engineering the solar age - Suppliers for Photovoltaics

A full range of critical materials from a global leader in gases and chemicals

The Linde Group is a world-leading gases and engineering company with 48,500 employees working in more than 100 countries worldwide. In the clean energy field, Linde is at the forefront of the emerging hydrogen economy and is active in CO₂ capture & storage and innovative waste-to-energy schemes.

In photovoltaics, Linde supplies gases and chemicals to leading crystalline and thin-film cell manufacturers – its customer base currently has more than 17 GW of installed PV manufacturing capacity across Europe, Asia and the Americas. Our mission is to develop innovative gas and chemical technologies that help solar cell manufacturers reduce costs, increase efficiency and encourage the adoption of environmentally sustainable manufacturing.

Bulk gases

Linde delivers a secure and reliable supply of essential bulk gases, such as nitrogen, oxygen, argon, hydrogen and helium. These products are manufactured by our global network of high purity gas plants and are delivered by road, in liquid or compressed form, to storage facilities on the customers’ sites. Linde offers a comprehensive design and installation service for bulk gas distribution systems, ensuring safe and efficient operation. Alternatively, for large gas consumption, Linde’s ECOVAR systems offer low cost, reliable solutions for on-site generation of nitrogen, oxygen and hydrogen.

Special gases

Linde offers the full range of special gases to support photovoltaic manufacture through a global network of production plants and stock locations. Special gases, including silane, NF₃, ammonia and dopant mixtures, are shipped in a variety of container sizes, depending on application, ranging from cylinders to ISO containers.

Fluorine for chamber cleaning

Linde’s recommended alternative to global warming gases for chamber cleaning, fluorine (F₂), is generated on-demand on customers’ sites. High purity F₂ is the highest performance cleaning gas available, improving productivity on CVD tools and reducing energy consumption and environmental impact, with zero global warming potential.

Wet chemicals

AUECC, a Linde Group company, is a leading supplier of high purity wet process chemicals in Asia and beyond. AUECC provides a full range of standard and proprietary process chemistries for mono- and polycrystalline applications, from silicon manufacturing through to cell fabrication.
