Digital Twin - Solar TAP

We are proud to highlight the excellent scientific contribution of Marie-Louise Schubert, PhD researcher at the Karlsruhe Institute of Technology (KIT) in the group of Prof. Carsten Rockstuhl, whose work was selected among the Poster Award Winners at the EU PVSEC 2025.

Her poster, “Towards a Fully Differentiable Digital Twin for Solar Cells: Simulation Steps”, presents a key advancement toward a digital twin framework for photovoltaic devices. The project integrates morphology, optical simulation, electronic transport, and energy yield prediction into a unified, partly machine-learned workflow. The approach enables faster optimization and improved design of next-generation PV technologies.

The work closely aligns with Solar TAP’s mission to accelerate solar innovation through data-driven design, multiscale modeling, and digital workflows.

“Digital twins offer a powerful way to speed up PV development and connect material insights with device performance. This award-winning work is an excellent example of that potential.” — Solar TAP Manager, Dr. Jens Hauch

Solar TAP congratulates Marie-Louise Schubert and the project team on this recognition and their contribution to advancing digital twin technologies for photovoltaics.

Workshop Review: Towards a Digital Twin for Emerging Photovoltaics

From June 30 to July 1, 2025, over 25 researchers, students, and industry professionals gathered virtually across two afternoons to explore the current landscape and future directions of digital twin approaches for emerging photovoltaic (PV) technologies. The workshop provided a platform for exchange across various disciplines and perspectives, spanning from materials science to device simulation and systems engineering. Participants included PhD students, postdoctoral researchers, professors, and representatives from industry. Companies such as JCMwave and Fluxim shared their current simulation approaches and research tools, adding valuable applied insight to the discussion.

The program on Day 1 provided an overview of the Solar TAP initiative, with sessions on morphology formation (Olivier Ronsin, HI ERN), optical simulation (Carsten Rockstuhl, KIT), and photonic modeling using JCMsuite (Sven Burger, JCMwave). These talks emphasized the role of structural and optical modeling in the development of digital twins.

Day 2 focused on device-level modeling using SETFOS (Urs Aeberhard, FLUXiM), energy yield modeling (Seyedamir Orooji, KIT), and the application of machine learning and optimization techniques (Pascal Friederich, KIT).

Together, these sessions illustrated how Solar TAP aims to unify a diverse set of modeling tools—from material morphology to system performance—into a comprehensive digital twin framework for flexible, printed, and emerging PV technologies.

The workshop was coordinated by Marie Louise Schubert (KIT) and Carsten Rockstuhl (Solar TAP PI). It brought together researchers from academia and industry to collectively advance the development of digital twins for next-generation photovoltaic systems.

We thank all speakers and participants for their inspiring contributions and look forward to further collaboration within the Solar TAP community.
