Interface passivation using an ammonium salt can effectively improve the power conversion efficiency (PCE) of perovskite solar cells (PSCs). Despite significant PCE improvement achieved in previous studies, selection criteria for salts are not fully understood. Here we apply a machine-learning (ML) method to investigate relationship between molecular features and PSCs. We establish ML model experimental data set 19 predict after passivation. Three (hydrogen bond donor, hydrogen atom, octane–water partition coefficient) identified as most important selecting The is further used screen from pool 112 PubChem database. FAMACs FAMA-based PSCs fabricated with model-recommended (2-phenylpropane-1-aminium iodide) achieve PCEs 22.36% 24.47%, respectively.

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(12), С. 8198 - 8205

Опубликована: Март 13, 2024

Dion–Jacobson (DJ) phase 2D perovskites with various aromatic diammonium cations, potentially possessing high stability, have been developed for optoelectronics. However, their stability does not meet initial expectations, and some of them even easily degrade into lower-dimensional structures. Underlying the mechanism dimensional reduction these DJ remains elusive. Herein, we report that π–π stacking intensity between cations determines structural variation by investigating nine benzene diammoniums (BDAs)-derived low-dimensional perovskites. The BDAs without intermolecular form stable perovskites, while those showing strong tend to generate 1D 0D architectures. Furthermore, highly relies on molecular symmetry electrostatic potential BDAs; namely, asymmetry small dipole moment facilitate alleviating stacking, leading formation vice versa. Our findings establish relationship structure−π–π interaction–perovskite dimensionality, which can guide design manipulation perovskite dimensionality optoelectronic applications.
