Import 156x156mm 200um High Quality Polysilicon Wafer — Buy in Bulk from Supplier in China

This 156x156mm polycrystalline silicon wafer from Henan Hengxing is a P-type substrate produced using diamond wire cutting technology. The wafer has a nominal thickness of 200 micrometres with a tolerance of ±20 micrometres, a hem width range of 157.00 to 157.25mm, and a measured resistivity of 1 to 3 ohm-centimetres. The supplier reports a minority carrier lifetime exceeding 2 microseconds and a transfer efficiency greater than 18.8%.

Polycrystalline silicon wafers of this dimension are a standard format for terrestrial photovoltaic cell production, typically processed into multi-crystalline solar cells. The P-type doping with boron is the conventional approach for this wafer class. Diamond wire cutting is a modern technique that reduces silicon loss and surface damage compared to older slurry-based methods, which is relevant for cell yield and material cost. The stated efficiency figure of over 18.8% is within the typical performance band for commercial multi-crystalline cells.

These wafers are purchased by solar cell manufacturers and module assemblers for integration into photovoltaic panels. Buyers in this sector source based on wafer dimension, thickness uniformity, resistivity range, and minority carrier lifetime, as these directly influence final cell conversion efficiency. Henan Hengxing operates from Zhengzhou, Henan province, and the specific trade terms such as minimum order quantity, packaging configuration, and lead time should be confirmed directly with the supplier, as they are not detailed in the listing.

Henan Hengxing PC Steel Product Co., Ltd is based at No.299, Jinshui Road, Zhengzhou, Henan, China. The company was established in 1995 and has over two decades of operational history in wire transformation and coating industries. Its core product lines include galvanized steel wire, strand, PC steel wire strand, steel cord for radial tyres, and hydraulic hose, alongside its polycrystalline silicon wafer production. The firm was listed on the Shenzhen A-stock market in 2007.

The supplier states it operates an independent R&D centre and holds certifications including ISO, SGS, and BV. The listing describes it as the largest manufacturer of galvanized steel wire and strand in China, and a major producer of steel cord for radial tyres. However, the listing does not provide specific details on its silicon wafer production capacity, dedicated wafer manufacturing lines, or the volume of its polysilicon business relative to its steel operations. The supplier's current response rate on this platform is listed as 0.00, so buyers should use direct contact methods to establish communication.
