Solarfun has joined JA Solar and Yingli Solar to become the third Chinese crystalline-silicon PV cell manufacturer to sign a licensing agreement with Innovalight for the Sunnyvale, CA-based company's proprietary performance-enhancing nanosilicon ink process.

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.

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.

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.

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.
