According to statistics, China solar cell production accounted for one-third of the world, became the first in the world.
December 9, a hub of China PV industry environmental technology products--Silicon-hydrogen furnace uses charcoal/carbon thermal field, through technical appraisal in Shaanxi Province Department of science and technology organizations. The products from the space of four ultra carbon/carbon materials thermal field developed by the company, mainly used in Solar polysilicon production area, is the main material manufacturing polycrystalline silicon-hydrogen furnace.
Made up of Chinese Academy of engineering sunjinliang Evaluation Board believes that this original product manufacturing technology, product does not function, reach the international senior level, filling the vacancies at home. Through polysilicon produced enterprise using confirmed, this a products break has abroad technology monopoly, in reliability, and does not mess sexual and energy-saving consumption, indicators Shang greatly better than abroad similar products, will abroad similar products uniform 6 months using period of Foundation Shang progress to 11 months of level, implementation has will hydrogen of technology process in the of units power consumption by originally of 4 to 6-kilowatt Shi fell to 2-kilowatt Shi around of target. Polysilicon Enterprise General used "improved Siemens method" technology processing exhaust, but this a method by using of hot hydrogen of device in the of hot field material full relies on entry, grim hinder has China PV industrial of health development, and, produced solar cell process in the by produced of exhaust processing is is plagued industry of a large setbacks, in polysilicon of processing process in the, polysilicon hydrogen of furnace can to produced process in the produced of "highly toxic exhaust" all recovery then using, makes high energy, and high pollution of polysilicon produced implementation "zero pollution" and " Zero-emissions ".
