Abstract

A combination of high‐resolution mapping techniques is developed to probe the homogeneity and defects of mesoscopic perovskite solar cells. Three types of cells using a one‐step infiltration process with methylammonium lead iodide (MAPbI3) or 5‐ammoniumvaleric acid‐MAPbI3 solutions, or two‐step proc...
