The broad materials library of halide perovskites and their versatility have made this class of semiconductors exciting for a wide range of optoelectronic applications. Much of this success is based on the unique tunability of composition, dimensionality, optical and electronic properties as well as their defect tolerance. A better understanding of their properties and synthesis mechanisms is, however, needed for further progress and development. Here, advanced characterization methods and the ever-evolving theoretical framework help to observe and better understand these properties, which need to be addressed over several length and time scales.

This symposium aims to bring the community together to present these recent advances in our fundamental understanding of halide perovskites and discuss how theory as well as spectroscopy and microscopy tools can be applied to increase our knowledge base. We will explore new materials chemistries, optical and electronic behavior, the role of dimensionality, crystallization mechanisms in solution- and vapor-processing and defect dynamics. We invite contributions from a diverse set of speakers from a variety of scientific backgrounds to emphasize the interdisciplinary nature of the field that has been foundational to its success.

With the rapid progress in perovskite solar cells, research on perovskite optoelectronic devices, including light-emitting diodes, photodetectors, and lasers, has also seen remarkable growth. This surge is primarily driven by the easy tunability of optical bandgaps in halide perovskite materials. These materials offer a broad color spectrum from ultraviolet to near-infrared, coupled with high luminescence yields and exceptional color purity. The development of innovative chemical routes for synthesizing perovskite layers has led to a solid foundation for producing optoelectronic devices. While spin coating remains the go-to method for achieving high performance in laboratory, industrial applications demand scalable techniques that enable mass production, large-area deposition, and spatial resolution. Recent European projects proposed printing technologies as a more sustainable approach to fabricating perovskite devices.

Therefore, this symposium serves as a platform to bring together the scientific community and industry stakeholders to evaluate the potential of various printed electronics techniques—such as inkjet , screen printing, slot-die , blade-coating and gravure —for advancing perovskite optoelectronic and electronic devices. A special focus will be given to environmentally friendly approaches, alongside emerging studies that integrate machine learning to optimize printing processes.
