The 18th International Conference on Hybrid and Organic Photovoltaics (HOPV26) will take place from May 18th to 20th at the Uppsala Konsert&Kongress, in Uppsala, Sweden.

HOPV26 explore the cutting-edge advancements in hybrid and organic solar cells, including perovskite, organic, and other novel solar cells, as well as their integration into complementary photoelectrochemical systems. Building on the success of previous conferences, HOPV 2026 will gather scientists and engineers from around the world to discuss the latest developments in these areas. The event will feature renowned invited speakers who will cover a broad range of topics in morning plenary sessions, followed by afternoon parallel sessions. The conference will devote special attention to cross disciplinary discussions and knowledge exchange, highlighting the importance of advanced materials and emerging technologies in the solar energy field. It will also feature special sessions on energy policy and career development.

Key topics of the conference include material design in organic and hybrid photovoltaics, artificial intelligence and machine learning for energy technologies, advanced characterization techniques for new-generation photovoltaics, breaking efficiency limits, operational stability measurement and reporting, scale-up and commercialization of new-generation photovoltaics, emerging framework materials for energy conversion, multifunctional materials in energy conversion and beyond, emerging concepts in solar energy conversion (from optoionics to photoferroics), photoelectrochemical energy conversion, and energy policy and diplomacy. These topics will be addressed by experts in their respective fields, promoting comprehensive discussions and the exchange of ideas to further advance the field of solar energy and its applications. The combination of diverse topics and interdisciplinary approaches will ensure a fruitful and engaging conference experience for all participants.

The conference took place in the Uppsala Konsert&Kongress, a venue located in the heart of Uppsala, Sweden.
