TSVP Talk: "Theory of Metal Halide Perovskites" by Yanfa Yan

Title: Theory of Metal Halide Perovskites

Abstract: Organic-inorganic lead halide perovskites have demonstrated exceptional applications in optoelectronic devices, including photodetectors, light-emitting diodes, and solar cells. Such applications stem from their intriguing optoelectronic properties, such as high absorption coefficient, long carrier lifetime, tunable bandgap, and low defect density. In this talk, I will explain why halide perovskites exhibit such exceptional optoelectronic properties, whereas other semiconductors do not. I will discuss the challenges of halide perovskite solar cells, such as the toxicity of lead and their vulnerability to moisture, heat, and light.

Profile: Yanfa Yan is an Ohio Research Scholar Endowed Chair and a Distinguished University Professor in the Department of Physics and Astronomy at The University of Toledo.
