Solar experts meet in Berlin

The sixth tandemPV Workshop will take place in Berlin, Germany from June 17-19, 2026, hosted by Helmholtz-Zentrum Berlin.

The tandemPV Workshop Series is a unique platform that brings together leading experts and researchers from the silicon and thin-film photovoltaic communities, fostering collaboration and innovation.

Our PV experts will join the workshop and participate with various contributions. Take your chance and meet them for interesting discussions about our recent research!
In addition, participants will have the opportunity to take a guided tour of our laboratories and research facilities.

Workshop highlights:

• Interdisciplinary collaboration
  
• Silicon and thin-film integration: Engage with experts from both silicon and thin-film sectors, exploring the latest advancements and synergies in photovoltaic technology. This unique integration aims to harness the strengths of both materials, pushing the boundaries of efficiency and performance in solar cells.
• Material scientists and device specialists: Connect with professionals across the material science and device engineering spectrum. This is an opportunity to share insights and breakthroughs, fostering a collaborative environment where ideas can be exchanged, and new collaborations can be formed.
