Update: A significant increase in production capacity of its leading-edge ‘Panda’ technology will help boost Yingli Green’s total PV production capacity pass 1.7GW by mid-2011. Yingli Green is adding 600MW of new capacity in each key area of monocrystalline silicon manufacturing, which includes ingots, wafers, cells and modules at its Baoding, China headquarters. A further 100MW will be added to multicrystalline silicon production, in Haikou, Hainan Province, China. Yingli’s

Once a leading in-house solar module manufacturer, BP Solar has further solidified its outsourced manufacturing strategy by awarding JA Solar a monocrystalline and multicrystalline cell supply contract exceeding 185MW. The new supply deal will see 100MW of cells shipped to BP beginning in the first quarter of 2011.

The Stuttgart-based researchers at Zentrum für Sonnenenergie- und Wasserstoff-Forschung Baden-Württemberg, Germany (Centre for Solar Energy and Hydrogen Research, ZSW) have demonstrated a CIGS solar cell conversion efficiency of 20.3%. The area of the world record cell is 0.5 square centimetres and surpasses their previous record of 20.1%, established in April 2010.

High-purity materials supplier 5N Plus has signed a long-term supply agreement with cadmium-telluride thin-film module producer Abound Solar. Under the terms of the deal, 5N Plus will provide CdTe compounds to be used in the manufacturing of Abound's PV panels.

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.
