报告题目：Design and Properties of Hybrid Perovskites: Man vs. Machine

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 studied by materials scientists for more than a century, but in the past decade, perovskites have attracted a new wave of intense interest due to their extraordinary photovoltaic properties. The hybrid characteristics of organometallic perovskites bring a unique combination of physical properties, while also endowing the material with unprecedented complexity. The strong correlation of composition/structure/function in these frontier materials exposes us to new challenges. Here, I will talk about our recent efforts to adapt both curiosity-driven and machine-learning approaches to confront these challenges. In one example, the dynamics of organic cations were found to determine the structural symmetry and glassy behavior, which led to our discovery of anomalous crystallographic phases over a wide temperature range in mixed-halide perovskites. As another example, I will discuss the use of high-throughput computing and machine learning to achieve precise control of the energy band structure to accelerate the discovery and design of new materials.
