With polysilion spot prices heading for the low US$20/kg territory and well below small polysilicon producers' production cost levels, Motech Industries has decided to exit the polysilicon sector with the shutdown and sale of assets of its subsidiary, AE Polysilicon Corporation (AEP). Motech invested in AEP in 2006 as it started the development of high purity granular polysilicon, intended to provide lower cost polysilicon compared to conventional Siemens processes.
Ensuring sufficient future supply of its ‘Tedlar’ polyvinyl fluoride (PVF) film for PV module assembly requirements has been completed, according to DuPont. The US$295 million investment in new capacity has more than doubled production, the company said.

The former BP Solar module assembly plant, originally closed in 2009 but resurrected by Silex Systems to provide modules in the Australian market has also closed the facility. The company said that it couldn’t operate the facility on a profitable basis as market demand in Australia had waned.
The US Department of Energy's National Renewable Energy Laboratory (NREL) has confirmed a 15.5% aperture area efficiency on commercial size flexible PV module (total area 1.68m2) from thin-film manufacturer MiaSolé. MiaSolé’s record represents over 2 points of improvement compared to the previous world record for flexible PV of 13.4% set earlier this year by SoloPower.
A new 44MWp module assembly plant in the De Vernejoul industrial park in Porcelette, Eastern France will assemble SunPower’s Maxeon solar cells into modules to meet demand in France, Italy, Germany and Belgium. Total and SunPower said that its 3,300-square-metre plant is equipped to produce approximately 150,000 high efficiency (20% conversion efficiency) modules per year. This is the first such plant SunPower will operate in Europe, having the majority of its production in the Asia-Pacific region.
Hoku Corporation released a statement advising of the current state of the company, which included a confirmation that it had stopped all construction activity for its Hoku Materials polysilicon production site, which is not yet in commercial operation.
