Abstract
Solar Cells Although methods have been developed that create the photoactive black perovskite phase of formamidinium lead iodide (α-FAPbI3), these routes are temperature and humidity sensitive and less compatible with large-scale solar cell production. Hui et al. report an alternative route in which vertically aligned lead iodide thin films are grown from the ionic liquid methylamine formate. Nanoscale channels in the films lower the barrier to permeation of formamidinium iodide and enable transformation to α-FAPbI3, even at high humidity and room temperature. Solar cells made with these films have power conversion efficiencies as high as 24.1% that display high stability. Science , this issue p. [1359][1] [1]: /lookup/doi/10.1126/science.abf7652
