Mesoscopic structures and 3D charge injection mechanisms provide a viable route for the development of low-cost, high-performance photovoltaic devices based on all-wet processing. This symposium invites contributions on innovative research and practical challenges to boost the efficiency, stability and scalability of printable mesoscopic perovskite solar cells (p-MPSCs) from the perspectives of material innovation, structural design and device engineering. It will further explore core scientific and technical issues in mesoscopic scaffold modification, perovskite crystal growth regulation, interface defect passivation, and light-trapping structure design for p-MPSC photovoltaic systems. Related topics include low-temperature printable material formulation, mesoscopic network optimization, carrier separation and transmission enhancement, environmental stability improvement, spectral response optimization, and large-area module fabrication technology, aiming to promote the industrialization development of high-performance p-MPSC devices.

Professor of Physical Chemistry at the Ecole Polytechnique Fédérale de Lausanne (EPFL) Michael Graetzel, PhD, directs there the Laboratory of Photonics and Interfaces. He pioneered research on energy and electron transfer reactions in mesoscopic systems and their use to generate electricity and fuels from sunlight. He invented mesoscopic injection solar cells, one key embodiment of which is the dye-sensitized solar cell (DSC). DSCs are meanwhile commercially produced at the multi-MW-scale and created a number of new applications in particular as lightweight power supplies for portable electronic devices and in photovoltaic glazings. They engendered the field of perovskite solar cells (PSCs) that turned our to be the most exciting break-through in the recent history of photovoltaics. He received a number of prestigious awards, of which the most recent ones include the RusNANO Prize, the Zewail Prize in Molecular Science, the Global Energy Prize, the Millennium Technology Grand Prize, the Samson Prime Minister’s Prize for Innovation in Alternative Fuels, the Marcel Benoist Prize, the King Faisal International Science Prize, the Einstein World Award of Science and the Balzan Prize. He is a Fellow of several learned societies and holds eleven honorary doctor’s degrees from European and Asian Universities. According to the ISI-Web of Science, his over 1500 publications have received some 230’000 citations with an h-factor of 219 demonstrating the strong impact of his scientific work.
Prof. Hongwei Han is currently a Second-Class Professor and PhD Supervisor at the Wuhan National Laboratory for Optoelectronics, Huazhong University of Science and Technology. He has long been dedicated to pioneering research in optoelectronic materials and devices, with a core focus on mesoscopic optoelectronic materials and devices.
He pioneered the universal manufacturing platform technology for mesoscopic optoelectronic devices based on a triple-layer mesoporous architecture, established a multi-material compatible, cross-device technical framework, and proposed the 3D injection mechanism for oriented charge separation and transport in topologically interpenetrating networks. His work has solved the global challenge of fabricating high-performance large-area optoelectronic devices via an all-wet process, and the related technology has been named "Han Cells" or "Wuhan Cells" by the international academic community.
Prof. Han has published more than 200 papers in top international journals including Science, Nature Reviews Materials, Nature Energy, Nature Synthesis, Joule, Journal of the American Chemical Society, and Advanced Materials et al., with total citations exceeding 25,000 and a single paper cited over 3,500 times.
His achievements have won the First Prize of Hubei Natural Science Award. He was selected as an Expert with Special Government Allowance of the State Council (2023), Distinguished Professor of the Changjiang Scholars Program (2016), and Leading Talent in Scientific and Technological Innovation of the National Ten-Thousand Talents Program (2017) in China.
Lioz Etgar obtained his Ph.D. (2009) at the Technion–Israel Institute of Technology and completed post-doctoral research with Prof. Michael Grätzel at EPFL, Switzerland. In his post-doctoral research, he received a Marie Curie Fellowship and won the Wolf Prize for young scientists. Since 2012, he has been a senior lecturer in the Institute of Chemistry at the Hebrew University. On 2017 he received an Associate Professor position. Prof. Etgar was the first to demonstrate the possibility to work with the perovskite as light harvester and hole conductor in the solar cell which result in one of the pioneer publication in this field. Recently Prof. Etgar won the prestigious Krill prize by the Wolf foundation. Etgar’s research group focuses on the development of innovative solar cells. Prof. Etgar is researching new excitonic solar cells structures/architectures while designing and controlling the inorganic light harvester structure and properties to improve the photovoltaic parameters.
Lara Perrin is Associate Professor at University Savoie Mont Blanc (France) since 2006, in the GUIDE team (Genesis, Usage of Durable Interfaces for Energy) of the LEPMI laboratory (Laboratory of Electrochemistry and Physical chemistry of Materials and Interfaces). This team is part of the National Institute of Solar Energy and is located at Le Bourget du Lac. She is a specialist in the chemistry of materials with specific properties, and her work combines chemistry, physical chemistry and physics. Her current research activities are mainly focused on materials for energy (third generation solar cells: organic and perovskite, electric cables, fuel cells ...). Her work focuses on both the Genesis and the Sustainability of these different systems.
