Abkehr von der Kernenergie, Ausbau von Solar- und Windkraft, Energiegewinnung aus Biomasse, Senkung des Energieverbrauchs. Bis 2050 soll die Schweiz klimaneutral werden. Ein ehrgeiziges Ziel, welches durch die zunehmend herausfordernde geopolitische Lage dringlicher denn je geworden ist. Wie lässt sich in den nächsten Jahren eine nachhaltige und widerstandsfähige Energieversorgung für die Schweiz aufbauen? Wie können erneuerbare Energien optimal genutzt werden? Welche neuen Technologien sind besonders vielversprechend? Am PSI suchen Forschende nach Antworten auf diese entscheidenden Fragen.

Flat-band hybridization between f and d states near the Fermi energy of SmCoIn5
We present high-quality angle-resolved photoemission (ARPES) and density functional theory calculations (DFT+U) of SmCoIn5. We find broad agreement with previously published studies of LaCoIn5 and CeCoIn5, confirming that the Sm 4f electrons are mostly localized. Nevertheless, our model is consistent with an additional delocalized Sm component, stemming from hybridization between the 4f electrons and the metallic bands at “hot spot” positions in the Brillouin zone.
Efficient transient X-ray absorption spectroscopy
By combining the unique large bandwidth emission mode of SwissFEL’s ARAMIS undulator and diffractive X-ray optics made of diamond, we have demonstrated a new method for time-resolved X-ray absorption near edge structure (XANES) spectroscopy that enables faster data acquisition and requires smaller sample quantities for high-quality data.

Unraveling degradation processes in a bipolar membrane CO2 electrolyzer by time-resolved X-ray tomographic microscopy
Employing a bipolar ion conducting membrane (BPM) in forward bias is a convenient solution for the biggest issues in the more common anion exchange membrane (AEM) CO2 co-electrolysis: the degradation of the performance caused by carbonate salt precipitation at the cathode and the decrease of net CO2 conversion caused by the crossover of this molecule from cathode to anode also requiring energy for downstream gas separation. However, the performance and stability of this device remain largely insufficient when using such a BPM configuration. To understand the reasons for this, we performed time-resolved X-ray tomographic microscopy of an operating BPM CO2 electrolyzer. The imaging method reveals partly unexpected degradation processes that result in design recommendations for improvement.
