The core in the investment of 200 million yuan to build silicon solar cell production line chip

Has been repeated use of waste chip integrated circuit more than and 10, should be "squeezed" again, for the regeneration of high standard solar cell chip - a fill in the blank of silicon solar cell chip production line is SMIC IC company construction, is expected to go into operation early next year.

SMIC integrated circuit Co., Ltd. is currently the largest integrated circuit chip manufacturer, the company in the semiconductor chip manufacturing process, will be accompanied by the production of chips used to test the performance of the chip. The waste itself has been repeated by more than and 10 times, the wafer reused to no test chip value, manufacturers usually buried its crack. SMIC ", will be saved, One loves what is his own." these waste wafer carefully turning waste into treasure, production of the international market popular current silicon solar cell chip.

SMIC solar project manager Su Xiaoping said, the integrated circuit chip production requirements test chip performance, even if the wafer waste material, after the performance is also much higher than that of the general requirements of the silicon solar cell chip. According to preliminary estimates, the production of silicon solar cells with this method can reduce the cost of production, but also to achieve the goal of 17% photoelectric conversion rate of the world-class quality standards.

It is a mature approach to develop renewable silicon solar cell chips with discarded chips. American Astropower company uses this method to produce 32 megawatts of solar silicon solar cells every year. At present, there is no domestic enterprises in this way large-scale renewable silicon solar cell chip. The solar photovoltaic battery industry is listed as "11th Five-Year 11th Five-Year < >" industry focus on planning, but most enterprises currently only have silicon solar battery components production capacity, silicon solar battery chip production is almost blank.

It is reported that officially put into operation in the first quarter of next year after the core in silicon solar cell chip production project investment 200 million yuan, the initial formation of a 10 megawatt production scale, within 5 years will invest 1 billion yuan, formed a production capacity of 100 megawatts. SMIC hopes to use the company's comprehensive advantages, and gradually form a low-cost, with independent intellectual property rights of intellectual property rights and international competitiveness of the solar cell industry chain.
