CheMatAgent: Enhancing LLMs for Chemistry and Materials Science through Tree-Search Based Tool Learning

Mengsong Wu, Yafei Wang, Yidong Ming, Y. An et autres

Large language models (LLMs) have recently demonstrated promising capabilities in chemistry tasks while still facing challenges due to outdated pretraining knowledge and the difficulty of incorporating specialized chemical expertise. To address these issues, we propose an LLM-based agent that synergistically integrates 137 …

Spontaneous bifacial capping of perovskite film for efficient and mechanically stable flexible solar cell

Junjun Jin, Zhenkun Zhu, Yidong Ming, Yuan Zhou et autres

Flexible perovskite solar cells (F-PSCs) are appealing for their flexibility and high power-to-weight ratios. However, the fragile grain boundaries (GBs) in perovskite films can lead to stress and strain cracks under bending conditions, limiting the performance and stability of F-PSCs. Herein, we …
