Fraunhofer ISE Hosts the 8th Back Contact Workshop in Freiburg


The Fraunhofer Institute for Solar Energy Systems ISE is collaborating with the Energy Research Centre of the Netherlands (ECN) to organize the 8th Back Contact Workshop, which will be held in Freiburg from November 21–22, 2017. The workshop focuses on back contact technology for solar cells and modules. This technology involves fitting the contacts entirely on the rear side of the solar cells in order to improve sunlight absorption on the front side.

The world’s most efficient silicon solar cells boasting efficiency values of 26.7% are based on back contact technology. In addition to highly efficient solar cells and modules which are already successfully being manufactured, the workshop also shines a spotlight on materials and components, as well as industrial production and alternative applications which use back contact technology. The workshop will be held at the Freiburg Solar Info Center in Freiburg. Abstracts can still be submitted until August 31, 2017.
