Evergreen Solar develops, manufactures and markets solar-power products based on its proprietary, low-cost String Ribbon wafer methodology, which uses significantly less polysilicon than conventional ingot processes.

David Chow, president of Praxair China, said: “Evergreen Solar is a valued customer of Praxair in the US, and we look forward to enabling their expansion into China. Praxair is well positioned to serve the rapidly growing photovoltaic market within China, with its comprehensive offering of gas and sputtering target products and its reliable global supply network.”

Praxair’s products, delivery systems and technologies are provided worldwide throughout the photovoltaic supply chain, enabling the production of crystalline and thin-film photovoltaic devices.

Praxair is currently serving more than 50 photovoltaic manufacturing facilities worldwide with a combined capacity of over 6GW.

Praxair gas offerings used in photovoltaic manufacturing include bulk, onsite and specialty gases such as silane, ammonia, high purity argon, nitrogen, hydrogen, phosphorous and boron dopants, and associated gas delivery systems.

Praxair also offers a full suite of planar and tubular sputtering targets for the deposition of metal and transparent conducting oxide thin-film layers which are critical to the performance of photovoltaic devices.
