GCL-Poly’s silicon materials arm plummets to a US$150 million loss in 2019

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 expects a challenging year for polysilicon business

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.

Daqo pushes down polysilicon production costs to record US$7.94/kg

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 expects strong rebound in solar demand in 2019

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.

Beyond boron-oxygen-deactivation: industrial feasible LID-free p-type Czochralski silicon

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.

Wacker’s polysilicon division sales plummeted 27% in 2018

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.

GCL-Poly to expand new Xinjiang polysilicon production plant to 60,000MT

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.
