#PhotoPero23 - Photophysics of halide perovskites and related materials – from bulk to nano

Halide perovskites have demonstrated remarkable performance in optoelectronic applications like light-emitting diodes and solar cells. Yet the detailed photophysics underlying their exceptional properties is far from fully understood.

This symposium aims to bring together the international science community to discuss the latest advances in the photophysics of bulk and nano-scale halide perovskites and related emerging materials. We will discuss the influence of chemical composition, dimensionality, defects, and structural distortions including chirality on the light-matter interactions on various timescales, based on both experimental and computational insights. Together, we will explore what is special about this material class, what currently limits their application and how to overcome them to break existing efficiency records in currently employed devices like solar cells & displays on the one hand, and to enable new functionalities on the other, for example for detectors or quantum light sources.
