Proceedings of Online Meetup - Beyond Lead Halide Perovskites: Syntheses and Applications of Metal Halide Semiconductors (MABP)
Publication date: 23rd April 2020
In this online seminar, we want to discuss state of the art metal halides, beyond those of the traditional lead halide perovskites This includes double perovskites (A2BCX6), vacancy ordered perovskites (like A3B2X9 and A2BX6), lower dimensional metal halides and metal chalcohalides. We will address the current challenges of making these materials, their interesting properties, like self-trapped exciton (STE) emissions, and their use in applications such as lead free metal halide based solar cells. We will also discuss how new chemistry can lead to the discovery of new metal halide structures with different properties to those that are exhibited in traditional lead halide perovskites. Finally, we will address how density-functional theory (DFT) calculations can help us to understand the luminescent properties and defects in these materials, which, in turn can provide a better passivation of defects.
