Dissolved-Cl2 triggered redox reaction enables high-performance perovskite solar cells

Nature Communications, 2023
Constructing 2D/3D perovskite heterojunctions is effective for the surface passivation of perovskite solar cells (PSCs). However, previous reports that studying perovskite post-treatment only physically deposits 2D perovskite on the 3D perovskite, and ...
