The International Workshop on Vacuum Processed Perovskite Solar Cells, held this week at the Universitat de València, brought together some of the world’s leading researchers and representatives from industry to discuss the latest advancements in perovskite-based photovoltaics, one of the most promising technologies for the future of solar energy.

Perovskite solar cells have reached remarkable efficiencies of over 27%, and when combined with silicon, they exceed 34.9%, making them a key candidate to revolutionize the photovoltaic market. The workshop focused on solvent-free processing techniques that enable ecological manufacturing of perovskite absorber layers, an essential step toward the large-scale industrialization of this technology.

Throughout the sessions, international experts shared cutting-edge results and discussed strategies to accelerate the transition from laboratory research to industrial application. The event also provided a unique platform to foster collaborations between academia and industry in the field of next-generation solar technologies.

In addition to the scientific presentations, participants visited the facilities of the Molecular Optoelectronic Devices (MOED) Team at the Institute of Molecular Science (ICMol), led by Professor Henk J. Bolink. During the visit, attendees explored the laboratory’s advanced scientific equipment and met the research team working on cutting-edge topics in dry processed perovskite-based photovoltaics funded by the Horizon Europe project “VALHALLA”.

The workshop featured presentations from prominent scientists, including Beom-Soo Kim (Korea Research Institute of Chemical Technology), Yi Hou (National University of Singapore), Monica Morales (University of Twente), Stefaan De Wolf (King Abdullah University of Science and Technology), Michael Johnston (University of Oxford) and Henk J. Bolink (Universitat de València), among others.

Industry participation was also a key highlight, with contributions from companies such as First Solar, Von Ardenne, Oxford PV, Singulus Technologies, Hanwha Qcells, Euris SAS, LKChen, Singfilm Solar, Korea Kiyon, Everlight, Microquanta and Swift Solar, who showcased their efforts in scaling up perovskite-based technologies for real-world applications.

The workshop was organized by Annalisa Bruno (Nanyang Technological University, Singapore), Monica Morales (University of Twente, The Netherlands), Adriana Paracchino (CSEM, Switzerland), Beom-Soo Kim (Korea Research Institute of Chemical Technology, South Korea), and Henk J. Bolink (Universitat de València, Spain).
