Imports from South Korea and the U.S. dwindled, year-on-year, ensuring Germany’s Wacker and the Malysian unit of Korean company OCI will supply the bulk of the world’s non-Chinese solar polysilicon this year.

The Norwegian polysilicon maker has been been frozen out of the Chinese solar market by political tensions between Beijing and the U.S. and mothballed its Washington State production line last year. However, two recent business agreements could change all that.

But Israeli inverter company Solaredge and Indian engineering, procurement and construction services provider Sterling and Wilson have both offered hope of a recovery in Europe as Chinese glass producer Xinyi said it kept the furnaces going throughout the worst of the pandemic.

The Norwegian company mothballed its Washington State facility more than a year ago and is now reliant on semiconductor-grade poly and silane gas produced at its fab in Butte, Montana – a facility for which the business says it has received plenty of interest from potential purchasers.

Zero-emission, low-cost regional flights with just eight other sanitized folk and a disinfected pilot! Yes, Covid-19 is warping our view of the future but the successful electrically-powered maiden flight of a Cessna Caravan last week offers the potential for new modes of transport to support a wider economic recovery in Australia.

Scientists in the United States have developed a carbon nanotube method of fabricating a lithium-ion battery with a silicon anode. The device reportedly demonstrated better than 87% capacity retention after 1,500 cycles. The developers say their discovery overcomes many of the obstacles to the use of silicon as an anode and could open up the use of other materials for electrodes in lithium-ion devices.

Finnish lender Nordea has called in a NOK150 million indemnity loan thought to have been taken out by REC Silicon ASA as a result of the bankruptcy of its Norwegian wafer manufacturing arm seven years ago.

A technique based on optical imaging has been used by an international research team to illuminate strains in lead halide perovskite solar cells without harming them. The scientists claim the approach helped them discover misorientation between microscopic perovskite crystals was the main cause of the strains.

The Norwegian polysilicon and silane gas producer has announced it will listen to offers for its production facility in Butte Montana after mothballing its other manufacturing operation – at Moses Lake, Washington – in the summer.

The Norwegian polysilicon supplier – which has most of its manufacturing operations on U.S. soil – cannot give any estimate on when its solar material production lines will return, and has been left entirely dependent on the semiconductor products made by its Montana facility.
