Fraunhofer Institute for Solar Energy Systems ISE
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).
