Symposium EN10: Novel Approaches to Synthesize and Characterize Stable Halide Perovskites and their Devices

In the last decade, perovskite solar cells (PSCs) have emerged as a low-cost, thin-film technology with unprecedented efficiency gains from 3.8% in 2009 to 25.7% in 2022. Perovskites can be processed from inexpensive solution-based methods and have exceptional material properties that are comparable to established GaAs or Si. The combination of high-quality semiconductors with low-cost deposition techniques are an attractive match creating great excitement and anticipation far beyond academia because PSCs may have the potential to outcompete established thin-film technologies or can be combined with them for further performance enhancements. Although progress has been related mostly to the short-term performance of devices, initially little attention was paid so far to their long-term implications. With a current photovoltaic conversion efficiency compatible with commercialization, long-term stability and up-scaling are receiving more and more attention.

In the past 2 years, there has been a push to understand further the mechanisms that drive stability in perovskite materials, with rapid progress towards stable devices in the long-term. This symposium explores fundamental questions and challenges, focusing on the material’s properties that make perovskites so remarkable, and the current understanding of the device physics, including the raising of lead-free alternatives with a fast growth in the last few years. One main driver were novel synthesis and characterization methods having established a distinct direction within the research community now. The outstanding properties of halide perovskites have not just been successfully applied in solar cells but also in a wide range of optoelectronic devices, such as light-emitting devices, lasers, memristors or detectors. The scope beyond photovoltaics will thus be one main focus of the symposium.

Finally, there is a designated session on the progress of long-term stability, and the evolution towards modules, in order to provide an outlook on how close PSCs are to commercialization.

Topics will include:

  • Material properties
  • Lead-free, fully inorganic, or perovskite-like materials
  • Stability (phase stability, long-term stability, degradation mechanisms, encapsulation…)
  • Testing protocols
  • Space applications
  • Advances in synthesis and characterization
  • Scaling-up: from lab to application
  • Selective contacts: organic and inorganic materials at the interface with the perovskite
  • Perovskite in tandem with other photovoltaic materials
  • Perovskite based light emitting devices, photodetector, photocatalytic or memristors
