Fraunhofer ISE and teamtechnik Demonstrate Industrial Maturity of Electrically Conductive Adhesives for Silicon Solar Cells

The Fraunhofer Institute for Solar Energy Systems ISE and teamtechnik, an international leader in production technology, report that it is now possible to connect high efficiency solar cells using electrically conductive adhesives in series production. The results of the joint research project »KleVer« show that the adhesive technology is ready for the market and can be used as an alternative to the widespread soft soldering interconnection technology. Due to the much lower process temperatures of this technology compared to soldering, temperature-sensitive high efficiency solar cells can be connected using adhesives in a gentle and material-saving process. In industrial production, the throughput is only slightly lower than with soldering. The reliability of the adhesive connection was confirmed in tests carried out in a climate chamber.
