- Inventux Technologies AG, the Berlin-based thin-film solar module manufacturer, has contracted Linde Nippon Sanso (LNS), a company of The Linde Group, to provide the full range of high purity gases used in the manufacturing process of their new Berlin plant.

The long term contract comprises turn-key gas systems engineering plus exclusive supply of all gases to the solar

cell production line including onsite generated bulk nitrogen (N(2)), oxygen (O(2)), hydrogen (H(2)) and silane (SiH(4)), as well as all cylinder gases. LNS will also provide an onsite Total Gas Management service. Gas was turned on at the end of June 2008, with the first thin-film modules expected to leave the 33 MWp factory soon after.

"We are extremely proud to be working with Inventux for this leading-edge project," said Andreas Guenther, President of Linde Nippon Sanso. "This collaboration with a pioneering manufacturer reinforces our goal to develop and apply advanced gas technologies to help solar cell and module manufacturers move toward grid parity."

Volko Loewenstein, CEO of Inventux, said "LNS impressed us as a partner who can help reduce the cost of thin film solar modules by deploying innovative gas technology in areas such as chamber cleaning gases. Additionally, with supplies from the state of the art electronic gases plant in Unterschleissheim, security of supply is assured."

Inventux is one of the earliest users of the micromorph tandem technology, a process that has the potential for high efficiencies and low production costs. Instead of a single light trapping layer, tandem uses two different layers in the cell - one working with the blue part of the light spectrum, and one with red - to boost efficiency by more than 40%.
