The Donor molecule materials for fullerene-based organic solar cells were categorized into training and test datasets, and machine learning was conducted using leave-one-out cross-validation (LOOCV) with donor JSC as the objective variable to generate donor molecules with high JSC values. The JSC was calculated using a machine learning method. The donor molecule structure that exhibited the highest contribution to JSC comprised three five-membered ring structures with thiophenes at both termini of the unit structure and a partially fluorinated molecular backbone.
