Multi-fidelity Machine Learning Interatomic Potentials for Charged Point Defects
Xinwei Wang, Irea Mosquera-Lois, Aron Walsh
Machine learning interatomic potentials (MLIPs) can now reproduce the energy, forces and stresses of bulk materials with high accuracy compared to first-principles calculations. Th…
Breaking the 800 mV open-circuit voltage barrier in antimony sulfide photovoltaics
Jiacheng Zhou, Xinwei Wang, Tianle Shi +6
Sb2S3 is a promising material for low-toxicity, high-stability next-generation photovoltaics. Despite high optical limits in efficiency, progress in improving its device performanc…
Sulfur Vacancies Limit the Open-circuit Voltage of Sb2S3 Solar Cells
Xinwei Wang, Seán R. Kavanagh, Aron Walsh
Antimony sulfide (Sb2S3) is a promising candidate as an absorber layer for single-junction solar cells and the top subcell in tandem solar cells. However, the power conversion effi…
Upper efficiency limit of Sb2Se3 solar cells
Xinwei Wang, Seán R. Kavanagh, David O. Scanlon +1
Antimony selenide (Sb2Se3) is at the forefront of an emerging class of sustainable photovoltaic materials. Despite notable developments over the past decade, the light-to-electrici…
