Suzhou, April. 11th, 2018 /PRNewswire/ — GCL-Poly Energy Holdings Limited (HK: 3800), a subsidiary of the world’s leading clean energy conglomerate GCL, issued an important announcement on the evening of April 10 that it has entered into an agreement with Qujing municipal government, Yunnan Province, China to invest 9 billion yuan to build a monocrystalline silicon project in Qujing’s Economic and Technological Development Zone with a designed capacity of 20 GW. According to the announcement, the JV will use the revolutionary CCZ continuous Czochralski monosilicon technology at the new facility.
CCZ is the next-generation high-efficiency monocrystalline technology. It adopts a special Czochralski crystal growing furnace to realize crystal pulling while feeding and melting. 8-10 rods can be pulled within the life cycle of a crucible. At present, the mainstream technology is the RCZ (recharged Czochralski) technology. Compared with RCZ, the crystal rods produced by CCZ are of better quality, and the resistivity is more uniform and narrower in distribution, which therefore are more suitable for P-type PERC and N-type batteries.
In April 2017, GCL-Poly announced that it had completed the acquisition of SunEdison’s fifth-generation CCZ technology, FBR silane fluidized bed technology and assets. “As FBR’s high-quality granular silicon can be used as the best material for CCZ, the two technologies are complementary and a synergy effect of 1+1>2 can be achieved”said Mr. Wan Yuepeng, CTO of GCL-Poly. This high-tech barrier and high-value-added technology will greatly enhance the company’s core competitiveness.
GCL-Poly has, in the past year, further improved CCZ’s cost efficiency and product quality through domestic equipment and supply chain development, and process optimization. By the time of new fab commissioning, GCL-Poly will become the only company in the world realizing the industrialization of CCZ technology and will take the monocrystalline silicon wafer industry to the next technology level.
GCL-Poly Energy Holdings Limited (HK: 3800) is part of the GOLDEN CONCORD Group (GCL). GCL-Poly is the world’s largest polysilicon and wafer supplier as well as one of the top green energy and solar power investors and operators.
