<dcterms:abstract xml:lang="fr">Face aux enjeux liés au changement climatique et à l’épuisement des ressources fossiles, le développement de sources d’énergie renouvelable constitue une priorité. Les cellules photovoltaïques organiques (OPVs) représentent une alternative prometteuse grâce à leur flexibilité, leur légèreté et leur potentiel de fabrication à faible coût. Toutefois, leur rendement et leur stabilité restent des défis majeurs pour une adoption à grande échelle. Dans ce contexte, les avancées en intelligence artificielle (IA), notamment en apprentissage automatique (machine learning (ML)) et en apprentissage profond (deep learning (DL)), offrent des perspectives inédites pour la découverte et l’optimisation de matériaux organique des OPVs. Cette thèse explore l’application de techniques d’IA à la prédiction des performances des OPVs à partir des structures chimiques des matériaux organique (paires Donneur/Accepteur). Nous nous sommes concentrés sur les cellules constituées d’un donneur (ou D) et d’un accepteur (ou A) d’électrons en hétérojonction volumique (Bulk Heterojunction, BHJ). Trois contributions principales sont proposées : La prédiction des performances des OPVs à partir de descripteurs moléculaires extraits des représentations SMILES des matériaux donneurs et accepteurs via l’apprentissage automatique, l'entraînement de modèle de machine learning sur deux bases de données : l’une contenant uniquement des accepteurs de type fullerène (FA) et l’autre incluant également d’autres non dérivés de fullerène (NFA) et enfin le développement d’une approche d’apprentissage profond exploitant les images 2D des structures chimiques des paires donneur/NFA. Ces travaux illustrent le potentiel de l’IA pour accélérer la conception rationnelle de matériaux performants, contribuant ainsi au progrès des technologies solaires organiques durables.</dcterms:abstract>
<dcterms:abstract xml:lang="en">Faced with the challenges of climate change and the depletion of fossil fuels, the development of renewable energy sources is a priority. Organic photovoltaic cells (OPVs) represent a promising alternative thanks to their flexibility, light weight and low-cost manufacturing potential. However, their efficiency and stability remain major challenges for large-scale adoption. In this context, advances in artificial intelligence (AI), particularly machine learning (ML) and deep learning (DL), offer novel perspectives for the discovery and optimization of organic materials for OPVs. This thesis explores the application of AI techniques to the prediction of OPV performance based on the chemical structures of organic materials (Donor/Acceptor pairs). We focus on cells consisting of a Bulk Heterojunction (BHJ) of electron donor (or D) and electron acceptor (or A) molecules. Three main contributions are proposed: prediction of OPV performance from molecular descriptors extracted from SMILES representations of donor and acceptor materials via machine learning, machine learning model training on two databases: one containing only fullerene-type acceptors (FA) and the other also including other non-fullerene derivatives (NFA) and finally the development of a deep learning approach exploiting 2D images of the chemical structures of donor/NFA pairs. This work illustrates the potential of AI to accelerate the rational design of high-performance materials, thus contributing to the progress of sustainable organic solar technologies.</dcterms:abstract>
