Solution chemistry is the cornerstone of scalable, low-cost, and sustainable fabrication of thin-film photovoltaic (PV) and functional materials, enabling high-efficiency perovskite, organic, quantum-dot, kesterite, chalcogenide, and hybrid solar cells. This symposium will highlight fundamental advances in solution-based film deposition, precursor design, solvent engineering, additive strategies, crystallisation kinetics, and in-situ/operando characterisation that control film morphology, defect chemistry, interfaces, and device performance.
Emphasis will be placed on bridging lab-scale insights with industrially relevant processes — such as slot-die coating, blade coating, inkjet printing, and spray deposition — while integrating data-driven and automation approaches, including artificial intelligence, machine learning, and high-throughput experimentation. The symposium will critically address key challenges, including long-term operational stability, adoption of green and sustainable solvents, reliable upscaling to large-area modules, seamless integration into multijunction and tandem architectures, and the pressing issue of batch-to-batch and lab-to-lab reproducibility.
By uniting chemists, materials scientists, and device engineers, the symposium aims to accelerate the development of next-generation, environmentally benign PV technologies that meet the demands of sustainable energy production. Contributions on both fundamental solution-phase mechanisms and applied device-level outcomes are warmly invited.

Silvia Colella is a researcher at the National research council, CNR-NANOTEC, in Bari, Italy. She received her PhD in “Nanoscience” at National Nanotechnology Laboratory in Lecce (Italy), in 2010. She has been visiting student in the group of professor Luisa De Cola at the Westfälische Wilhelms-Universität of Münster (Germany), where she dealt with the synthesis and photophysical characterization of electroluminescent metal complexes. In 2010 she joined BASF – The Chemical Company (Strasbourg) with a Marie Curie fellowship as experienced researcher in the frame of the EU project ITN SUPERIOR, working on Dye Sensitized Solar Cells. She continued as post-doc researcher at the Institut de science et ingénierie supramoléculaires (ISIS) in Strasbourg, France. In 2012 she started her independent research in Lecce (Italy) at the University of Salento in collaboration with CNR-NANOTEC, the team focused on the conception and optoelectronic characterization of innovative optoelectronic devices based on hybrid halide perovskites. Many high impact publication were produced in this time interval, among them one of the first report in halide perovskite for PV exploitation (Colella et al, Chemistry of Materials, 2013 25, 4613-4618).
Silvia Colella is author of >70 peer-reviewed publications in renowned international journals (including Energy and Environmental Science, Advanced Materials, ACS Energy Letters).

Juanita HidalgoDr Luis Lanzetta is a Postdoctoral Fellow at King Abdullah University of Science and Technology (KAUST, KSA). He obtained his PhD in Chemistry at Imperial College London (UK) in 2020, where he focused on developing eco-friendly, tin-based perovskites for photovoltaic and light-emitting applications. His research focuses on next-generation materials for energy harvesting. Specifically, his expertise lies in the chemical degradation and stabilisation mechanisms of halide perovskite solar cells, aiming to provide design rules towards more efficient and stable technologies. He is additionally interested in molecular doping approaches for narrow-bandgap perovskites, as well as the spectroscopic and surface characterisation of this class of materials.
