Thin film processes are ubiquitous in photovoltaics research and are increasingly incorporated into high-throughput experimentation (HTE) equipment. However, the lack of rapid yet accurate thickness measurements limits the throughputs of HTE. This study demonstrates rapid yet accurate thin-film thickness
extraction by leveraging machine learning (ML) in combination with a rapid non-destructive optical measurement (UV-Vis). We achieve 86.1% accuracy of thickness prediction within 10-
percentage-error bounds on simulated data.
