” Polycrystalline silicon technical standard finish already, deliver the related departments to to examine and approve. ” On January 26, Chinese regenerated energy society’s Vice President Zhao YuWen represents the staff reporter. This means, the first national standard of Chinese polycrystalline silicon trade, will issue soon.

However, one participates in making the canonial personage of the above-mentioned technology to show, this standard does not have coercive power, ” But establish a reference standard for our country’s relevant industry, but this means, the relevant industry will act basing on this standard later, for example purchase and competitive bidding “.

This personage reveals, the above-mentioned standard will divide into two big classes. First, apply to polycrystalline silicon (energy of the sun polycrystalline silicon) of the solar energy,Another polycrystalline silicon (the intersection of electronic stage and polycrystalline silicon) to apply to integrated circuit,There are about 20 concrete indexes. Among them, the most crucial one is the purity index, energy of the sun polycrystalline silicon demands not to be lower than 7 times 9 (namely 99.99999%),Polycrystalline silicon of electronic stage is not lower than 11 times 9.

At present, the products of a lot of domestic small-scale polycrystalline silicon enterprises only reach the level of 6 times 9, ” Productivity is under 1,000 tons, are basically all this kind of situation. The standard appears on the stage, may mean they must put into more, in order to reach the corresponding standard “.

After entering the 21st century, hold the appearance of the tide with new energy, polycrystalline silicon is regarded as the raw materials of the solar battery products, pursued by the market. Chinese the intersection of polycrystalline silicon and productivity rise to 2009 5 to 60,000 from 100 for 2004, suddenly become five most crystal silicon produce the ground before the world.

However, China has never had an intact polycrystalline silicon technical standard, in the view of above-mentioned personage, ” This is unfavorable to promotion of the quality of polycrystalline silicon products of our country “.

In his view, once establish corresponding polycrystalline silicon product standard, ” The domestic manufacturing enterprise has a reference system, the relevant trade of polycrystalline silicon will utilize this object of reference too, for example, in the bid of the domestic photovoltaic project, can do in order to require with this standard, thus promote the promotion of domestic polycrystalline silicon industry “.

And,” With the canonial introduction of polycrystalline silicon of our country, export of polycrystalline silicon products of our country, also win help. ”

This personage claims, China will also promote the canonial setting-up of international polycrystalline silicon. ” Once set up associated standard in the world, then, other countries are while opposing polycrystalline silicon products of our country are exported, must follow the corresponding international technical standard and act “.

A new study by the Silicon Valley Toxics Coalition has found that much of the solar energy industry still lacks widespread standards to make its products as environmentally safe and “green” as the renewable energy it produces.

While solar energy may be one of the fastest growing forms of energy in the country, a new study suggests the industry still has some environmental health and safety adjustments it must make to improve its products’ quality.

Of the 14 solar energy products companies surveyed, more than half said they supported mandatory take-back and recycling programs where their solar panels are sold, while 50 percent said they would consider offering recycling programs to consumers free of charge.
