At the University of Sheffield, researchers have turned a long-stubborn manufacturing challenge into an occasion for deeper understanding — applying machine learning to the delicate art of depositing thin films onto the substrates that power solar cells, batteries, and fuel cells. Where trial and error once demanded years of accumulated intuition, a surrogate model now reveals which variables truly govern the process, and why. This is not merely faster optimization; it is a shift in how human knowledge about complex systems is built and transferred.
