CPE Keynote Seminar with Dr Samuel Stranks from the University of Cambridge

Multimodal microscopy of halide perovskite devices

Abstract:

Halide perovskite solar cells are generating enormous excitement owing to their use in high-performance solar cells, LEDs and detectors. However, there remains performance losses and operational instability pathways in devices that limit their true potential. In this talk I will show a series of multimodal microscopy and operando techniques that seek to unveil micro- and nano-scale connections between luminescence (performance), structural and chemical properties of these materials in devices. I will summarise how these findings inform our current understanding of carrier recombination, diffusion and degradation mechanisms on the micro-scale, and outline strategies to further improve performance and stability.
