Perovskite and organic PV offer the potential for low-cost, lightweight, and flexible solar cells that can be produced using scalable, solution-based manufacturing. While perovskite and organic solar cells can be sensitive to moisture, oxygen, heat, and light, especially the exposure to elevated temperatures and illumination is unavoidable during operation of PV modules.

Within the Light-2-Last Lab of the Autonomous Discovery of Advanced Materials department the research focuses on high throughput characterization of the stability of active PV absorber materials under accelerated irradiation and temperature conditions. We use a closed-loop experimentation strategy assisted by Machine learning (ML) algorithms on a Material Acceleration Platform (MAP) under controlled atmosphere. The MAP consists of the deposition of active layers, an accelerated light and temperature induced degradation stage as well as of various advanced optical characterization methods to monitor photo-physical material properties in-situ (during degradation) and ex-situ (before, between and after degradation steps).

In addition, we maintain and operate the JuPREMe Lab – The Juelich Photovoltaic Research and Education Mobile Laboratory. It focuses on the training and education of students and skilled workers in the field of photovoltaics. More information about JuPREMe Lab can be found here.
