As part of its long-term cost reduction goals for its turnkey Micromorph thin film silicon ‘ThinFab’ production lines, Oerlikon Solar has teamed with gas suppliers Air Liquide and Linde to provide more than a 20% reduction in total cost of all gases and precursors. As a result, its ThinFab (120MWp) lines going into full production by end of 2012 can reduce module production costs by up to 5%. The total gas budget was said to be less than €8.50 per panel.
Semiconductor equipment supplier, Novellus Systems is developing what it describes as conformal film deposition (CFD) technology, an atomic layer deposition process to grow conformal metal oxide and metal nitride dipole layers in the PV cells. Collaboration is being undertaken with the University of South Florida (USF), to study the precise engineering of solar cell interfaces via a National Science Foundation (NSF) grant.
David Brady, First Solar’s VP of Treasury is also taking over the role of Investor Relations, reporting to Mark Widmar, Chief Financial Officer. Former investor relations officer, Larry Polizzotto remains within the company, though no formal position has been chosen. Reasons for the shuffle were not given.
Pushing the boundaries of conventional silicon solar cell technology, while offering a low-cost production approach, took another step forward, according to R&D organisation, imec. In conjunction with its industrial affiliates, researchers have developed a small-area (2x2 cm2) - interdigitated back-contact (IBC) silicon solar cells that has demonstrated a conversion efficiency of 23.3%. Work will now focus on developing a large-area and production viable cell and process steps.
At Suntech Power Holdings’ recent Global Supplier Conference, the company recognized 19 companies with its award ceremony, one of them being DuPont, which was honored for its supply and technical service as well as its product innovation and collaboration. DuPont provides Suntech with its Solamet PV metallization pastes for its solar cells and also supplies Suntech’s backsheets with the DuPont Tedlar polyvinyl fluoride film.
Verified by the Fraunhofer ISE Institute, CIGS (Copper Indium Gallium Selenid) thin-film manufacturer, Solibro a subsidiary of Q-Cells has reported a CIGS test module has achieved a new world record conversion efficiency of 17.4%. Earlier this year Solibro produced a record full-module reading of 14.7% in series production.
Fraunhofer ISE and Azur Space Solar Power advised that the 15 year partnership for the creation of multi-junction solar cells using III-V semiconductors has been extended for another 20 years by the signing of an agreement of cooperation. Fraunhofer and Azur Space plan to work together over the next two decades to create solar cells that will be used for applications based in space.
Orders from Canada and Azerbaijan for Vitrododi solar glass washers are now being built at a Rimas factory in Holland for Rimas PV manufacturing lines. Vitrododi Solar was acquired by Rimas in July, 2011.
Third quarter results from Hanwha SolarOne echoed pricing pressure and weak demand, especially from Germany that led to margin pressure, inventory write downs and losses. Hanwha SolarOne reported US$225.4 million in revenue, a decrease of 20.1% from 2Q11 when revenue reached US$277.1 million. The company recorded a non-cash inventory write-down of US$30.6 million and a net loss of US$46.4 million.
Tata Steel and Dyesol are continuing with their progress on the production of what they hope will be the world’s largest dye solar cells modules (DSC). The team has been constructing a DSC 20m2 roof array that will be tested at the Sustainable Building Envelope Centre
(SBEC) test facility in Shotton, Wales.
