Such applications stem from their intriguing optoelectronic properties, such as\u0026nbsp;high absorption coefficient,\u003Cstrong\u003E\u0026nbsp;\u003C\/strong\u003Elong 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. In solar cell applications, I will emphasize two unusual opportunities enabled by metal halide perovskites, including bifacial thin-film solar cells and low-cost thin-film tandem and multi-junction solar cells. Lastly, I will discuss the challenges facing perovskite solar cells, such as large-scale module production, the toxicity of lead, and their vulnerability to moisture, heat, and light.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EYanfa Yan\u003C\/strong\u003E is an Ohio Research Scholar Endowed Chair and a Distinguished University Professor in the Department of Physics and Astronomy at The University of Toledo.
