High-purity metallurgical grade silicon (UMG-Si) solar cell products into the market

CANADIAN SOLAR components that UMG e-Modules officially off the assembly line

In mid-June, CANADIAN SOLAR in Munich, Germany, the Intersolar exhibition, launched by a grand refined into metallurgical silicon solar grade silicon production of new components - and named for the e-Module. So that it will become the world's first successful metallurgical silicon (UMG-Si) solar grade silicon refined into commercial production companies.

The advantages of e-Modules

1. Cost advantages, UMG silicon (high-purity metallurgical grade silicon) is a selective purified silicon raw materials, as from the "Silicon ore - metallurgical silicon - High-purity silicon - monocrystalline silicon or polysilicon - silicon - the battery - Group Pieces - applications, "the battery industry chain in the third procedure, the high-grade metallurgical silicon processes to reduce the purification was not easy to introduce environmental problems caused by the chemicals, and reduce the cost of many. The current production of high-grade metallurgical silicon in the purchase price of approximately 60-70 dollars / KG, and the traditional polysilicon purchase price of up to 500 U.S. dollars / KG.

2. More environmental protection, production processes from the point of view, UMG silicon materials (high-purity metallurgical grade silicon) battery cleaner, producing less loss of energy in the process. Silicon, the basic pattern and its natural hybrid forms are harmless. It can be said, UMG silicon materials (high-purity metallurgical grade silicon) is the most economical on the market the most reliable of the most environmentally friendly photovoltaic material.

3. Battery the most important parameters - photoelectric conversion efficiency and the decay rate, UMG silicon materials (high-purity metallurgical grade silicon) for the conversion efficiency of the current 13-15 percent, and conversion efficiency than the traditional polysilicon little gap , And the cost savings as much as several times. Optoelectronic thin film solar cell conversion efficiency generally lower than 10%. In low-efficiency solar cells and thin film of crystalline silicon cells efficiently between, people naturally look forward to the third better choice.
