HL 1: Focus Session: When theory meets experiment: Hybrid halide perovskites for applications beyond solar

Monday, September 27, 2021, 10:00–12:45, H4

Hybrid halide perovskites are by now well-established solar absorber and emitter materials, with power conversion efficiencies of single-cell devices exceeding 20 percent. We have observed - with notable exceptions - a widening gap between experimental and theoretical efforts in the literature on halide perovskites. Further, a large fraction of the literature focuses on properties relevant for optoelectronic applications, while we envision a much wider scope for these materials, e.g in spintronic and electrochemical applications. The purpose of this focus session is to provide a platform for theorists and experimentalists working in this field, to interact, present state-of-the-art methods, and exchange their ideas on future directions for this technologically relevant class of materials beyond the current focus on optoelectronics.

Organizers: Linn Leppert (University of Twente) and Felix Dreschler (TU München)
