A day after reports claimed Hanergy and Q-Cells were in discussion over the sale of the German PV manufacturers' CIGS thin-film subsidiary, Solibro, both companies said in a statement that a deal had been signed. Financial terms were not disclosed.

Reports have emerged that Hanergy Solar Technology is considering the purchase of Solibro, the CIGS thin-film subsidiary of Q-Cells. Insolvency firm HWW Wienberg Wilhelm, which is administering the bankruptcy proceedings of Q-Cells had said in April that there had been both foreign and domestic interest in acquiring the bankrupt PV manufacturer.

Failure to secure further funding has forced flexible thin-film manufacturer, Konarka Technologies into bankruptcy. The Chapter 7 bankruptcy via a Massachusetts Bankruptcy Court means full liquidation and asset sale to pay creditors. Since its initial venture capital funding in 2001, the company had raised around US$190 million to develop and market its roll-to-roll OPV (organic photovoltaic) technology.

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. DuPont has recently secured long-term agreements with Tier 1 PV module manufacturers such as Suntech, Yingli Green, Trina Solar and China Sunergy.

Swiss silicon thin-film firm, Pramac has been forced to file for insolvency after shareholders rejected management proposals over restructuring the company after posting losses (net) of over €94 million in 2011. The diversified firm had been a customer of Oerlikon Solar since 2008. Pramac had a 30MW end-to-end turnkey line using Oerlikon’s ‘Micromorph' technology.

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.
