Dear tandemPV 2021 attendees,

Thank you once again for participating in the tandemPV 2021 workshop. We couldn’t have done it without you!

With almost 600 participants from 44 countries, our workshop provided the platform for sharing inspiring and innovative approaches to one of the most exciting topics in today’s PV research and development: Tandem solar cells.
We hope that you had a great time listening to talks, discussing, using the networking features of our online platform, and taking one of our virtual tours of Helmholtz-Zentrum Berlin’s HySPRINT lab.

While the workshop week is over, the recorded content remains available for viewing on the virtual platform under "Recordings" until 16th May (if approved by the speakers). Take some time to catch up on the presentations you might have missed.

Your Opinion Matters. If you have not already completed our brief survey, please take the time to do so here. Your experience during the virtual tandemPV 2021, along with the comments and suggestions you provide, will be important considerations in planning future meetings. The survey will close 16th May 2021.

As already announced during the closing ceremony, the tandemPV 2022 workshop will be hosted by Fraunhofer ISE in Freiburg, Germany. Watch for details coming later this year. 

Again, many thanks for your support of tandemPV 2021. Looking forward to meeting you all next year in Freiburg!

Best regards from sunny Berlin,

the Helmholtz-Zentrum Berlin organizing team
Lars Korte (chair), Steve Albrecht, Silvia Mariotti, Sophie Spangenberger

Last but not least... Congratulations to our winners on your outstanding work and great engagement!
