Fraunhofer ISE recently confirmed that Kaneka and imec’s six-inch, semi-square, heterojunction silicon solar cell has a certified power conversion efficiency of 22.68%. The solar cell has an electroplated copper contact grid on top of a transparent oxide layer, which essentially replaces the traditional silver screen printing and is said to lead to higher efficiencies with lower manufacturing costs.
Taiyo Pacific Partners has upped its stake in Japan-based Ulvac to 18%, following its purchase of a 5% shares stake in September 2009. Taiyo is now Ulvac’s largest shareholder Pacific Partners and has, since its initial investment in 2009, acted as a “long-term friendly investor providing valuable advice and support”, according to Ulvac’s president Hidenori Suwa.
Flexible CIGS module manufacturer Global Solar Energy has initiated the steps to attract new investment, enlisting the services of FTI Capital Advisors to investigate new investor participation that could see the partial or complete takeover of the company.
Thin-film CIGS manufacturer AQT Solar has announced its completion of a significant phase of its CZTS prototype module development, producing a 60-watt module in collaboration with its manufacturing partners. Earlier this year, the company revealed that it had achieved high efficiencies with its sputter-deposited CZTS thin-film solar cell.
The Cambridge, Massachusetts-based Fraunhofer Center for Sustainable Energy Systems (CSE) has appointed CPV expert Geoffrey S. Kinsey, Ph.D. to the role of director of its Photovoltaic Technologies Group. Dr. Kinsey joins the organization from his former role as senior director of R&D at Amonix, where he led a team working on the optimization of III-V multijunction cells for solar power generators, recently reaching a module efficiency of 33% in outdoor operating conditions.
As the largest merchant solar cell producer, JA Solar continues to be impacted by rapidly declining prices as overcapacity continues thought the supply chain. Emphasis has therefore shifted to module production and shipments, though a return to profitability remains a distant goal. First quarter shipments which included cells and modules that exceeded guidance at 366MW, while revenue reached US$254.4 million, down 17.7% from the prior quarter and 56%, year-on-year. Net loss for the quarter was US$39.8 million.
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.
