Chinese polysilicon supplier Tongwei Solar has signed an agreement with Leshan City, Sichuan Province to establish a 200,000 metric tonne (MT) polysilicon manufacturing plant.
The PV industry “must remain vigilant” across its supply chain in meeting global human rights standards, trade association SolarPower Europe has said in a new sustainability report.
Major China-based polysilicon producer Xinte Energy is to expand polysilicon production by 20,000MT to meet ongoing demand from its plant in Xinjiang province, despite recently announcing plans to build a planned 200,000MT plant near the city of Baotou, Inner Mongolia.
Having topped RMB1.9/Watt (US$0.29/W) in early 2020 before falling to RMB1.4/Watt (US$0.21/W), PV module prices in China have been on a rollercoaster of late. PV Tech's Carrie Xiao has the latest on module pricing from China.
In the full-year 2021, Daqo said it expects to produce approximately 80,000 to 81,000MT of polysilicon, compared to 77,288MT in 2020. The slight increase will be due to debottlenecking activities.
GCL-Poly said in a financial filing that its FBR produced silicon had met a number of quality standards in-line with the Siemens process, while in certain parameters outperforming the dense silicon materials.
Small polysilicon producer REC Solar Norway has claimed a carbon footprint of 11.2kg CO2-eq per kg silicon, which was verified by EPD Norway and published Environmental Product Declarations (EPDs) for solar grade silicon and for multicrystalline silicon blocks made by REC.
Leading monocrystalline wafer producer LONGi Green Energy has signed a three-year high-purity polysilicon supply deal from OCI Malaysia, while securing 46GW of PV glass from China's Flat Glass Co.
Major ‘Solar Module Super League’ (SMSL) member JinkoSolar has extended its supply chain cooperation with major polysilicon and merchant solar cell manufacturer Tongwei Group, with Tongwei gaining extra gigawatts of mono wafers from JinkoSolar.
