Symposium EN05-Halide Perovskites—From Fundamentals to Applications

Halide perovskites are now a well-established class of functional materials with promising applications in energy-efficient devices, 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 materials’ science and engineering aspects related to the modeling, fabrication, characterization, processing, and stability of halide perovskites. The further advancement of devices relies on our full 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.

Topics will include:

Stability and degradation mechanisms in hybrid perovskites
Advances in fabrication methods
Data science applied to halide perovskites
Excitons, phonons, polarons, and carrier-phonon coupling
Role of defects, impurity doping, and mobile ions, interfaces and surfaces
Low dimensional systems
Sn-Pb alternatives
Spectroscopy and non-linear optical behavior
Micro- and nano-scale imaging methods
Dynamic properties and methods to interrogate them
Theory and modeling
Applications: photovoltaics, LEDs, photodetectors, transistors and thermoelectric devices
