报告人简介:


Yanfa Yan has been an Ohio Research Scholar Chair and Professor in the Department of Physics and Astronomy at The University of Toledo, since 2011. Previously, he was a Principal Scientist at the National Renewable Energy Laboratory, USA. He earned his Ph. D. in Physics from Wuhan University in 1993. His expertise includes thin-film solar cell fabrication, defect physics of semiconductors, and nanoscale characterization of microstructures, interfaces, and defects in thin-film photovoltaic materials. He is a Fellow of the American Physical Society.

报告摘要:

Organic-inorganic methylammounium lead halide perovskites, CH3NH3PbX3 (X= Cl, Br, I), have revolutionized the field of thin-film solar cells. Within five years, the efficiency of lead halide perovskite-based thin-film solar cells have increased rapidly from 3.8% in 2009 to 22.7% in 2017. Such rapid progress has never been seen before in the history of solar cell development. In this talk, I will review the history and current status of lead halide perovskite thin films solar cells. I will compare lead halide perovskite solar cells with the mainstream solar cells such as Si, Cu(In,Ga)Se2, and CdTe. I will further discuss the unprecedented opportunities of lead halide perovskites. Finally, the intrinsic problems and challenges of lead halide perovskite solar cells will be discussed.
