ISOS 16: Where the Future of PV Stability Is Being Written

News08-09-2025

In the fast-evolving world of photovoltaics, stability is the new frontier. This September, ISOS 16 (International Summit on Organic and Hybrid Photovoltaics Stability) brings that frontier into focus at Thor Park, the heart of Europe’s renewable energy innovation. For three days, a diverse international community of researchers, industry leaders, journal editors, and protocol developers will gather at EnergyVille to tackle one question: how do we move thin-film photovoltaics from promise to product?

Seats are still available. First come, first connected!

Join us on 29 September – 1 October 2025 at Thor Central, Genk, Belgium

ISOS 16 creates a space where you feel part of the solution

“We’re no longer racing just for higher efficiency,” explains Tom Aernouts, thin-film PV lead at imec and co-host of ISOS 16. “Now, the challenge is to prove long-term reliability. If perovskite modules are to reach market maturity, they must survive for 20 to 25 years. That’s exactly what ISOS is about: understanding and building that stability.”

ISOS has a 20-year legacy of leading the conversation on photovoltaic reliability. This edition reflects a pivotal shift – from lab breakthroughs to marketable durability – and offers a first look at some of the most stable devices worldwide, through the inaugural ISOS Stability Competition, which aims to identify state-of-the-art tandem and single-junction devices based on their endurance against performance degradation under one-sun illumination at a constant temperature of up to 85°C. 

“We’ve designed ISOS 16 to foster open dialogue. That’s where real insight happens.” – Aranzazu Aguirre

“It’s not just another conference,” adds Aranzazu Aguirre, lead organiser and perovskite reliability lead at imec/EnergyVille. “We’ve designed ISOS 16 to foster open dialogue through roundtables, informal discussions, and walking dinners. That’s where real insight happens. It’s not about one-way presentations. It’s about co-creating knowledge.”

Don’t miss the conversations that will shape the next generation of solar technology.

What can you expect from this edition of ISOS?

  • Top-tier keynotes from names like Christophe Brabec, Monica Lira Cantu, and Morten Madsen.
  • Roundtable discussions designed for candid exchange on the big questions: standardisation, durability, upscaling.
  • Awards for best student talks and posters, co-sponsored by respected journals.
  • Announcement stability competition winners: be there when the winners of the world’s most robust devices are announced at ISOS for the first time.
  • Lab tours of EnergyVille’s large-area perovskite module production line. EnergyVille hosts one of Europe’s most advanced setups for thin-film PV stability research. “It’s a unique facility in Europe,” according to Aguirre.
  • Located in Thor Park in Genk, a growing European hub for integrated energy research. 

We can proudly say that EnergyVille is home to one of Europe’s most advanced setups for thin-film PV stability research,” says Aernouts. “And it’s all integrated into a larger ecosystem of sustainable energy. That’s what makes this location so special.”

ISOS 16 is small enough to be personal, international enough to be impactful.

Expect a compact, curated crowd from young scientists to seasoned industry veterans.

“Some participants have been part of ISOS for two decades. It feels like a reunion of minds.” – Aranzazu Aguirre

Networking extends beyond the agenda: a walking dinner and poster session will keep conversations flowing into the evening. A PhD school follows the main summit on 2 October, giving early-career researchers a chance to deepen their knowledge through expert-led lectures. Learn more about this follow-up event

Join the conversation

If your work touches perovskites, organic PV, or photovoltaic reliability, ISOS 16 is the moment to join the global conversation.

“You don’t just attend ISOS,” says Aernouts. “You help define what comes next.”
