Vacuum thermal evaporation saved MA-free perovskite

In an article in the June 15, 2022 issue of Joule article, Yi and co-workers reported a novel two-step deposition process, combining spin-coating of cesium/lead precursor firstly with lead chloride additive followed by single-source vacuum thermal evaporation of formamidinium iodide. They achieved a record-high efficiency of methylammonium-free perovskite solar cells surpassing 24% with exceptional stability.
