Import A Grade Polysilicon Wafer — Buy in Bulk from Supplier in China

This listing covers a P-type polysilicon wafer produced via diamond wire cutting, with a resistivity range of 1 to 3 ohm-cm and a minority carrier lifetime exceeding 2 seconds. The wafer dimensions are tightly controlled, with a hem width of 157.00 to 157.25 mm and a thickness of 200 ± 20 micrometers. Transfer efficiency is specified at over 18.8%, making it suitable for high-efficiency photovoltaic applications.

The material is derived from semi-melting processed polycrystalline silicon blocks, which share the same P-type resistivity and minority carrier lifetime specifications. Typical industry standards for such wafers include a surface reflectivity of less than 15% and a bow/warp tolerance under 0.3 mm, though these values should be confirmed with the supplier for this specific batch. The diamond wire cutting process ensures a smooth surface finish, which is critical for downstream cell fabrication.

These wafers are primarily used in the manufacturing of solar cells for photovoltaic modules, where high transfer efficiency and consistent electrical properties are essential. Buyers typically include solar panel manufacturers and research institutions focused on renewable energy technologies. Trade terms such as MOQ, packaging, and incoterms are not specified in the listing and should be clarified directly with Henan Hengxing PC Steel Product Co., Ltd.

Henan Hengxing PC Steel Product Co., Ltd is based in Zhengzhou, Henan Province, China, with its registered address at No.299, Jinshui Road. The company operates within the harbor trust tier, indicating a baseline level of verification for its business operations. While the response rate and average response time are currently listed as zero, this may reflect recent activity or data updates rather than a lack of engagement.

The supplier specializes in high-efficiency polycrystalline silicon products, including both blocks and wafers. Its focus on P-type materials with specified resistivity and minority carrier lifetimes suggests a technical orientation toward photovoltaic applications. No additional details about certifications, production capacity, or client base are provided in the available data, so buyers should request this information directly.
