Abstract

This study aimed to identify donor molecules that enhance the J_SC in fullerene-type organic thin-film solar cells using materials informatics. After performing principal component analysis and Random Forest for feature selection, LASSO and Ridge regressions and SVR were developed. A genetic algorithm generated 250 new donor molecules, and SVR predicted that (i) 4H-cyclopentadithiophene, (ii) fluorine-containing structures, and (iii) C = O groups adjacent to thiophenes improve the J_SC.

期刊介绍： Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review. Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage. Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
