Abstract:
Halide perovskite semiconductors have emerged as an attractive class of low-cost materials for optoelectronic applications. They benefit from broad tunability in their chemical composition and structure which allows accessing a wide range of properties. However, their easy, low-temperature processability also brings challenges such as defect formation, heterogeneity, structural polymorphism and energetic disorder which are key bottlenecks for applications and scale-up. In this talk, I will provide an overview of how halide perovskites can be designed, synthesized, characterized and applied to devices. I will specifically highlight fabrication methods for structurally-pure low-dimensional materials, advanced characterization techniques to study structure-property relationships, and high performance energy conversion applications. Overall, my talk will emphasize the need to understand nanoscale processes in halide perovskites and identify experimental strategies to overcome pressing challenges for the next-generation of low-cost semiconductor technology.
Bio:
Kunal Datta is a postdoctoral researcher at the department of Applied Physics and Science Education at Eindhoven University of Technology in The Netherlands where he studies diffusion processes in semiconductor materials using ultrafast pump-probe spectro-microscopy. His doctoral research focused on developing materials and device architectures for halide perovskite-based multijunction devices for photovoltaic and solar fuel generation. During his postdoctoral research at Georgia Institute of Technology, he developed physical vapor deposition pathways for low-dimensional perovskites and studied structure-property relationships using synchrotron-based X-ray scattering and ultrafast pump-probe spectroscopy.
