Symposium EN08-Low-Dimensional Halide Perovskites—From Fundamentals to Applications

Hybrid perovskites are a remarkable class of materials that have found application in a range of optoelectronic devices, such as solar cells, light-emitting diodes, photodetectors, and displays. While research has predominantly focused on the study of 3D perovskites, recent efforts have been devoted to lower dimensional perovskites (LDP), such as 2D perovskites and perovskite quantum dots. LDP offer a range of advantages in device applications, most significantly, an enhancement in the device stability. In 3D/2D structures, synergistic interactions lead to a reduction in the charge trapping losses and favorable interfacial processes. However, the efficiencies of emerging technologies based on LDP still lag behind due to a lack of understanding of their physico-chemical properties, and how these change over time. In particular, 2D/3D perovskite structures are very interesting for high performance, stable opto-electronics, however the complex interfacial phenomena remain elusive.

This symposium seeks to highlight the recent progress made in addressing the current open questions regarding the fundamental properties of LDP and their application in opto-electronic devices with a special focus on: 1. advances in material design, emphasizing the importance of synthetic chemistry in tuning the material properties to obtain the desired functionality; 2. recent developments on the link between material processing, film morphology, structure and optoelectronic properties; 3. Understanding of photophysical processes in the active layer and at material interfaces at various length and time scales, accompanied by an in-depth computational analysis; 4. Studies on device structure and processes therein. The interdisciplinary character of the topics, ranging from material science, physical-chemistry, to device physics and engineering, and theory will attract broad academic interest, with the final aim to integrate the newest fundamental and applied results, to close the gap between fundamental insights and commercially-driven applications.

Topics will include:

  • Material development: synthesis and processing
  • Composition engineering of low dimensional perovskites
  • Relationships between processing and film structure
  • Relation between film morphology, optoelectronic properties and device performance (including solar cells and light-emitting diodes)
