Emerging Optoelectronics for a Sustainable Future

Datum: 2026-04-28–2026-04-29

Lokal: Beijer Hall

Adress: The Royal Swedish Academy Of Sciences, Lilla Frescativägen 4 A, Stockholm

Sista anmälningsdatum: 2026-03-29

A Royal Swedish Academy of Sciences and Marcus Wallenberg Symposium. The symposium is supported by the Tage Erlander Prize.

Emerging optoelectronics, exemplified by devices based on organic semiconductors, semiconducting perovskites, and colloidal nanocrystals, are at the frontier of physics, chemistry, and materials science. They play a key role in developing next-generation technologies that promise to revolutionize industries such as renewable energy and consumer electronics. For example, emerging optoelectronic materials are gaining significant attention for applications in next-generation photovoltaics, which are crucial for harnessing sunlight more efficiently and cost-effectively. Additionally, these materials hold great promise for energy-efficient displays, which are in high demand in industries ranging from smartphones and televisions to virtual reality systems. They are also enabling new-generation detectors, such as photodetectors and X-ray detectors, which are crucial for applications in consumer electronics, health diagnostics, and security checks.

These emerging semiconductors are often more flexible and lightweight, making them ideal for new applications such as wearable electronics, flexible displays, and foldable solar cells. Furthermore, many of these materials, especially organic semiconductors, are made from abundant and environmentally friendly elements, contributing to a lower environmental impact throughout their lifecycle.

Through this symposium, we aim to inspire new ideas and strategies to tackle critical challenges in advancing sustainable optoelectronic technologies, such as next-generation photovoltaics, cost-effective displays, and environmentally friendly detectors. We also aim to create a dynamic platform for networking and professional development, enhancing opportunities for the engagement of Swedish researchers with global experts and industry leaders.

Registration
Registration is required. Participants travelling to Stockholm for the symposium are expected to arrange and pay for their own travel and hotel reservations. Lunch and coffee during the symposium will be covered for all registered participants.

Poster
Please let us know if you would like to present a poster at the symposium. It is possible to submit a short abstract when you register. All abstracts will be reviewed and those accepted to bring a poster will be notified by the organiser. Deadline for abstracts is 29 March.
