nanoGe is eager to promote the organization of online seminars. Do you have a topic? It's very easy to lauch a meetup! Just describe the topic, decide a few speakers, and fill the form.

Most important: We wish to encourage participation of both junior and senior researchers, please propose interesting research directions

The Online seminar Beyond lead halide perovskites: syntheses and applications of metal halide semiconductors took place on Thursday 23 April 2020.

Contents

The Beyond Halide Perovskites was a short online seminar that aims to promote an exchange of knowledge and discussions about the most recent research on metal halide materials, beyond lead halide perovskites. This seminar focused on the synthesis, properties, and applications of these new metal halides, covering both experimental and theoretical work, and will discuss the results on the nanoscale and bulk.

Over the last two decades, lead halide perovskites have been identified as one of the most promising materials in photovoltaic and light-emitting devices. This has also led to the search and discovery of other metal halide materials, mainly driven the toxicity and stability problems of lead halide perovskites. Consequently, researchers have been quick to develop alternative metal halide structures like double and vacancy perovskites, lower dimensional metal halides, as well as more complex metal chalcohalides.

In this online seminar, we wanted 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 also discussed 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 addressed 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.
