China-based polysilicon producer Daqo New Energy is upgrading CVD chambers and debottlenecking to enable mono-grade polysilicon production to account for approximately 80% of capacity, due to strong demand and higher ASPs, compared multi-grade polysilicon.
Major polysilicon producer Wacker Chemie has continued to be impacted by record low polysilicon prices, due to overcapacity and weak demand caused by China’s ‘531 New Deal’ and lack of new support policies in China since June, 2018.
Major China-based polysilicon producer and PV project developer, Xinte Energy Co has issued a profit warning for the first quarter of 2019, due to further polysilicon price declines. Xinte is a subsidiary of TBEA Co.
Leading polysilicon and multicrystalline solar wafer producer, GCL-Poly Energy Holdings has reported a loss of RMB 1,011.4 million (US$150.7 million) for its ‘Solar Material Business’ unit in 2018, citing the demand impact from the China 531 New Deal that led to overcapacity and rapidly falling selling prices.
Wacker Chemie has reported a 27% decrease in revenue for its polysilicon division, due to a marked decline in demand from China and a fall in average selling prices (ASPS). Weak pricing is expected to continue in 2019, lowering profitability further.
China-based polysilicon producer Daqo New Energy Corp said that its polysilicon production costs in the fourth quarter of 2018 had declined to a record US$7.94/kg. The company is targeting to reach US$6.80 per kilogram in 2020, once the capacity expansion to 70,000MT per annum has been completed.
ROTH Capital Partners has become increasingly bullish on a strong rebound in global solar demand in 2019, led by competitive pricing dynamics with other energy sources and increasing optimism that China will provide good subsidy support for solar in 2019 and onwards.
China-based polysilicon producer Xinte Energy Co, a subsidiary of TBEA has secured a major supply deal with wafer producer Wuhai Jingyuntong New Materials Technology Co, a subsidiary of Beijing Jingyuntong Technology Co (JYT).
Today’s industry standard B-doped monocrystalline silicon still suffers from light-induced degradation of the carrier lifetime. Illumination at elevated temperature leads to a so-called regeneration, i.e. a recovery of the carrier lifetime as well as the solar cell efficiency. However, even though the carrier lifetime on test wafers increases from about 1 ms after processing to 3 ms after regeneration, the corresponding PERC+ cell efficiencies in both states are identical. We discuss possible reasons for this discrepancy. Additionally, we evaluate B-doped Czochralski silicon wafers with an ultra-low oxygen content of 2.6 ppma as well as industrial Ga-doped wafers. Both wafer materials are completely LID-free in lifetime measurements and PERC+ cell efficiencies and enable up to 0.4%abs higher efficiencies than present industry-typical boron-doped wafers.
Major polysilicon producer Wacker Chemie has reported its polysilicon division was heavily impacted by the slump in demand due to China’s ‘531 New Deal’ as a reason for the sharp decline in revenue and profitability which declined significantly in 2018.
Leading polysilicon and solar wafer producer GCL-Poly Energy Holdings has announced that its new Xinjiang polysilicon production plant’s annual nameplate capacity will be increased to 60,000MT, up from the revised plans mid-year to increase the capacity from 40,000MT to 50,000MT.
Major polysilicon producer Wacker Chemie has reported a significant decline in the fortunes of its polysilicon business segment in the third quarter of 2018.
The Chinese government’s decision (531 New Deal) to curtail utility-scale and distributed generation (DG) PV deployments just after the SNEC trade show at the end of May, not only surprised the industry but has since fuelled a significant ASP decline of modules and inverters.
China-based polysilicon producer Daqo New Energy Corp said that its polysilicon production costs were targeted to reach US$6.80 per kilogram in 2020, once the capacity expansion to 70,000MT per annum had been completed.
