Abstract
The energy crisis has gradually been reflected in all aspects. It is urgent to develop efficient and clean new energy to reduce the dependence on fossil energy. As a kind of material which can directly convert solar energy or other light energy into electric energy, organic photovoltaic material is becoming a kind of low-carbon energy material with great application prospect. While machine learning can improve the efficiency of material design in the search for new high performance organic photovoltaic materials, its predictive power is severely limited by developing and selecting descriptors. An end-to-end deep learning model has been constructed to predict the photoelectric conversion efficiency of organic photovoltaic materials using algorithms such as cyclic neural networks, convolutional neural networks, and graph neural networks. The constructed model can directly extract the structural information of compounds from Simplified Molecular Input Line Entry System (SMILES) symbols, molecular images and molecular graph networks, without the need to manually develop and select descriptors. Our model can not only accurately predict the photoelectric conversion efficiency of organic photovoltaic materials (the determination coefficients of the optimal model and the test set prediction are both > 0.73) and can identify key structural features that affect conversion efficiency. The research results can provide solutions for the design of new photovoltaic materials.
