Materials & Technologies for Crystalline Silicon Photovoltaics

As part of our commitment to the latest process technologies, we are currently driving the trend from wet to dry processing. Building on our expertise in thin-film silicon solar, our dry processing technologies are enabling smarter crystalline silicon manufacturing processes. Benefits include lower operating costs plus increased fab efficiency and performance. We also have the experience and expertise to optimise critical process steps such as etching/texturisation, doping, PSG removal, edge isolation, anti-reflective coating (ARC) deposition and various cleaning steps that are essential to cell performance.



Full spectrum

We offer the full range of gas and chemical products to support all crystalline silicon cell manufacturing processes:

• Ultra-pure bulk gases 

• Electronic special gases in cylinder and bulk supply

• Special and wet process chemicals.
