Research on perovskites has progressed rapidly for PV and LEDs, with new solar-cell efficiency records being set at a regular pace. There are hints of the first commercial products reaching the market by 2020, just a decade since perovskite photovoltaics were first discovered. The MRS Bulletin Materials News podcast presents the impact of a recent advance in this burgeoning field. This episode reports on an all-perovskite tandem solar cell with a record high power-conversion efficiency of 21%.
