Halide perovskites are now a well-established class of functional materials with promising device applications ranging from photovoltaics to LEDs and thermoelectrics. Specifically, in the last 15 years the scientific community has witnessed several breakthroughs in optoelectronics (e.g. near unity internal quantum yield, promising self-healing properties, long-lived charge carriers, etc.) as a direct consequence of a better understanding of the correlation between materials’ properties, processing, and device performance. This symposium will focus on both the materials’ science and engineering aspects related to the modeling, fabrication, characterization, processing, and stability of halide perovskites. The further advancement of devices relies on developing a detailed understanding of the fundamental physical and chemical processes that occur within these materials. Thus, the symposium welcomes presentations related to the implementation of automated experiments and the use of machine learning toward consistent fabrication of devices and to accelerate the understanding of materials properties/stability, respectively. Further, the realization of advanced characterization methods, including microscopy tools and time-dependent techniques are welcome to this discussion forum as they will enable us quantifying carrier-phonon coupling, ion motion, surface-limited chemical reactions, electrical transient responses, the effects of grain boundaries on device performance, among other phenomena.
