The unique opportunities and challenges of metal halide perovskite solar cells

Abstract:  In recent years, the record efficiency of lead halide perovskite-based thin-film solar cells has increased rapidly from 3.8% in 2009 to 25.5% in 2020. Such rapid progress has never been seen before in the history of solar cell development. The unique optoelectronic properties and low-temperature synthesis also provided unprecedented opportunities for the next generation low-cost tandem solar cells. However, despite the exciting progress and opportunities, metal halide perovskite solar cells also face significant challenges, due to the inclusion of toxic Pb and instability against moisture, heat, and irradiation. In this talk, I will provide an overview of the unique opportunities and challenges of metal halide perovskite solar cells.
