Just back from #HOPV2025 in Rome — three days full of intriguing science, great company and amazing food in a historic atmosphere 😊 Grazie to the organizers and everyone who made it such an inspiring and fun event. Already looking forward to the next one!

Struggling with thermal evaporation of perovskites? We found in our recent study that the interface can make or break your mixed halide film. One key effect: iodide likes to stick to certain substrates and can thereby kick out the bromide close to the interface. pubs.acs.org/doi/full/10....

On my way back from the MRS2025 Spring Meeting in Seattle and feeling grateful for a week full of interesting science and so many lovely conversations. I highly appreciate this vibrant and welcoming community. Until next time!

Great discussions, inspiring talks, and a fantastic atmosphere at Quantsol 2025 in Rauris ☺️ Such a great opportunity to connect, learn, and exchange ideas. Already looking forward to the next edition 🏔️

It’s always a pleasure to attend the DPG meeting, especially in Regensburg. So many nice reunions with old friends ☺️ and also new connections!

Its fun to dress up for a PhD defense! 🎓Thanks to Shuxia Tao for the invitation - an honor to be part of this special occasion. Congrats to Mike Pols, he has proven to be an excellent scientist!

I’m excited to announce that I’ve started my new role as Professor at the University of Wuppertal (@uni-wuppertal.bsky.social) this month! Through the Heisenberg Program of the DFG, I have been given the opportunity to establish my new Chair of Material and Surface Analysis.

How can photoelectron spectroscopy help us understand how molecules grow and interact with metal surfaces? Our latest publication explores the behavior of dipolar merocyanine molecules on metals, revealing insights into charge transfer, molecular orientation, and film growth. #OrganicSemiconductors

Greetings from the snowy Black Forrest. I hope everyone is enjoying their well-deserved time off 😊

It’s always a pleasure to see former and current group members come together! This year’s reunion at the Christmas market was another wonderful opportunity to reconnect, share memories, and celebrate the spirit of the season. Let’s see what exciting new changes are coming next year 😊
