Manufacturing

Thin-film module manufacturing costs took a significant fall in the second quarter as First Solar continued to lead the PV industry in the lowest cost-per-watt race.

In a significant change of direction, Applied Materials has revealed that it will stop selling its turnkey a-Si thin-film technology under the SunFab name to potential new customers, shifting emphasis away from thin-film altogether and focusing on crystalline silicon (c-Si) and LED manufacturing equipment and technology.

At Intersolar Europe 2010, a powerhouse of the semiconductor industry exhibited for the first time but based on their manufacturing strategy will be attending this and many other major events for years to come. As is typical of the Korean-based memory manufacturer, little has actually been revealed about their solar manufacturing strategy, especially capacity and capital spending plans. However, PV-Tech was granted an exclusive video interview with the head of its new Solar Energy division, Changsik Choi, Executive Vice President, Samsung Electronics.

Mitsubishi Electric has said that it has completed construction of PV Cell Plant #2, a 50MW solar cell production facility at its Nakatsugawa Works Iida Factory in Nagano Prefecture. When ramped in 2011, the new plant will give Mitsubishi an annual capacity of 270MW. The company noted that the new facility will also produce monocrystalline-silicon cells and start production by March 2011.

Organic photovoltaics developer Solarmer Energy has achieved the highest conversion efficiency recorded so far for a plastic OPV champion cell—7.9%. The aperture-area test results, recently certified by the U.S. Department of Energy’s National Renewable Energy Laboratory, represent an improvement over independent exams conducted a few months ago at Newport Corp.’s Technology and Application Center’s PV Lab, where cell efficiencies of 7.6% and module efficiencies of 3.9% were recorded.

The race to higher conversion efficiencies in volume production for both monocrystalline and multicrystalline cells continues with news that Canadian Solar plans to boost cell performance to 18.5% and 16.8%, respectively. This will be accomplished by using several advances that include improvements in screen printing techniques, better texturization and a modified selective emitter process. The company said that these successful R&D projects will be migrated to production lines in the fourth quarter of 2009.

Allora Minerals has been busy, acquiring the remaining assets of OptiSolar, receiving preliminary approval to garner millions of Euro in grants for German projects, and getting shareholder approval to change its name to that of another company whose assets it's buying, EPOD Solar (ESI). The OptiSolar deal will bring the once-promising thin-film PV company's intellectual property and its manufacturing and R&D facilities in Northern California into ESI's portfolio.

DuPont and the U.S. Department of Energy will collaborate in a $9 million solar research program to develop ultrathin moisure-barrier material solutions for flexible thin-film photovoltaics. Some $3 million of the funding for the three-year effort comes from the American Recovery and Reinvestment Act, with DuPont contributing the remaining $6 million.

Roth & Rau AG has acquired Ortner cleanroom logistic systems GmbH for an undisclosed sum in an effort to meet increasing demand from customers to support crystalline and thin-film equipment servicing, spare parts and other support activities. Ortner, based in Dresden, is a specialist in tool installations and automation company. Ortner’s existing management and skilled workforce will continue to operate the business as a subsidiary of Roth & Rau.

Researchers of hybrid solar cell fabrication at Ludwig-Maximilians University (LMU) in Munich have ordered an advanced sputtering tool from U.K.-based Surrey NanoSystems. The tool will be used in the creation of high-efficiency interconnection templates for organic materials, thereby greatly increasing the efficiency of the cells, according to LMU.
