“…While the underlying problem is similar to before, i.e., finding suitable materials from large configuration spaces, here the constraints on suitability are based on electrical properties such as the band gap or the photoelectric conversion coefficient (PCE). ML has been employed in a number of studies [240], [241], [242], [243], [244], [245], [246], [247], [248], [249], [250], [251], [252], [253], [254], [236], [255], [256], [257], [258], [259], [260], [261], [262], [263], [264], [265], [266], [267].…”
