The resulting cell has achieved ... in flexible perovskite solar cells and said SnO 2 was chosen due to its high bulk charge mobility, wide bandgap, and good energy band alignment with perovskite.

“When we added the coating, we got much better energetic alignment of the perovskite ... The cell achieved a power conversion efficiency of 26.3% and an open-circuit voltage of 2.13 eV, as ...
