Engineering perovskites with anions The bandgap of the perovskite top layer in tandem silicon solar cells must be tuned to ∼1.7 electron volts. Usually, the cation composition is varied because the bromine-rich anion compositions with wide bandgaps are structurally unstable. Kimet al. show that by using phenethylammonium as a two-dimensional additive, along with iodine and thiocyanate, bromine-rich perovskite films can be stabilized. A tandem silicon cell delivered &gt;26% certified power conversion efficiency, and a perovskite device maintained 80% of its initial power conversion efficiency of &gt;20% after 1000 hours under illumination.Science , this issue p.155
