Expert: Problem of industry of our country smooth hot season is both ends outer
On January 5, 2007 9:34 origin: Daily of science and technology "At present the outstanding issue of industry of bend over of our country solar energy light is both ends outer. " Du Xiangwan of assistant dean of Chinese Academy of Engineering was in a few days ago " Chinese solar energy developed strategic forum 2006 " on say, because level of science and technology is restricted, the core parts of an apparatus or appliance that our country still cannot produce property of solar energy smooth hot season independently up to now -- , tall purity polycrystalline silicon, can rely on an entrance only, make the upper reaches of industrial catenary this one is outer; And this kind of current situation brought about house of cost of industry of our country smooth hot season not to fall high again, more than 70 % use the product of solar energy to be able to export abroad only, make industrial catenary downstream this one is outer.

China but Shi Dinghuan of director of institute of second birth the sources of energy has the same feeling greatly also to this, he points out clearly in the speech, the lack of material of the silicon in industry of bend over of our country solar energy light already became the final bottleneck that restricts development of our country relevant business. "Silicon chip, batteries piece, package manufacturer is eager to rapid dilate producing can, supply chain in industry of smooth hot season however ' fall to go up greatly small ' below the case that presents pyramid to distributing, the outspread speed of silicon material of upper reaches and ingot casting, section lags behind at downstream batteries piece the outspread speed with batteries component, the upriver product of the majority relies on an entrance, development of estate of smooth to our country hot season is very adverse. Such not only raised cost, and lost the initiative that masters the market. "

Forecast according to the expert, to 2020, guang Fufa report will take solar energy the whole world generates electricity the 1 % of gross; To 2040, electricenergy production of smooth hot season will occupy the whole world to generate electricity the 21 % of gross. And the flying development that reachs its to use data as technology of current world photoelectricity, photoelectricity cost of material drops considerably, photoelectricity changeover rate rises ceaselessly, the cost that prospective solar energy generates electricity will drop substantially.
