Use the whole spectrum!

Welcome to the 2nd International tandemPV Workshop!

The 2nd edition of the tandemPV Workshop will take place from May 30 to June 1, 2022 and will be hosted by Fraunhofer ISE, Germany. The workshop will take place as a hybrid event in the brand new soccer stadium of SC Freiburg in close proximity to the Fraunhofer Institute for Solar Energy Systems (ISE) and only a few tram stops away from the beautiful historic city center of Freiburg. We are sure that this stimulating environment will provide space for a lively personal exchange and inspiring discussions.

Register now to get your ticket for the tandemPV 2022 Workshop and attend either on-site in Freiburg, or online! 



Like last year’s tandemPV Workshop held in Berlin in April 2021, tandemPV 2022  encompasses the full range of related topics:

  • Day 1: Materials Research for Tandem Solar Cells
    The first day will be dedicated to materials research, discussing the challenges in top and bottom cell materials including carrier selective contacts and interconnection layers for tandems.
  • Day 2: Tandem Solar Cell Devices and Modules
    On the second day, we will focus on tandem devices, with a special focus on silicon-based tandem cells such as perovskite-silicon solar cells. We will also look at other technologies like CIGS- or III-V based multijunction cells or pero-pero tandem cells. Since the interconnection and encapsulation of tandem cells raises new challenges, module technology will be another important topic.
  • Day 3: Upscaling – Industrialization – Yield
    The workshop will be rounded off on the third day with an industry day, where topics such as upscaling, industrialization and long-term stability of tandem cells and modules will be covered.

Join the tandemPV workshop either online or on-site and keep up to date on all aspects on Materials Research for Tandem Solar Cells, Tandem Solar Cell Devices and Modules, Upscaling – Industrialization – Yield.

Leading scientists will give an overview of the latest developments in the field and the program will also include lively panel discussions and poster sessions. So finish your experiments, simulations, and measurements and get ready to write your abstracts! We are looking forward to your contributions.
