"By varying multiple film deposition parameters according to the suggestions of constrained Bayesian optimization, we found that the combination of substrate temperature during film deposition and the flow rate of the precursor gas SiH4 is crucial for achieving strong ability to suppress carrier recombination," says Prof. Ohdaira. "Constrained Bayesian optimization, thus, provides not only optimal deposition conditions but also scientific knowledge."

Together, the findings of this study showcase the potential of constrained BO for developing not just high-performance solar cells but all sorts of devices. Prof. Ohdaira concludes, "The proposed approach should be applicable across a wide range of fields for the practical optimization of complicated material processes, including film deposition, which is fundamental in the manufacture of most electronic devices."
