Fluxim at PSCO 2026
With PSCO taking place in our home country this year, the journey was a little simpler than usual. If you didn’t make it to Lausanne, here’s what stood out to us...
We came back from PSCO with a lot of notes, as always. Some we’ll discuss in more detail; others that seemed relevant at the time will probably be saved for another day.
There are far too many discussion points for a LinkedIn post — or even a blog — but if we had to sum up our impression in one sentence:
The perovskite community feels more mature, more reflective, and more focused on the questions that really matter.
What encouraged us most was the noticeable shift away from record efficiencies alone and towards stability, reproducibility, statistics and realistic testing conditions.
One comment from Henry at the conference dinner captured this particularly well: remember to report stability for more than one cell (we have an instrument for just this purpose ;-). hashtag
Throughout the conference, there was a clear awareness that single-device results are no longer enough. Understanding stability under different voltages, light intensities, wavelengths and temperatures is becoming increasingly important.
There also seemed to be less emphasis on simply advertising the latest efficiency number. Instead, much of the discussion centred on two broad questions: What is fundamentally happening inside these devices? And how do we make them reliably stable?
These topics may be less spectacular than another headline efficiency, but they are exactly what will determine whether the technology can move forward with confidence.
There are still plenty of open questions — from clearer benchmarking and testing protocols to the surprisingly limited presence of simulation and modelling. But that is also what made the conference interesting: the field is asking harder and increasingly practical questions.
And those questions are expanding beyond terrestrial PV. From tandems and material availability to AI-driven experimentation and perovskites for space applications, the range of potential applications continues to grow.
We left Lausanne with a positive feeling. Perovskites are no longer just an exciting research topic; they are becoming a field increasingly serious about reliability, transparency and real-world — and even off-world — relevance.
Thanks to the organizing committees for another strong scientific programme, and to everyone who stopped by the Fluxim booth or joined the discussions.
See you at PSCO 2027.
