Organic-inorganic lead halide perovskites (including 2D hybrid perovskites) show great promise in optoelectronic applications such as light-emitting diodes and solar energy conversion. However, the poor stability and toxicity of lead halide perovskites severely limit their large-scale applications. In this talk, I am going to discuss our recent research progress on the high-throughput design of lead-free hybrid halide semiconductors with robust materials stability and desired material properties even beyond perovskites, as well as the new findings of germanium-based 2D hybrid perovskites inspired from the high-throughput screening results. Our work demonstrates a new avenue to design novel organic-inorganic functional materials by exploring a great variety of prototype structures. It is important to highlight that this approach is transformative to the discovery of other types of functional materials.
