Halocell Chief Scientist David Pham has collaborated with QUT researchers on recently published paper "Ecofriendly Solution Processing of Perovskite Solar Cells Using Water.” The paper was published in The Journal of Physical Chemistry Letters and explores the use of water as a perovskite solvent as an environmentally friendly alternative to traditional solvents, aligning with the global drive for sustainable renewable energy technologies. The article provides an overview of research in the area of PSC fabrication using water as a solvent, highlighting key advancements in the synthesis process, and delves into the kinetics of crystallization and the physical–chemical transformations of perovskite materials in water-based solution processing. Key challenges of the scalability of water-based solution processing for PSC fabrication are discussed. The Perspective sheds light on the broader potential for enhancing the ecofriendliness of perovskite solar cell technologies.
