Domestic solar cell material filler
Purification of domestic raw material processing capacity of solar cells to achieve a major 92p1102 breakthrough. Shanghai Institute of Technical Physics, Chinese Academy of Sciences has announced that the Institute to assist local enterprises to 99.9999% quasi-scale production of high purity polysilicon, and a small amount of test output for more than 99.999999% purity silicon body, after the two purity grades were still domestic blank.
Manufacture of solar cells to be used for more than 99.9999% purity polysilicon material, usually in “N”, said after the decimal point “9″, N the greater the higher the purity. For a long time, 4N to 10N polysilicon production technology in China is still empty, this key raw materials Canon NB-5H,, almost all rely on imports. Sanken co-production of high-purity silicon, solar cell manufacturing all through the trial process has been to meet the current commercial solar cell technology index after import substitution can greatly reduce production costs, speed up the popularization of solar cells families.
