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. By fostering collaboration and knowledge exchange, PeroPRINT aims to catalyze innovation in the sustainable development of high-performance perovskite-based devices.
