LDK Solar Co., Ltd., through its wholly owned subsidiary, Jiangxi LDK Solar Hi-Tech Co., Ltd., engages in the manufacture, processing, and sale of multicrystalline silicon wafers. Solar wafers are the principal raw material used to produce solar cells, which are devices capable of converting sunlight into electricity.
The company sells multicrystalline wafers to manufacturers of photovoltaic products, including solar cells and solar modules. It produces and sells multicrystalline solar wafers between 180 and 240 microns in thickness. In addition, the company provides wafer processing services to monocrystalline and multicrystalline solar cell and module manufacturers. The company also sells polysilicon materials, which include ingots and polysilicon scraps. The company, as of March 31, 2007, had an annual multicrystalline wafer production capacity of approximately 215 megawatts (MW).
The company manufactures and sells multicrystalline solar wafers. It uses a range of polysilicon feedstock in the production of multicrystalline wafers. The company produces and sells multicrystalline wafers in two principal sizes of 125 by 125 mm and 156 by 156 mm, and with thicknesses from 180 to 240 microns.
The company also provides wafer processing services to both monocrystalline and multicrystalline solar cell and module manufacturers, who provide with their own silicon materials, such as polysilicon feedstock and ingots. It processes such feedstock to produce ingots. The company then slices such ingots and ingots provided by customers into wafers to be delivered back to customers. It also sells silicon materials, which include ingots and polysilicon scrops.
The company sources its polysilicon feedstock from both domestic and international sources, including: semiconductor materials trading companies, such as Komex Electronic Materials Inc.; Kunical International Group Ltd.; and Prime GLP Inc.; solar cell and module makers, such as Canadian Solar, Inc. (CSI) and Q-Cells AG (Q-Cells); and solar-grade virgin polysilicon manufacturers, such as MEMC Electronic Materials, Inc. and Wacker Chemie AG.
The company’s customers, in the photovoltaic cell and module sector, include BP Solar; China Sunergy Co., Ltd.; Chinalight Solar Co., Ltd.; CSI; E-Ton; GE Energy; Mosel Vitelic; Motech; Q-Cells; Solarfun; Solartech Energy; Solland Solar Energy B.V.; and Suntech Power Holdings Co., Ltd.
The company competes with international players such as BP Solar, Deutsche Solar, Ersol Solar Energy AG, Evergreen Solar, Green Energy, JFE Steel Corporation, Kyocera Corporation, M.SETEK Co. Ltd., PV Crystalox Solar AG, Renewable Energy Corporation ASA and MEMC. It also competes with players in China such as Jinggong P-D, Shunda and Tianwei Yingli.
LDK Solar Co., Ltd. was founded in 2005.
