Contact Firing Process for Contacting Silicon Solar Cells.

The printing of functional fluids requires not only high-precision printing and coating processes, but also suitable drying and sintering processes. Various highly specialized drying and sintering technologies are available at Fraunhofer ISE for this purpose. In addition to classic continuous dryers based on IR radiation and convection, high-temperature sintering processes (contact firing) as well as innovative processes such as Vertical-Cavity Surface-Emitting Laser (VSCEL) and Intense Pulsed Light (IPL) with flash lamps can be realized in the PV-TEC (Photovoltaic Technology Evaluation Center of Fraunhofer ISE).



Our Infrastructure and Services for Drying and Sintering Technology:

  • Inline and offline drying, curing and sintering equipment for low and high temperature sintering pastes as well as inert high temperature sintering furnace
  • Firing furnace with extended peak firing zone and integrated IR camera for process monitoring
  • Special drying/firing technology (UV, Intense Pulsed Light (IPL) and VCSEL technology). Detailed simulation services.
