Analysis of problem of industry of our country smooth hot season and dug
From;    Author:Stand originally
As fossil the sources of energy decrease increasingly, what the environment pollutes is serious with each passing day, but second birth the sources of energy especially solar energy industry gained unprecedented development opportunity. According to the news that Solarbuzz announces, the crop of global solar battery achieved 3436MW 2007, grow 55.9% compared to the same period, and the global market of manufacturer of Chinese solar battery is had rate, criterion by 2006 20% grow 2007 35% ; One of base of property of solar energy smooth hot season with had made the whole world the mainest, manufacturer of before the whole world 10 battery of smooth hot season is medium 2008, china occupied 4, this explains industry of our country smooth hot season has vast development space adequately.
But the problem that the development of industry of our country smooth hot season faces also is quite austere, namely technology of core of polycrystalline silicon extract and market of terminal of smooth hot season all are in abroad, what domestic company is engaged in is technical content mostly what reduce relatively is medium downstream industry catenary, this affected the promotion of the core competition ability of industry of our country smooth hot season badly. At present this one state is alleviating stage by stage, accordingly we hold what accumulate ecstasy view quite to anticipate to the development of industry of our country smooth hot season.
One, the hopeful inside 3 years solves problem of unbalance of polycrystalline silicon supply and demand
From 2004 industry of global smooth hot season grows quickly up to now, the problem of unbalance of polycrystalline silicon supply and demand did not get be settlemented effectively all the time, nanjing is medium 2007 because report does not have the supplier of upriver raw material that stabilizes for a long time, times get silicon chip price mad go up suffer, 89.2% what the cost of its silicon chip had held manufacturing totle drilling cost, appeared the net loss of millions dollar, the person that because there is “ inside visit course of study,get silicon gets the statement of the world ” .
The reason of unbalance of polycrystalline silicon supply and demand basically is mastering in abroad at extract core technology in hand of 7 big firms, they are Hemlock (the United States) , Wacker (Germany) , Tokuyama (Japan) , REC (Norwegian) , MEMC(United States, Italy) , Mitsubishi (Japan, United States) with Sumitomo (Japan) , the polycrystalline silicon that offers with 7 big firms satisfies the need that industry of global smooth hot season admits at full speed, occurrence supply and demand is serious unbalance, cause silicon chip price by the 10-20 dollar 2002 / kilogram shoot up present 400 dollars / kilogram no wonder also.
At present this state appeared it seems that partial a favourable turn, on one hand 7 big firms are being produced in vigorous expansion can, they are aggregate 2008-2010 year produce can make an appointment with 55000 tons, 73000 tons, 84000 tons, considering reclaim to trash wait for environmental protection the demand is higher, we predict its 2008-2010 produces per year a quantity to be able to amount to 42000 tons, 60000 tons, 80000 tons; On the other hand domestic and international a lot of new entrant is joined, they are aggregate 2008-2010 year produce can make an appointment with 10000 tons, 20000 tons, 21000 tons. Predicting 2008-2010 year crop is 5000 tons, 10000 tons, 15000 tons.
