysilicon, crazy “2008” Before the financial crisis broke out in 2008, under the dual influence of strong downstream demand in the photovoltaic industry chain and slow release of new upstream production capacity, the spot price of polysilicon exceeded 280 USD/kg in the third quarter of 2006, and the fourth quarter. After breaking through 300 US dollars/kg and breaking through 300-330 US dollars/kg in the first half of 2007, the first quarter of 2007 exceeded the price of 340 US dollars for the first time. The transaction price in the first quarter of the fourth quarter soared to 360-370 US dollars. By the beginning of 2008, the price broke through. The $400/kg mark. In April 2008, the polysilicon spot market reported a transaction price of 500 to 510 US dollars per kilogram, a new high, and the spot price rose again. The reason is that the US polysilicon manufacturer M EMC , which accounts for 13% of the global total capacity, has reduced its shipments by 20% in the first quarter, significantly reducing the supply of supply contracts to customers in the spot market, coupled with strong terminal demand. The supply situation of polysilicon spot market is more tight, and the rapid depreciation of the US dollar has also played a certain role in boosting this increase. The relevant analysis believes that: 1. This price is the spot price sold by the middleman, not the spot sales price of the polysilicon manufacturer. The sales price of up to 500 US dollars / kg is only about 20 tons, which can not represent the whole spot market situation of polysilicon. At that time, the price of domestic polysilicon manufacturers increased slightly, but the tax price was basically less than 400 US dollars / kg.

2. In addition to insufficient supply of polysilicon, the terminal photovoltaic market is another important reason for the rising spot price of polysilicon since 2008. Spain's first phase of photovoltaic subsidies ended in September of that year, the relevant manufacturers stepped up the stocking caused the relative supply of the entire industry chain is relatively tight, photovoltaic cell manufacturers will also buy some high-priced spot silicon materials to prevent default, strong terminal demand and upstream supply shortage together lead to polysilicon Spot prices have risen again. 3. Based on the rapid amplification of polysilicon production and the comparative analysis of supply and demand, it was estimated that the expected price of polysilicon spot market in 2009 dropped to an annual average price of around US$250 and the long-term order became an important component of domestic polysilicon manufacturers.

4. Polysilicon prices have been the hottest topic in the industry, and the rapid growth in demand for solar cells has caused prices to rise to $500/kg. Some reports show that the growth rate of the solar cell industry in the past 10 years is 30% to 40%.         The expansion of the production of polysilicon prices plunged the financial crisis, the semiconductor recession coupled with the rapid demand for solar energy, the past smashed the price of polysilicon mad, from the price of 400 yuan per kilogram of the old-fashioned factory grade polysilicon spot price In December 2008, it plunged to 150-175 US dollars per kilogram, setting a new low in the past three years. The price of the single-season was not the same as that of the old-fashioned factory. The price per kilogram was more than one hundred dollars. Amplifying the sluggish semiconductor industry, polysilicon moved to the solar photovoltaic industry, but it has encountered the traditional low-temperature demand of solar photovoltaics and the change of policy subsidies and the financial storm. The polysilicon that has always been "black gold" is also the same as international oil. Plunge. In late December 2008, the price of polysilicon produced by the old factory in the spot market has dropped to 150-175 US dollars per kilogram. Compared with the October 2008 price, it can still maintain 400 US dollars per kilogram. The price in the first quarter has dropped by 50%. Above, if the spot price of polysilicon broke through 200 US dollars in March 2006, the price also hit a new low price in the spot market in the past 3 years. The spot price of polysilicon, which is stable in quality, is directly eroded, which also greatly affects the price of raw materials produced by other new entrants. Instead of the old-fashioned factory polysilicon, it is impossible to gain trust due to quality stability, and the market is out of stock, the value is plummeting. More serious, the spot price also fell below 100 US dollars per kilogram, all kinds of low-level quotations have come out, some from the new entrants low-cost sales are mainly used for financing, and partly from serious inventory pressure. The old polysilicon factory is mainly American Hemlock, Norwegian REC, German Wacker, US MEMC, etc. The supply rate is over 80%, and the quality stability is affirmed. “Happiness and Worry” of PV Enterprises In 2007, the global solar cell production was 3,400 MW, and China’s output was nearly one-third, which was 1,100 MW, but mainly based on exports, and the export market was concentrated in Europe. In 2008, driven by the strong market demand in Spain, global demand will reach 5,000 megawatts, a year-on-year growth rate of 48%. As a result, many solar cell manufacturers have delayed delivery because polysilicon is not in place. In 2007, the profit margin of polysilicon enterprises was about 63%. In the entire industrial chain, the profit share of this link reached 19%. For example, Wacker Chemical, the second largest polysilicon manufacturer in the world, still benefited from the continued high demand for polysilicon in the third quarter. The business unit's total sales were 238.9 million euros, a year-on-year increase of 90%. At the same time, the expansion of the world's mainstream polysilicon manufacturers is also quite amazing. The expansion plans of Hemlock and MEMC in 2009 were 12,800 tons and 7,700 tons respectively, WACKER was 12,000 tons, and REC's expansion plan was 9,200 tons. Due to the large expansion of polysilicon and the increased risk in the overseas market, the downturn in the terminal solar market has brought about a sharp drop in polysilicon prices. The domestic polysilicon scale production plan is also quite large. According to statistics, in 2008, more than 60 polysilicon projects were built, under construction and planned by domestic enterprises. In 2009, there were Xuzhou Zhongneng, Luoyang Zhongwa and Xinguang Silicon in the production of polysilicon exceeding 1,000 tons. The price of polysilicon plummeted, making domestic PV companies “mixed and mixed”: on the one hand, production costs have been greatly reduced, but there is still a weakening of market demand, which has dragged down corporate performance.
