报告题目：Navigate the Chemical Space of Hybrid Perovskites: From Inverse Design to Optoelectronic Applications

报告简介：As an emerging class of light-responsive semiconductors, hybrid organo-metal perovskites seamlessly marry the characteristics of organic and inorganic materials, offering a new fertile playground to explore light-matter interaction. They have been scrutinized by material scientists for over a century, but the past decade has seen a surge in interest due to their remarkable photovoltaic performance. The hybrid characteristics and the strong correlation of composition/structure/function in these frontier materials bring new opportunities and challenges. Here, I will highlight our latest efforts to adapt machine-learning and high-throughput approaches to navigate the vast chemical space of organic cations in hybrid perovskites. The inverse-design method accelerates the discovery of new materials, achieving precise control of the energy band structure of two-dimensional hybrid perovskites. These insights on the intricate interactions between organic molecules and inorganic framework of hybrid perovskites guide the experimental efforts on improving the performance of perovskite photovoltaics.
