Abstract:As one of the most studied materials, perovskites exhibit a wealth of superior properties that lead to diverse applications. Computational prediction of novel stable perovskite structures has big potential in the discovery of new materials for solar panels, superconductors, thermal electric, and catalytic materials, etc. By addressing one of the key obstacles of machine learning based materials discovery, the lack of sufficient training data, this paper proposes a transfer learning based approach that exploits… Show more
“…In addition to E hull , the formation energy of compounds could also be used to evaluate the formability and stability of perovskite. Li et al 63 proposed a transfer learning strategy to evaluate the stability of the ABX 3 inorganic perovskites. First, an ML transfer learning model was constructed by taking the formation energies of 570 perovskites as the target variable and the physics-informed structural and elemental parameters of perovskites as descriptors.…”

The development of materials is one of the driving forces to accelerate modern scientific progress and technological innovation. Machine learning (ML) technology is rapidly developed in many fields and opening blueprints for the discovery and rational design of materials. In this review, we retrospected the latest applications of ML in assisting perovskites discovery. First, the development tendency of ML in perovskite materials publications in recent years was organized and analyzed. Second, the workflow of ML in perovskites discovery was introduced. Then the applications of ML in various properties of inorganic perovskites, hybrid organic–inorganic perovskites and double perovskites were briefly reviewed. In the end, we put forward suggestions on the future development prospects of ML in the field of perovskite materials.

“…Temperature-dependent structural phase transitions are very common in halide perovskites. 5–7 Different perovskites have been found in multiple crystallographic phases at different temperatures and the common phases are cubic, tetragonal, and orthorhombic. 6,7 However, the cubic phase is the most common phase among the perovskite materials.…”
This work summarizes that RbSnX3 (X = Cl, Br, I) exhibits remarkable ductility and absorption in the ultraviolet (UV) region of the electromagnetic spectrum compared to those of CsBX3 (B = Ge, Sn, Pb; X = Cl, Br, I) metal halide perovskites.
“…An exemplar of the CBFV method is the Magpie [1] descriptor. This domain-derived approach (CBFV) has been successfully employed in materials informatics studies for years [2][3][4][5][6][7]. Not only has it been successful, but the information it contains is also human-readable, allowing for physically interpretable results.…”
New methods for describing materials as vectors in order to predict their properties using machine learning are common in the field of material informatics. However, little is known about the comparative efficacy of these methods. This work sets out to make clear which featurization methods should be used across various circumstances. Our findings include, surprisingly, that simple one-hot encoding of elements can be as effective as traditional and new descriptors when using large amounts of data. However, in the absence of large datasets or data that is not fully representative we show that domain knowledge offers advantages in predictive ability.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
