Indium Corporation will feature its enhanced copper-indium-gallium (CIG) and copper-gallium (CuGa) rotary sputtering targets and its full family of PV Module Assembly Materials at the 27th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC) on 25-28 September 2012 at the Messe Frankfurt fairground (hall 3.0, booth D21) in Frankfurt, Germany.
The sputtering targets are now available in lengths up to 3.2 metres (~10.5 feet) and with monolithic source layer thicknesses up to 22 millimetres (~0.9 inches). They are produced in Indium Corp.'s vertically integrated, proprietary manufacturing process utilising aerospace powder metallurgy technology. This creates a consistently homogeneous alloy with low parts per million (PPM) contaminate levels and uniform density, resulting in consistent sputtering film properties and performance.
Indium Corp.'s targets are produced as a monolithic material, bonded onto the backing tube using the company's unique hybrid consolidation process. This process provides the user with consistent performance in both the standard copper-indium-gallium-selenium (CIGS) chemistry ranges and when using unique chemistries for the research and development (R&D) and engineering communities.
Included among the company's PV Module Assembly Materials is Indium Corp.'s industry-adopted GS-3434 No-Clean Liquid Tabbing Flux. While most fluxes used in the industry were developed for wave soldering applications, Indium Corp. formulated GS-3434 specifically for photovoltaic (PV) soldering. GS-3434 provides excellent bond strengths on a variety of silver-aluminium (AgAl) metallisations for both tin-lead (SnPb; i.e., solder) and lead-free processes. The material's unique formulation enables its use in both spray and flux bath applications, leaving a minimal clear residue for no-clean operations. Its quick activation at low temperatures also enables the use of alternate PV ribbon alloys.
Indium Corp. manufactures and distributes materials for thin-film physical vapour deposition (PVD) and module assembly. Module assembly materials include SunTab PV ribbon, liquid tabbing fluxes, low temperature metallisation paste, flux-cored wire and solder preforms. Indium Corp. also manufactures NanoFoil, which provides instant heat energy for bonding applications.
