Tungsten and molybdenum have been successfully used as thin films for TFT displays for more than twenty years. We supply sputtering targets to the solar industry for use in the following technologies:

 

• CIGS (copper, indium, gallium, sulphur, selenium)
• CdTe (cadmium telluride)
• CSP (Concentrated Solar Power)

 

When used as coating components, our materials help determine the performance of thin-film photovoltaic and solar thermal applications. They are highly adhesive and resistant against oxidation and corrosion. Sputtered films made of our materials are not only highly reflective and extremely conductive but can also significantly increase the efficiency of solar cells. In addition to sputtering targets made from pure molybdenum, tungsten and chromium, PLANSEE also manufactures molybdenum alloys such as MoNa and the corrosion resistant MoTa. For absorber layers we offer targets made of CuGa, CuInGa and CuIn.

120 scientists, experienced engineers and state-of-the-art equipment get the very best out of our materials. The benefit to you: stable coating processes and homogeneous films.

 

• Long service life due to optimized film adherence
• Highly efficient thanks to the excellent electrical conductivity resulting from the use of extremely pure materials
• High sputtering speeds due to maximized material densities
• Uniform sputtering rates thanks to the optimized microstructure
• Stable sputtering processes due to the high level of resistance against oxidation and corrosion 

More speed: Our monolithic targets can be used without backing tubes. They can be sputtered at power densities of up to 30 kW/m. This results in higher sputtering speeds and optimized film properties.     Improved yield: The intelligent target geometries of our u-shaped and dogbone targets, for example, permit material utilization levels of even more than 75 % and thus longer target lifetimes. The principle is simple: We apply more coating material to the areas that are subject to the highest load levels. This allows us to overcome the disadvantages of conventional designs – uneven sputtering and high levels of material loss.     More energy: Thanks to our new material compositions, we are able to increase the efficiency of the absorber layer. So every ray of sun gives you more!

We are the only manufacturer of sputtering targets to perform every stage of the production process ourselves. From the raw material through to the finished product: including the development of new materials and the optimization of our coating methods and coatings.

 

Sintering is the cornerstone of our powder metallurgical production process. This is the method we use to manufacture compact metallic components from porous powder blanks. With the world's largest hot rolling mill for refractory metals, we produce planar targets of maximum density. We use special forming processes to manufacture our rotary targets.

Since 1921, our customers have been able to rely on PLANSEE as an independent private company. For us, reliability and continuity are particularly important qualities. For example, our sister company GTP, provides our customers with top-quality tungsten powder, while we safeguard the long-term supply of molybdenum through the Plansee Group's holding in the South American molybdenum producer Molymet.

Let's join forces to move solar technology forward. We work together with all the leading system manufacturers and numerous research institutes. The result is innovative materials and coatings that we sputter and specify under real-life conditions. And naturally, our application laboratory is also available to you.

 

We will coat test substrates using the RF, DC or pulsed DC sputtering methods in line with your specifications. Using a high-resolution scanning electron microscope and other analytical equipment, we can identify the microstructure, electrical conductivity, adhesion, film thickness and film stresses. We check the crystallographic phase, optical properties, chemical composition and morphology of the deposited films. We are happy to send you a vacuum-packed film sample for further examination.

Molybdenum and tungsten are both able to withstand extreme temperatures and aggressive chemicals. These are the materials we use to manufacture systems components for your coating process: Shieldings, evaporation boats, hot zones, formed crucibles, pressed-sintered crucibles, glass melting electrodes and many other components.
