The effect of multiple ion substitutions on halide ion migration in perovskite solar cells
Samuel R. Pering, Petra J. Cameron
Abstract
This work shows how substitutions to the perovskite lattice at multiple sites can affect iodide ion migration. The triple cation perovskite, Cs 0.05 (FA 0.83 MA 0.17 ) 0.95 Pb(I 0.83 Br 0.17 ) 3 , shows a higher barrier to iodide ion migration than materials with only substitutions at the A-site.
