The 36th Conference on Quantum Solar Energy Conversion - QUANTSOL 2026 - in Rauris, Austria was an absolute highlight. Amazing place and people, highly recommend!

What a fantastic week in Costa Rica, as the International Conference on Energy Materials came to an end. A massive thank you to the organizers Monica Morales-Masis, Marina Freitag, Pablo P. Boix & Filippo de Angelis for the invitation to see a country that runs essentially 100% on #renewable

Check out our latest in @acs.org ACS Energy Letters: Damon explores how #chirality may impact singlet fission and triplet fusion in molecular semiconductors as a new twist for efficient photon management, boosting performance of solarcells, displays and more. #OpenAccess pubs.acs.org/doi/10.1021/...

The Impact of Chirality on Singlet Fission and Triplet Fusion: A Molecular Twist for Photon Management

Chirality has recently emerged as a new means to profoundly impact the properties of organic semiconductors for spin-optoelectronic applications. Yet, a clear mechanistic understanding of chiral structure–property relationships remains absent to date, particularly for photon interconversion processes such as singlet exciton fission and triplet fusion. In this perspective, we highlight recent work that investigates chiral structures for these processes. We discuss the various ways in which chirality can impact such conversion processes and suggest ways to leverage it to improve photon management for both energy applications and quantum information science.

Group social - Valais Carnival meets Bowling! We had a blast and I learned that a bowing lane in French is a “piste” just like for skiing;) #teambuilding #workhardplayhard

#Outreach - We had a blast hosting 3 high schoolers for the Swiss Study Week in Materials Science & Chemistry, organized together with Schweizer Jugend Forscht! They made some beautifully emissive quantum dots in the lab and presented their results to the general public. #EPFL

Impressions from an amazing faculty meeting invited by the Swiss Academy of Sciences on the beautiful Griesalp❄️

Thanks for letting us join for a small part in this! Check out these beautiful cages and their host-guest energy transfer !:) 👉
